c# - asp.net 试图为我的网络应用程序创建一个日志文件

Question

我正在尝试将一个 log.txt 文件放在我的应用程序的根目录下，并想写入它。但似乎这不起作用。感谢您的帮助。

错误消息(我认为我没有写入正确的文件，顺便说一句，这是本地主机。如果它是本地主机或网络主机，我希望它能工作):

Access to the path 'C:\Program Files (x86)\Common Files\Microsoft Shared\DevServer\10.0\log.txt' is denied.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

这是我的代码:

 public static void LogErrorMessage(Exception e)
    {
        using (StreamWriter w = File.AppendText("log.txt"))
        {
             Log(e.ToString(),w);
             w.Close();
        }

    }



private static void Log(String logMessage, TextWriter w)
        {
            w.Write("\r\nLog Entry : ");
            w.WriteLine("{0} {1}", DateTime.Now.ToLongTimeString(),
                DateTime.Now.ToLongDateString());
            w.WriteLine("  :");
            w.WriteLine("  :{0}", logMessage);
            w.WriteLine("-------------------------------");
            // Update the underlying file.
            w.Flush();
        }

我认为你需要:

public static void LogErrorMessage(Exception e, string Directory)
{
    using (StreamWriter w = File.AppendText(Directory + "/log.txt"))
    {
         Log(e.ToString(),w);
         w.Close();
    }

}

ASPX 类

public void Page_Load()
   {
      Logger.LogErrorMessage(ex, Server.MapPath("~"));

   }
