添加ScreenBody窗口的DoubleClick、MouseDown、MouseUp、MouseMove及Load事件代碼：
private void ScreenBody_DoubleClick(object sender, EventArgs e)
{

g.CopyFromScreen(myRectangle.X, myRectangle.Y, 0, 0, myRectangle.Size);
Clipboard.SetImage(memory);
this.Close();
}
}
private void ScreenBody_MouseDown(object sender, MouseEventArgs e)

}
}

return;
}
