C# 从不是创建控件的线程访问它

创建代理

delegate void SetTextCallback(string text);



创建和启动线程

this.demoThread = 

               new Thread(new ThreadStart(this.ThreadProcUnsafe));

               this.demoThread.Start();



线程中要求改主窗体UI中的text属性

private void ThreadProcSafe()

        {

            this.SetText("This text was set safely.");

        }



调用窗体中的函数用invoke传递参数

private void SetText(string text)

        {

            if (this.textBox1.InvokeRequired)

            {   

                SetTextCallback d = new SetTextCallback(SetText);

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

            }

            else

            {

                this.textBox1.Text = text;

            }

        }
