这里举一个更改Text属性的例子：

1.为了实现更改任意一个控件，这里我定义了一个结构体

public struct SetTextParam

{

   public Control CtrlObject;

   public string strText;

}

2.定义一个委托

delegate void SetTextCallback(SetTextParam stParam);

3.编写改变Text属性的函数

private void SetText(SetTextParam stParam)

{

    if (stParam.CtrlObject.InvokeRequired)

        stParam.CtrlObject.Invoke(new SetTextCallback(SetText), new object[] { stParam });

    else

        stParam.CtrlObject.Text = stParam.strText;

}

重载一个，我更喜欢这样的方式：

private void SetText(Control CtrlObject,string strText)

{

    if (CtrlObject.InvokeRequired)

    {

        SetTextParam stParam;

        stParam.CtrlObject = CtrlObject;

        stParam.strText = strText;

        CtrlObject.Invoke(new SetTextCallback(SetText), new object[] { stParam });

    }

    else

        CtrlObject.Text = strText;

}

4.创建线程函数

private void ThreadProcSafe(object objParam)

{

    SetText((SetTextParam)objParam);

}

 

5.现在可以在别的线程里面改变Control的界面了,如在button1_click中添加如下代码：

SetTextParam stParam;

stParam.CtrlObject = button1;

stParam.strText = "New Button";

Thread newThread = new Thread(new ParameterizedThreadStart(ThreadProcSafe));

newThread.Priority = ThreadPriority.AboveNormal;

newThread.Start(stParam);
