线程UI同步

譬如设置控件的文本,

 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);
            }
        }
