线程UI同步

 只用一次:

 this.Invoke(new MethodInvoker(() => { this.btnGo.Enabled = true; MessageBox.Show("Yeah ! "); }));

　或

 Invoke(new Action(
                () =>
            {
                this.button2.Text = "bbb";
            })
            );

　　

　

譬如设置控件的文本, 可以统一封装

 private void SetControlText2(Control c, string text)
        {
            if (c.InvokeRequired)
            {
                this.Invoke(new MethodInvoker(delegate() { SetControlText2(c, text); }), c, text);
            }
            else
            {
                c.Text = text; ;
               
            }
        }

 上面这是简易的写法,要写成下面这种也可以;

 private delegate void SetControlTextCallBack(Control c, string text);
        private void SetControlText(Control c,string text)
        {
            if (c.InvokeRequired)
            {
                this.Invoke(new SetControlTextCallBack(SetControlText), c,text);
            }
            else
            {
                c.Text = text; ;
                // btnTest.Text =bool( o);
            }
        }

 使用Action写法:

 private Action<Control, string> SetText;

//赋值:
    SetText = (c, s) =>
            {
                if (this.InvokeRequired)
                {
                    Invoke(SetText,c,s);
                }
                else
                {
                    c.Text = s;
                }
            };    
//调用:
 ThreadStart t = new ThreadStart(() => { SetText(button2, "aaa"); });
