通常都用log4net

public static void WriteLog(string msg, string logName, string path){var Log = "";Log += msg + "\r\n";if (Directory.Exists(path) == false){Directory.CreateDirectory(path);}if (!System.IO.File.Exists(path + "/" + logName + "_Log" + DateTime.Today.ToString("yyyy-MM-dd") + ".txt")){FileStream fs1 = new FileStream(path + "/" + logName + "_Log" + DateTime.Today.ToString("yyyy-MM-dd") + ".txt", FileMode.Create, FileAccess.Write); StreamWriter sw = new StreamWriter(fs1);sw.WriteLine(Log);sw.Close();fs1.Close();}else{FileStream fs = new FileStream(path + "/" + logName + "_Log" + DateTime.Today.ToString("yyyy-MM-dd") + ".txt" + "", FileMode.Append, FileAccess.Write);StreamWriter sr = new StreamWriter(fs);sr.WriteLine(Log);sr.Close();fs.Close();}}

一天生成一個，根據名字可生成不同的日志。
