C#线程中使用委托实现textbox显示

delegate void SetTextCallback(string text);//后加的，好好想一想,参数是SetText带的参数。//From:www.uzhanbao.com

        private void SetText(string text)
        {
            if (this.tBoxResult.InvokeRequired)
            {
                SetTextCallback d = new SetTextCallback(SetText);
                this.Invoke(d, new object[] { text });
            }
            else
            {
                this.tBoxResult.AppendText(text);
                this.tBoxResult.Refresh();
            }
        }

调用：

SetText("test");
