1.需要通过委托操作的控件方法

public void InvokeMessage(string index, string result){    Label lbltip = new Label();    lbltip.BackColor = Color.Transparent;    lbltip.Name = "lbltip";    lbltip.Text = "暂无产品数据!";    lbltip.ForeColor = Color.White;    lbltip.Location = new Point(400, 25);    if (index == "1"){        this.gvBuildList.Controls.Add(lbltip);    }        this.Refresh();}

2.需要委托的方法注册给窗体委托

public void InvokeFrm(string index,string result){    this.Invoke(new InvokeMesage(InvokeMessage), new object[] { index,result });}

测试示例

public static int Main(){      Thread thread = new Thread(new ThreadStart(TestAlpha));    thread.IsBackground = true;    thread.Start();}   public void TestAlpha(){      int i = 0;    while (i < 3)      {        InvokeFrm("1", i++);    }      }
