Silverlight写错误日志

说明是在基于网站的Silverlight项目
日志是记录在网站工程的目录，部署到IIS上之后，日志是下载IIS虚拟目录下的

参考代码

    public class MyLog
    {
        public static void WriteErrLog(string strErrMod,string strErrDesc)
        {
            StreamWriter sw;
            string strErrLog =
                System.AppDomain.CurrentDomain.BaseDirectory + @"gErr.txt";   //获取写日志的路径             if (File.Exists(strErrLog))             {                 FileInfo oFile = new FileInfo(strErrLog);                 if (oFile.Length > 1024000)                 {                     oFile.Delete();                 }             }             if (File.Exists(strErrLog))             {                 sw = File.AppendText(strErrLog);             }             else             {                 sw = File.CreateText(strErrLog);             }             string strDate = "出错时间:" + string.Format("{0:yyyy-MM-dd HH:mm:ss}",DateTime.Now);             string strErrMoudle = "出错模块:" + strErrMod;             string strErrDescOut = "错误原因:" + strErrDesc;             sw.WriteLine(strDate);             sw.WriteLine(strErrMoudle);             sw.WriteLine(strErrDescOut);             sw.WriteLine("===================================================================");             sw.Flush();             sw.Close();         }     }
