C#光盘刻录,windows光盘刻录

摘要：

1、背景：最近，该公司的一个旧项目需要添加将数据导出到CD的功能。添加此功能有点矛盾。光盘

一.背景介绍

最近公司一个老项目需要添加导出数据到光盘的功能.开始对这功能添加有点抵触的.光盘?都啥年代了.

光盘一种即将淘汰的存储媒介.就像当年的随身听,Mp3,Mp4一样,即将退出历史舞台.领导让加,发牢骚归发牢骚,活还是得干哈.

从网上找了一些资料,都是特别古老的文档了.很多方法用起来并不是特别的方便.

1.CodePlex Archive https://archive.codeplex.com/?p=csimapi2samples 其中的例子功能不全,参数都使用dynamic类型,刚开始不了解那些基础概念时,理解起来比较难.可以参考学习.

2.博客:https://blog.csdn.net/huanghunjiuba/article/details/12967463 中的例子BurnCdDemo.

里面的BurnCdDemo对ImApi2做了封装.其实例子里面的封装做的挺不错的.注释也特别全.

在做测试的时候发现刻录功能在本机运行的非常好.在公司的测试机上却获取不到光盘大小,取到的大小是负数.对着Demo的源代码检查了半天,没找到原因.╮(￣▽￣")╭,脑袋好大的.后来找到原因了,在下面的过程中会描述下.

PS:个人不喜欢啥都做抽象.抽象,意味着要多写代码,查找问题也不方便.抽象,依赖注入,控制反转是个好东西,就是要多写许多代码.

个人觉得,很多技术还是要看实际项目情况而使用,没有必要去为了追求使用而滥用.看起来高大上,实际多写了代码维护也不方便.

So,自己搞个简单点的.因为就那么几个功能:获取光驱设备列表,获取光盘信息,添加媒体文件,刻录,进度通知.

二.工欲善其事必先利其器

因工作电脑没有光驱,测试非常不方便.那我们就安装一个虚拟光驱.

推荐一个比较好用的虚拟光驱软件PhantomBurner,带注册码.下载地址:https://download.csdn.net/download/zjhaag/10909339

安装过程就不说了.选下安装路径,一路Next.安装完成后提示重启.其实不重启也可以用.

安装完成后界面如下.在About中输入注册码激活.点击Create,选择Dvd+RW创建Virtual Disc Image.在资源管理器中就可以看到我们创建的虚拟光驱了.

三.开工

1.设备列表获取

(1)首先添加一个RecorderHelper.在RecorderHelper类中添加一个静态方法GetRecorderList用于获取光驱设备列表.

 1         /// <summary>
 2         /// 获取光驱设备列表
 3         /// </summary>
 4         /// <returns></returns>
 5         public static List<Recorder> GetRecorderList()
 6         {
 7             List<Recorder> recordList = new List<Recorder>();
 8 
 9             // Create a DiscMaster2 object to connect to optical drives.
10             MsftDiscMaster2 discMaster = new MsftDiscMaster2();
11             for (int i = 0; i < discMaster.Count; i++)
12             {
13                 if (discMaster[i] != null)
14                 {
15                     Recorder recorder = new Recorder(discMaster[i]);
16                     recordList.Add(recorder);
17                 }
18             }
19             return recordList;
20         }

此时,需要Recorder光驱对象主要属性如下

 1         MsftDiscRecorder2 msRecorder = null;    //Recorder
 2 
 3         /// <summary>
 4         /// 当前磁盘标签
 5         /// </summary>
 6         public string RecorderName { get; private set; }    
 7 
 8         /// <summary>
 9         /// 是否支持当前刻录机
10         /// </summary>
11         public bool IsRecorderSupported { get; private set; }
12 
13         /// <summary>
14         /// 是否支持当前磁盘媒体
15         /// </summary>
16         public bool IsCurrentMediaSupported { get; private set; }
17 
18         /// <summary>
19         /// 当前磁盘可用大小
20         /// </summary>
21         public long FreeDiskSize { get; private set; }
22 
23         /// <summary>
24         /// 当前磁盘总大小
25         /// </summary>
26         public long TotalDiskSize { get; private set; }
27 
28         /// <summary>
29         /// 当前媒体状态
30         /// </summary>
31         public IMAPI_FORMAT2_DATA_MEDIA_STATE CurMediaState { get; private set; }
32 
33         /// <summary>
34         /// 当前媒体状态
35         /// </summary>
36         public string CurMediaStateName { get; private set; }
37 
38         /// <summary>
39         /// 当前媒体类型
40         /// </summary>
41         public IMAPI_MEDIA_PHYSICAL_TYPE CurMediaType { get; private set; }
42 
43         /// <summary>
44         /// 当前媒体类型
45         /// </summary>
46         public string CurMediaTypeName { get; private set; }
47 
48         /// <summary>
49         /// 是否可以刻录
50         /// </summary>
51         public bool CanBurn {get;private set;}

(2)对Recorder各属性进行初始化,赋值.主要方法如下

 1         /// <summary>
 2         /// Recorder Ctor
 3         /// </summary>
 4         /// <param name="uniqueId">标识Id</param>
 5         public Recorder(string uniqueId)
 6         {
 7             this.uniqueId = uniqueId;
 8             msRecorder = new MsftDiscRecorder2();
 9             msRecorder.InitializeDiscRecorder(uniqueId);
10             InitRecorder();
11 
12             this.BurnMediaList = new List<BurnMedia>();
13             this.BurnMediaFileSize = 0;
14         }
15 
16         /// <summary>
17         /// 初始化Recorder
18         /// 更新Recorder信息,更新光盘后可重试.
19         /// </summary>
20         public void InitRecorder()
21         {
22             try
23             {
24                 if (msRecorder.VolumePathNames != null && msRecorder.VolumePathNames.Length > 0)
25                 {
26                     foreach (object mountPoint in msRecorder.VolumePathNames)
27                     {   //挂载点 取其中一个
28                         RecorderName = mountPoint.ToString();
29                         break;
30                     }
31                 }
32                 // Define the new disc format and set the recorder
33                 MsftDiscFormat2Data dataWriter = new MsftDiscFormat2Data();
34                 dataWriter.Recorder = msRecorder;
35 
36                 if (!dataWriter.IsRecorderSupported(msRecorder))
37                 {
38                     return;
39                 }
40                 if (!dataWriter.IsCurrentMediaSupported(msRecorder))
41                 {
42                     return;
43                 }
44                 if (dataWriter.FreeSectorsOnMedia >= 0)
45                 {   //可用大小
46                     FreeDiskSize = dataWriter.FreeSectorsOnMedia * 2048L;
47                 }
48 
49                 if (dataWriter.TotalSectorsOnMedia >= 0)
50                 {   //总大小
51                     TotalDiskSize = dataWriter.TotalSectorsOnMedia * 2048L;
52                 }
53                 CurMediaState = dataWriter.CurrentMediaStatus;  //媒体状态
54                 CurMediaStateName = RecorderHelper.GetMediaStateName(CurMediaState);
55                 CurMediaType = dataWriter.CurrentPhysicalMediaType; //媒介类型
56                 CurMediaTypeName = RecorderHelper.GetMediaTypeName(CurMediaType);
57                 CanBurn = RecorderHelper.GetMediaBurnAble(CurMediaState);   //判断是否可刻录
58             }
59             catch (COMException ex)
60             {
61                 string errMsg = ex.Message.Replace("
", ""); //去掉异常信息里的

62                 this.CurMediaStateName = $"COM Exception:{errMsg}";
63             }
64             catch (Exception ex)
65             {
66                 this.CurMediaStateName = $"{ex.Message}";
67             }
68         }

(3)测试代码如下

 1                     #region 查找光驱设备
 2                     Console.Clear();
 3                     Console.WriteLine("正在查找光驱设备..");
 4                     List<Recorder> recorderList = RecorderHelper.GetRecorderList();
 5                     if (recorderList.Count <= 0)
 6                     {
 7                         Console.WriteLine("没有可以使用的光驱,请检查.");
 8                         Console.WriteLine("请连接光驱后,按任意键重试...");
 9                         Console.ReadKey();
10                         continue;
11                     }
12                     for (int i = 0; i < recorderList.Count; i++)
13                     {
14                         Recorder tempRecorder = recorderList[i];
15                         Console.WriteLine($"发现光驱设备:[{i+1}]  {tempRecorder.RecorderName}");
16                         Console.WriteLine($"媒体类型:{tempRecorder.CurMediaTypeName}");
17                         Console.WriteLine($"媒体状态:{tempRecorder.CurMediaStateName}");
18                         Console.WriteLine("支持刻录:" + (tempRecorder.CanBurn ? "√" : "×"));
19                         Console.WriteLine($"可用大小:{FormatFileSize(tempRecorder.FreeDiskSize)}");
20                         Console.WriteLine($"总大小:{FormatFileSize(tempRecorder.TotalDiskSize)}");
21                     }
22                     if (!recorderList.Any(r=>r.CanBurn))
23                     {

25                         Console.ReadKey();
26                         continue;
27                     }
28                     #endregion

至此,我们完成了对于光驱设备列表的获取及Recorder对象各属性的初始化工作.

说明下,对光驱设备操作需要有管理员权限,没有管理员权限会导致获取失败.对于C#应用程序设置以管理员身份启动请参照https://www.cnblogs.com/babycool/p/3569183.html

2.添加刻录文件

(1)我们为Recorder对象添加待刻录媒体对象列表和待刻录媒体文件大小两个属性

1         /// <summary>
2         /// 待刻录媒体对象List
3         /// </summary>
4         public List<BurnMedia> BurnMediaList {get;set;}
5 
6         /// <summary>
7         /// 待刻录媒体文件大小
8         /// </summary>
9         public long BurnMediaFileSize { get; set; }

View Code

待刻录媒体对象定义如下

 1     /// <summary>
 2     /// 刻录媒体
 3     /// </summary>
 4     public class BurnMedia
 5     {
 6         /// <summary>
 7         /// 路径
 8         /// </summary>
 9         public string MediaPath { get; set; }
10 
11         /// <summary>
12         /// 名称
13         /// </summary>
14         public string MediaName { get; set; }
15 
16         /// <summary>
17         /// 是否是文件夹
18         /// </summary>
19         public bool IsDirectory { get; set; }
20 
21         /// <summary>
22         /// 大小
23         /// </summary>
24         public long Size { get; set; }
25     }

(2)为Recorder对象添加AddBurnMedia方法

 1         /// <summary>
 2         /// 添加刻录媒体对象
 3         /// </summary>
 4         public BurnMedia AddBurnMedia(string path)
 5         {
 6             BurnMedia media = null;
 7             if(string.IsNullOrEmpty(path))
 8             {
 9                 throw new Exception("文件路径不能为空.");
10             }
11             if(!CanBurn)
12             {
13                 throw new Exception("当前磁盘状态不支持刻录.");
14             }
15             media = new BurnMedia();
16             long fileSize = 0;
17             if (Directory.Exists(path))
18             {
19                 DirectoryInfo dirInfo = new DirectoryInfo(path);
20                 fileSize = GetDirectorySize(path);
21                 media.MediaName = dirInfo.Name;
22                 media.MediaPath = dirInfo.FullName;
23                 media.Size = fileSize;
24                 media.IsDirectory = true;
25             }
26             else if (File.Exists(path))
27             {
28                 FileInfo fileInfo = new FileInfo(path);
29                 fileSize = fileInfo.Length;
30                 media.MediaName = fileInfo.Name;
31                 media.MediaPath = fileInfo.FullName;
32                 media.Size = fileSize;
33                 media.IsDirectory = false;
34             }
35             else
36             {
37                 throw new Exception("文件不存在");
38             }
39             if (BurnMediaFileSize + fileSize >= FreeDiskSize)
40             {
41                 throw new Exception("剩余空间不足");
42             }
43             if (BurnMediaList.Any(m => m.MediaName.ToLower() == media.MediaName.ToLower()))
44             {
45                 throw new Exception($"已存在媒体名称为{media.MediaName}的对象");
46             }
47             BurnMediaList.Add(media);
48             BurnMediaFileSize += fileSize;
49             return media;
50         }

22                                 Console.WriteLine($"添加成功:{filePath}");
23                                 Console.WriteLine("文件大小:" + FormatFileSize(media.Size));
24                                 Console.WriteLine("已添加文件总大小:" + FormatFileSize(recorder.BurnMediaFileSize));
25                             }

3.刻录及刻录进度通知

为Recorder对象添加Burn方法.同时,添加刻录进度通知.

(1)添加BurnProgressChanged委托用于通知刻录进度

1     /// <summary>
2     /// 刻录进度delegate
3     /// </summary>
4     public delegate void BurnProgressChanged(BurnProgress burnProgress);

View Code

刻录进度通知对象定义如下(其属性为根据需求添加):

 1     /// <summary>
 2     /// 刻录进度对象
 3     /// </summary>
 4     public class BurnProgress
 5     {
 6         /// <summary>
 7         /// 当前操作
 8         /// 对应IMAPI2.IMAPI_FORMAT2_DATA_WRITE_ACTION枚举
 9         /// 4 正在写入数据 5完成数据写入 6 刻录完成
10         /// </summary>
11         public int CurrentAction { get; set; }
12 
13         /// <summary>
14         /// 当前操作Name

C#光盘刻录第34张

四.BurnCdDemo获取磁盘大小为负数bug

在开始的时候,我们说了使用BurnCdDemo获取光盘大小为负数.在实际开发的过程中,也碰到了.因为我们买的光盘太大了?达到8G,实际模拟刻录时,没那么大.所以没啥问题.

我们看BurnCdDemo里Recorder对象的代码:

1 private long m_nDiskSize = 0;
2 private long m_nUseableSize = 0;
3 
4 //可用的
5 m_nUseableSize = msFormat.FreeSectorsOnMedia * 2048;
6 //总大小
7 m_nDiskSize = msFormat.TotalSectorsOnMedia * 2048;

msFormat.FreeSectorsOnMedia和msFormat.TotalSectorsOnMedia类型为int.大家想到原因了吧.int溢出了.所以把后面的2048改为2048L就可以了.看似正常的代码,以后在碰到类型转换时要多注意些.
