跨线程访问多个控件

private delegate void AddRunTimeDelegate(string strTime);
        private void AddRunTime(string strTime)
        {
            if (textBoxTime.InvokeRequired)
            {
                AddRunTimeDelegate d = new AddRunTimeDelegate(AddRunTime);
                textBoxTime.Invoke(d, new object[] { strTime });
            }
            else
            {
                textBoxTime.Text = strTime;
            }

 }

可以重复使用
public delegate void changeTextHandler(Label sender, string str);
public void changeText(Label sender , string str)
{
//Label sender;
if (sender.InvokeRequired == true)
{
changeTextHandler ct = new changeTextHandler(changeText);
sender.Invoke(ct, new object[] { sender, str });
}
else
{
sender.Text = str.ToString();
}
}

private delegate void AddRunTimeDelegate(string strTime);
        private void AddRunTime(string strTime)
        {
            if (textBoxTime.InvokeRequired)
            {
                AddRunTimeDelegate d = new AddRunTimeDelegate(AddRunTime);
                textBoxTime.Invoke(d, new object[] { strTime });
            }
            else
            {
                textBoxTime.Text = strTime;
            }
        }
