C# 不同窗口传递参数

form1:
private void button1_Click(object sender, System.EventArgs e)
{
Form2 frm = new Form2();
frm.OnSendString += (text) => { textBox1.Text = text; };
frm.Show();
}form2:
public delegate void SendStringHandler(String text);
public event SendStringHandler OnSendString; private void button1_Click(object sender, EventArgs e)
{
if (OnSendString != null)
{
OnSendString("在WinForms程序里实现窗体传值的最佳实践");
}
}

m_dlg.TextBoxChanged += new EventHandler(
(sender1, e1) =>
{ richTextBox1.Text = m_dlg.TextBoxValue; }
);=>相当于m_dlg.TextBoxChanged += new EventHandler(m_dlg_textboxchanged);...private void m_dlg_textboxchanged(object sender1, EventArgs e1)
{
richTextBox1.Text = m_dlg.TextBoxValue;
}
