自定义Log日志

新建一个 DataLog类 用来存放生成Log日志方法

#region 写日志
        public void WriteLogEx(string sendJson, string code = "", string msg = "", string fileName = "")
        {
            string path = AppDomain.CurrentDomain.BaseDirectory;
            string logDir = "log";
            logDir += "\" + DateTime.Now.ToString("yyyy") + "\" + DateTime.Now.ToString("MM");
            path = Path.Combine(path, logDir);
            if (!Directory.Exists(path))
            {
                Directory.CreateDirectory(path);
            }
            try
            {
                StringBuilder log = new StringBuilder();
                log.Append(Environment.NewLine);
                log.Append("================BEGIN");
                log.Append(DateTime.Now);
                log.Append("================");
                log.Append(Environment.NewLine);
                log.Append(sendJson);
                log.Append(Environment.NewLine);
                log.Append("调用HTTP请求,返回的数据结果:{"code":" + code + ","msg":" + msg + "}");
                log.Append(Environment.NewLine);
                log.Append("================END ");
                log.Append(DateTime.Now);
                log.Append("================");
                log.Append(Environment.NewLine);

                fileName = string.IsNullOrWhiteSpace(fileName) ? DateTime.Now.Day.ToString() + "日" : fileName;
                fileName = fileName + ".txt";
                string file = Path.Combine(path, fileName);
                System.IO.File.AppendAllText(file, log.ToString(), System.Text.Encoding.Default);
            }
            catch { }
        }
        #endregion

使用的话直接实例化，调方法。
