C# 两个窗体传值,不管From2是否打开，窗体From1必须传值给From2,怎么实现呢？
两个窗体传值
比如：用委托，窗体From1传值给另外一个窗体From2（点击From1上的按钮将弹出窗体From2）,是不

是要From2必须打开？（yes,要2打开）
父窗体From1:

public partial class frMainDlg : Form
{
public static frMsg m_frMsg = null;

public frMainDlg()
{
InitializeComponent();
m_frMsg = new frMsg();
}



private void button2_Click(object sender, EventArgs e)
{
string txtMsg = "fdsfsrtrtrtretrrdfdsfsd";
ThreadWriteMsgToTextBox(txtMsg);

}


private void ThreadWriteMsgToTextBox(string strText)
{
if (m_frMsg != null)
{
m_frMsg.ThreadWriteMessageToTextBox(strText);

}


}

}


子窗体From2：



public delegate void DelegateWriteMessageToTextBox(string strMessage);

public void ThreadWriteMessageToTextBox(string strMessage)
{

#region code
DelegateWriteMessageToTextBox delegateWmt = new

DelegateWriteMessageToTextBox(WriteMessageToTextBox);
try
{
this.BeginInvoke(delegateWmt, strMessage);
}
catch
{

}
#endregion
}
private void WriteMessageToTextBox(string strMessage)
{
#region CODE
lock (this.txt_Message)
{
try
{
txt_Message.AppendText(strMessage + "\n\r");

}
catch
{ }
}
#endregion
}





不管From2是否打开，窗体From1必须传值给From2，而且只要整个程序不退出，只要打开From2都可以看到From1传过来的值，怎么实现呢？

委托实现
