双击dataGridView一行数据，打开一个另一个窗体，并把双击行的数据展示出来

本文是以list为数据源，双击获取一个list实例，并把这个实例传到另一个窗体，并把所得实例的数据展示出来。

// frmEmployeeList.cs

//dataGridView1双击事件CellDoubleClick

private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)

{
frmSave f3 = new frmSave();
var visit = this.dataGridView1.CurrentRow.DataBoundItem as EmployeeList;//visit 相当于一个实体
f3.DataEntity = visit;
f3.Show();
}

//frmSave.cs

List<EmployeeList> emp=new List<EmployeeList>();

public EmployeeList DataEntity
{
get
{
return this.m_DataEntity;
}
set
{
if (value == null)
return;
this.m_DataEntity = value;
this.DisplayData();
}
}
EmployeeList m_DataEntity;

public void DisplayData()

{

this.btId.text=this.m_DataEntity.empid;

this.btAge.text=this.m_DataEntity.empage;

this.btname.text=this.m_DataEntity.empname;

}

//EmployeeList.cs

public class Employee

{

public string empid;

public in empage;

public string empname;

}
