摘要：
//方法1://使用System引用命名空间。绘画颜色类型的十六进制颜色代码：ColorTranslator。FromHtml（颜色）；颜色类型转换为十六进制颜色代码：ColorTranslator ToHtml（_Color）；//方法2:///////将字符串转换为Color//////
//方法1：
//引用命名空间 using System.Drawing;
16进制颜色代码转Color类型：ColorTranslator.FromHtml(color);
Color类型转16进制颜色代码：ColorTranslator.ToHtml(_color);
//方法2：
/// <summary>
/// 将字符串转换为Color

/// <param name="color">带#号的16进制颜色</param>
