.net Mvc 用txt文件记录报错信息日志

.代码

public static void Writelog(string msg)
        {
            StreamWriter stream;
            //写入日志内容
            string path = "C:/日志";
            //检查上传的物理路径是否存在，不存在则创建
            if (!Directory.Exists(path))
            {
                Directory.CreateDirectory(path);
            }
            stream = new StreamWriter(path + "\\log.txt", true, Encoding.Default);
            stream.Write(DateTime.Now.ToString() + ":" + msg);
            stream.Write("\r\n");
            stream.Flush();
            stream.Close();
        }

在引用相联的包就可以了
