无法将NLog写入服务器上的光盘

Question

我可以在本地机器上写入NLog，但是当我部署到服务器时，它会失败。

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) 
    { 
     loggerFactory.AddConsole(); 
     loggerFactory.AddDebug(); 
     loggerFactory.AddNLog(); 
     app.AddNLogWeb(); 

     if (env.IsDevelopment()) 
     { 
      app.UseDeveloperExceptionPage(); 
     } 
     else 
     { 
      app.UseExceptionHandler(); 
     } 

     app.UseMvc(); 
     SetAutomapper(); 
     try 
     { 
      var logger = LogManager.GetCurrentClassLogger(); 
      logger.Info("Started Properties Web API"); 
     } 
     catch (Exception e) 
     { 

上述代码位于我的Web API核心项目Startup类中。 该错误消息是

SqlException: Error converting data type nvarchar to datetime. 

我使用存储的过程的标准写入NLOG;

ALTER PROCEDURE [dbo].[NLog_AddEntry_p] (
    @machineName nvarchar(200), 
    @siteName nvarchar(200), 
    @logged datetime, 
    @level varchar(5), 
    @userName nvarchar(200), 
    @message nvarchar(max), 
    @logger nvarchar(300), 
    @properties nvarchar(max), 
    @serverName nvarchar(200), 
    @port nvarchar(100), 
    @url nvarchar(2000), 
    @https bit, 
    @serverAddress nvarchar(100), 
    @remoteAddress nvarchar(100), 
    @callSite nvarchar(300), 
    @exception nvarchar(max) 
) AS 
BEGIN 
    INSERT INTO [dbo].[SIR_NLog] (
    [MachineName], 
    [SiteName], 
    [Logged], 
    [Level], 
    [UserName], 
    [Message], 
    [Logger], 
    [Properties], 
    [ServerName], 
    [Port], 
    [Url], 
    [Https], 
    [ServerAddress], 
    [RemoteAddress], 
    [CallSite], 
    [Exception] 
) VALUES (
    @machineName, 
    @siteName, 
    @logged, 
    @level, 
    @userName, 
    @message, 
    @logger, 
    @properties, 
    @serverName, 
    @port, 
    @url, 
    @https, 
    @serverAddress, 
    @remoteAddress, 
    @callSite, 
    @exception 
); 
END 

所以这里的问题是，记录参数字段必须发送一个字符串，而不是一个日期。为什么会这样？

编辑：我NLog.config是

<?xml version="1.0" encoding="utf-8" ?>

所以我发现这个问题是，区域日期设置为每个服务器上的不同。一个是美国英语，另一个是英国人。 这种情况的最简单的解决方案是删除@logged参数，并使用GetDate（）来获取当前日期。 可能有更好的解决方案。 SQL Server应该都具有相同的日期设置，但我不确定这会造成什么影响。
