MvvmCross 7 如何在 WPF (.net Core 3.1) 应用程序中设置 Serilog [英] MvvmCross 7 How to setup Serilog in WPF (.net Core 3.1) application

问题描述

我在这里的第一篇文章，希望我会问一个有价值的问题，如果回答可能会帮助我和其他人理解 MvvmCross 的复杂性.

My first post here, hopefully I will ask a merit question that if answered maybe will help me and the others to understand the complexities of MvvmCross.

我有一个问题要问熟悉 MvvmCross 框架的人.我正在使用 MvvmCross 7.1.2 版本，并且正在尝试在我的 WPF(.net Core 3.1)应用程序中设置 Serilog 日志记录.

I have a question to people familiar with MvvmCross framework. I'm using MvvmCross 7.1.2 version and I'm trying to setup Serilog logging in my WPF (.net Core 3.1) application.

MvvmCross 的典型项目结构:Project.Core .net 标准 2.0；Project.Wpf .net Core 3.1

Project structure is typical for MvvmCross: Project.Core .net Stardard 2.0; Project.Wpf .net Core 3.1

我在 Project.Wpf 项目中创建了 Setup.cs 类，该类继承自 MvxWpfSetup 并根据 MvvmCross 文档覆盖了两个方法 GetDefaultProviderType() 和 CreateLogProvider():

I created Setup.cs class in Project.Wpf project which inherits from MvxWpfSetup and overrode two methods GetDefaultProviderType() and CreateLogProvider() as per MvvmCross documentation:

public class Setup : MvxWpfSetup
{
    public override MvxLogProviderType GetDefaultLogProviderType() => MvxLogProviderType.Serilog;

    protected override IMvxApplication CreateApp()
    {
        throw new NotImplementedException();
    }

    protected override IMvxLogProvider CreateLogProvider()
    {
        Log.Logger = new LoggerConfiguration()
                    .MinimumLevel.Debug()
                    .WriteTo.File($"{Directory.GetCurrentDirectory()}\\my_log.log")
                    .CreateLogger();
        return base.CreateLogProvider();
    }
}

App.xaml.cs 是标准的我在引入记录器时没有改变任何东西:

App.xaml.cs is standard I haven't change anything when introducing the logger:

public partial class App : MvxApplication
{
    protected override void RegisterSetup()
    {
        this.RegisterSetupType<MvxWpfSetup<Core.App>>();
    }
}

在 App.cs 的 Project.Core 中，我只注册应用程序启动:

In Project.Core in App.cs I register app start only:

public class App : MvxApplication
{
    public override void Initialize()
    {
        RegisterAppStart<LoginViewModel>();
    }
}

在 ViewModel 的 Project.Core 中，我使用构造函数注入来获取记录器:

In Project.Core in ViewModel I use constructor injection to obtain the logger:

public class LoginViewModel : MvxViewModel
{
    #region Fields
    private readonly IMvxLog _log;
    #endregion
    public LoginViewModel(IMvxNavigationService navigationService, IMvxLogProvider log)
    {
        _log = log.GetLogFor<LoginViewModel>();
    }
}

当我使用 _log.Info("Log this information.");在调试模式下，我看到记录器是彩色控制台"而不是 Serilog - 从未执行过 Setup.cs 并且未创建记录器.

When I use _log.Info("Log this information."); in Debug mode I see that the logger is 'Coloured Console' instead of Serilog - Setup.cs was never executed and the logger wasn't created.

问题:我应该如何使用 Setup.cs?需要初始化吗?我在这里错过了什么?

Question: How should I use Setup.cs? Does it require initialisation? What am I missing here?

问候，卡罗尔

推荐答案

答案就是 App.xaml.cs 中的那一行:

The answer is that line in App.xaml.cs:

MvxWpfSetupSingleton.EnsureSingletonAvailable(Dispatcher, MainWindow);

它初始化"Setup.cs 和同样的记录器.

It 'initializes' the Setup.cs and the same the logger.
