如何将依赖项传递给Serilog Enricher？ [英] How do I pass a dependency to a Serilog Enricher?

问题描述

我在应用程序中使用Serilog进行日志记录。在配置记录器时，我的代码是这样的：

I'm using Serilog in my application for logging. When I'm configuring the logger, I have code like this:

var log = new LoggerConfiguration()
    .Enrich.With<MySerilogEnricher>()
    .ReadAppSettings()
    .CreateLogger();

我想向我的 MySerilogEnricher 类，但是当我尝试时，出现此编译器错误：

I want to inject some dependencies into my MySerilogEnricher class, but when I try, I get this compiler error:

错误CS0310： SerilogEnricher必须是具有以下内容的非抽象类型一个
公共无参数构造函数，以便将其用作通用类型或方法
'LoggerEnrichmentConfiguration.With（）'中的参数
'TEnricher'

error CS0310: 'SerilogEnricher' must be a non-abstract type with a public parameterless constructor in order to use it as parameter 'TEnricher' in the generic type or method 'LoggerEnrichmentConfiguration.With()'

我理解为什么会收到此错误，但是我看不到解决它的简单方法。理想情况下，应该有一个 WithInstance 调用，我可以这样使用：

I understand why I'm getting this error, but I don't see an easy way around it. Ideally, there'd be a WithInstance call that I could use like this:

var instance = new MySerilogEnricher(myDependency);
var log = new LoggerConfiguration()
    .Enrich.WithInstance<MySerilogEnricher>(instance)
    .ReadAppSettings()
    .CreateLogger();

有没有办法将依赖项传递给 MySerilogEnricher ？我也许可以在其中包含一个带有MySerilogEnricher的类，并将其依赖项传递给属性，但这似乎很麻烦。

Is there any way to pass a dependency to MySerilogEnricher? I could maybe have a class with MySerilogEnricher in it and pass the dependency to it in a property, but that seems messy.

推荐答案

您可以使用 .With（）方法，而无需使用泛型来传递扩展程序实例。因此，在您的示例中，将是：

You can use the .With() method without the generic to pass an instance of your enricher. So in your example, it would be:

var instance = new MySerilogEnricher(myDependency);
var log = new LoggerConfiguration()
    .Enrich.With(instance)
    .ReadAppSettings()
    .CreateLogger();
