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();
        }
