.net6使用Nlog

NLog

安装NuGet(NLog.Web.AspNetCore)

添加一个NLog.config文件

<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      autoReload="true"
      throwExceptions="false"
      internalLogLevel="Off" internalLogFile="E:\temp\nlog-internal.log">
	<targets>
    //保存在E:\学习文档\C#\Nlog\WebApplication1\WebApplication1\bin\Debug\net6.0\logs
	
	targets>>
	<rules>
		
		
		
		<logger name="Microsoft.*" minlevel="Trace"  final="true" />
		<logger name="*" minlevel="Debug" writeTo="f" />
	rules>
nlog>

在progarm.cs中配置

using WebApplication1.Model;

namespace WebApplication1

            Configure(builder);

            var app = builder.Build();

            Configution(app);
        }

        public static void Configure(WebApplicationBuilder builder)
        {
            // Add services to the container.

            //依赖注入
            builder.Services.AddScoped();

            if (app.Environment.IsDevelopment())
