如何将Serilog应用于asp.net核心mvc

Question

目标：
将Serilog用于asp.net核心mvc，然后在txt文件中检索日志数据。

问题：
代码不起作用。我缺少代码的哪一部分？

信息：
*使用.net 5
*本页代码(https://github.com/serilog/serilog/wiki/Getting-Started)适用于控制台，但不适用于asp.net核心mvc

谢谢！

Answer 1

我们不得不将serilog添加到Program.cs文件中：

public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.ConfigureAppConfiguration((hostingContext, config) =>
{
Log.Logger = new LoggerConfiguration()
.ReadFrom.Configuration(config.Build()).CreateLogger();
})
.UseSerilog()
.UseStartup<Startup>();

请在Asp.core 3.1 MVC中找到一个设置serilog的示例代码https://github.com/pramireddy/Lab.Setup.Serilog.AspMVc
