C#创建日志方法

1.通过流的方式

         public void WriteLog(string log)
         {
             StreamWriter stream;
             string path = "D:/WriteLog/";
             if (!Directory.Exists(path))
             {
                 Directory.CreateDirectory(path);
             }
             stream = new StreamWriter(path + "AddVideo.txt", true, Encoding.UTF8);
             stream.WriteLine(DateTime.Now.ToString() + ":" + log);
             stream.Flush();
             stream.Close();
         }
