C#输出log信息

在写程序的过程中，有时候我们需要添加一些log信息，这个时候，可以采用下面的方法来实现。

        public static void WriteLog(string ExtraMsg, Exception e)
        {
           string logPath = Environment.CurrentDirectory + "\\Log";
            if (!Directory.Exists(logPath))
            {
                Directory.CreateDirectory(logPath);
            }

           string logFilePath = Path.Combine(logPath, string.Format("{0}.log", DateTime.Now.Date.ToString("yyyyMMdd")));
           if (e is System.Threading.ThreadAbortException)
               return;

           string strMsg = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss") + "   " + e.Message;
           string detailMsg = string.Format("类型:{0}\r\n堆栈:{1})", e.GetType().Name, e.StackTrace);
           using (StreamWriter sw = new StreamWriter(logFilePath, true))
           {
               sw.WriteLine(strMsg);
               sw.WriteLine(ExtraMsg);
               sw.WriteLine(detailMsg);
               sw.WriteLine();
               sw.Close();
           }
        }
