    public static class Log
    {
        public static void WriteLine(string line)
        {
            try
            {
                System.Diagnostics.Debug.Assert((line != null), " public static void WriteLine(string line) line 不能为空!");
                line = String.Format("#############{0}################## \r\n{{\r\n   {1}  \r\n}}\r\n", DateTime.Now.ToString(), line);
                line += "%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%\r\n\r\n\r\n";
                line = "%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%\r\n" + line;
                lock (line)
                {
                    //增加每一天记录一个Log文件
                    string FileName = string.Format("~/Sys_Log/{0}.log", DateTime.Now.ToString("yyyy-MM-dd"));
                    string FilePath=System.Web.HttpContext.Current.Request.MapPath(FileName);
