将异常写入日志文件。 [英] Writing Exception to a log file.

问题描述

我有一个接受一般异常作为参数的方法。

每当try catch抛出异常（指定异常类型）时我想将它传递给我的方法。



最终会写一个日志文件。



任何人都可以帮忙。

I have a method which accepts a general exception as parameter.
Whenever a try catch throws exception (with exception type specified) i wants to pass it to my method.

Which will ultimately write a log file.

can anyone help.

推荐答案

在web.config中添加一个LogFilePath条目

Add A LogFilePath entry in web.config

<appSettings>
   <add key="LogFilePath" value="C:\\LogFile.txt"/>
 </appSettings>

使用静态方法WriteLog（）创建一个Looger类;

Create A Looger Class With static method WriteLog() ;

public class Logger
{

    public static string LogFile { get { return ConfigurationManager.AppSettings["LogFilePath"]; } }

    public static void WriteLog(Exception ex)
    {
        using (FileStream fs = new FileStream(LogFile, FileMode.Append, FileAccess.Write))
        {
            using (StreamWriter sw = new StreamWriter(fs))
            {
                sw.WriteLine(ex.Message+"||"+ex.StackTrace);
            }
        }
    }
}

现在您可以在应用程序中调用WriteLog方法

Now You can call your WriteLog mthod in your Application as

try
      {
          throw new Exception("new exception got");
      }
      catch (Exception ex)
      {
          Logger.WriteLog(ex);
      }

注意：请完全访问要写入日志文件的文件夹。在这种情况下，它是C Drive。
