msdn中有这么一种解决方法,但很不实用,想通过修改来扩大其适应性,但出错了.哪位大侠解释解释?
delegate void SetTextCallback(string text);
private void SetText7(string text)
{
// InvokeRequired required compares the thread ID of the
// calling thread to the thread ID of the creating thread.
// If these threads are different, it returns true.
if (this.label7.InvokeRequired)
{
SetTextCallback d = new SetTextCallback(SetText7);
this.Invoke(d, new object[] { text });
}
else
{
this.label7.Text = text;
}
}

尝试着改为:
delegate void SetTextCallback(string text,Label e);
private void SetText(string text,Label e)
{
// InvokeRequired required compares the thread ID of the
// calling thread to the thread ID of the creating thread.
// If these threads are different, it returns true.
if (e.InvokeRequired)
{
SetTextCallback d = new SetTextCallback(SetText);
this.Invoke(d, new object[] { text });
}
else
{
e.Text = text;
}
}
SetText(text,label1);//调试时出错.

this.Invoke(d, new object[] { text,e });

簽名,參數必須一致
