C#异常日志

代码比较简单，仅提供一种思路

/// <summary>
/// 将异常打印到LOG文件
/// </summary>
/// <param name="ex">异常</param>
/// <param name="LogAddress">日志文件地址</param>
public static void WriteLog(Exception ex, string LogAddress = "")
{
  //如果日志文件为空，则默认在Debug目录下新建 YYYY-mm-dd_Log.log文件
  if (LogAddress == "")
  {
      LogAddress = Environment.CurrentDirectory + '\' +
          DateTime.Now.Year + '-' +
          DateTime.Now.Month + '-' +
          DateTime.Now.Day + "_Log.log";
  }

  //把异常信息输出到文件
  StreamWriter sw = new StreamWriter(LogAddress, true);
  sw.WriteLine("当前时间：" + DateTime.Now.ToString());
  sw.WriteLine("异常信息：" + ex.Message);
  sw.WriteLine("异常对象：" + ex.Source);
  sw.WriteLine("调用堆栈：
" + ex.StackTrace.Trim());
  sw.WriteLine("触发方法：" + ex.TargetSite);
  sw.WriteLine();
  sw.Close();
}
