Why can not I reply you in Chinese. Once I select sogou,it is handled.

As to the question,can you explain it in more details?

Thanks！

@〆.落若兮。: 我不知道你具体要实现什么功能,下面是我一个非UI线程,输出log到textBox的方法,

　　 delegate void OneStringParmenters(string s);
        /// <summary>
        /// 输出日志到窗口
        /// </summary>
        /// <param name="strLog"></param>
        public void UpdateLog(string strLog)
        {
            if (this.InvokeRequired)
            {
                this.BeginInvoke(new OneStringParmenters(UpdateLog), strLog);
            }
            else
            {
                txtLog.AppendText(string.Format("{0}:{1}\r\n", DateTime.Now.ToString("G"), strLog));
            }
        }
