C# 将日期添加到ASP.NETCore2.1默认记录器

我使用的是ASP.NET的默认记录器，它可以创建这样的日志

info: Microsoft.AspNetCore.DataProtection.KeyManagement.XmlKeyManager[0]
      User profile is available. Using 'C:\Users\Test\AppData\Local\ASP.NET\DataProtection-Keys' as key repository and Windows DPAPI to encrypt keys at rest.
warn: Microsoft.EntityFrameworkCore.Model.Validation[10400]
      Sensitive data logging is enabled. Log entries and exception messages may include sensitive application data, this mode should only be enabled during development.

但我想把DateTime附加到它上面

[2019.12.19 10:00] info: Microsoft.AspNetCore.DataProtection.KeyManagement.XmlKeyManager[0]
      User profile is available. Using 'C:\Users\Test\AppData\Local\ASP.NET\DataProtection-Keys' as key repository and Windows DPAPI to encrypt keys at rest.
[2019.12.19 10:00] warn: Microsoft.EntityFrameworkCore.Model.Validation[10400]
      Sensitive data logging is enabled. Log entries and exception messages may include sensitive application data, this mode should only be enabled during development.

我尝试使用Serilog，但无法获取默认日志，只能获取我直接创建的

日志错误（“错误”）已显示。
在ASP.Net Core中，您可以将记录器配置为包含时间戳

public class Program
    {
        public static void Main(string[] args)
        {
            CreateWebHostBuilder(args).Build().Run();
        }

        public static IHostBuilder CreateWebHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
            .ConfigureLogging(logger=>
            {
                logger.AddConsole(x => x.TimestampFormat = "[HH:mm:ss] "); 
            })
            .ConfigureWebHostDefaults(webBuilder =>

在github上，内置的.NET Core控制台记录器不记录日期时间

您可以尝试自动记录时间戳

1.使用AddConsoleAdvanced方法自定义LoggerBuilderExtensions

        //So, a configuration section must be passed to configure the logger.
