        st.Start();
        for(int i =0; i<100000; i++)
        {
             console.writeLine('输出');
        }
        st.Stop();
        TimeSpan ts = st.Elapsed;
        BaseHelper.WriteLogs("经办流程列表", String.Format("共计{0}人，耗时{1}ms,{2}分钟:", allUser.Count() + "", ts.TotalMilliseconds + "", ts.TotalMinutes + ""));
