WPF Nlog日志模块使用

1. 新建一个基于Prism框架的应用程序，在管理NuGet程序包工具中搜索下载这几个包   
   1. Nlog
   2. NLog.Config
   3. NLog.Ectensions.Logging
   4. Microsoft.Extensions.Logging
   5. Microsoft.Extensions.DependencyInjection
   6. DryIoc.Microsoft.DependencyInjection
   7. 

    

2. 在App.xaml.cs中把Nlog包注入到Dryloc容器中

   using DryIoc;
   using MCAutomationTestApp.Common;
   using MCAutomationTestApp.Common.Models;
   using MCAutomationTestApp.Service;
   using MCAutomationTestApp.ViewModels;
   using MCAutomationTestApp.Views;
   using MCAutomationTestApp.Views.Dialogs;
   using Microsoft.Extensions.DependencyInjection;
   using Microsoft.Extensions.Logging;
   using NLog.Extensions.Logging;
   using Prism.DryIoc;
   using Prism.Ioc;
   using Prism.Services.Dialogs;
   using System.Diagnostics;
   using System.Windows;
   using DryIoc.Microsoft.DependencyInjection;     
      protected override IContainerExtension CreateContainerExtension()
           {
               var serviceCollection = new ServiceCollection();
               serviceCollection.AddLogging(configure => {
                   configure.ClearProviders();
                   configure.SetMinimumLevel(LogLevel.Trace);
                   configure.AddNLog();
               });
               return new DryIocContainerExtension(new Container(CreateContainerRules()).WithDependencyInjectionAdapter(serviceCollection));
           }

3. 重新生成项目，然后找到执行文件目录下Nlog.config,打开做一下修改并保存

4. 使用方法

    private readonly Logger logger; 
    public IndexViewModel(Logger logger)
           {
               this.logger = logger;
           }
   private void Add(string obj)
           {
               logger.LogInformation("测试日志");
           }

5. 在执行文件目录下会生成logs目录
