通过接口动态创建类 [英] Dynamically create a class by interface

问题描述

当我能够动态生成方法时，我对 .Net表达式有一定的了解。很好，很好。

I have some expirience with .Net Expressions, when I'm able to dynamically generate methods. It's fine, it's good.

但是现在我需要生成一个完整的类，并且看来唯一的方法是发出整个IL，这是完全不可接受的（

But now I need to generate a whole class, and it seems that the only way to do it is Emit whole IL which is totally inacceptable (it's impossible to support).

假设我们有以下界面：

public interface IFoo
{
    [Description("5")]
    int Bar();
    [Description("true")]
    bool Baz();
}

应转换为：

public class Foo : IFoo
{
    public int Bar() => 5;
    public bool Baz() => true;
}

如何实现？如果没有第三方工具和库，是否有可能？我知道GitHub上有很多有用的utils，但是我真的不想导入整个MVVM框架来生成一些代码。

How can I achieve it? Is it even possible without 3rd party tools and libs? I know there is plenty of useful utils on GitHub, but I really don't want to import a whole MVVM framework to just make some code generation.

使用 Expressions ，并使用我已经使用它生成的方法创建一个类。但是现在我还不知道该怎么做。

If I could just use Expressions, and create a class with methods I already generated with it. But for now I don't know how to do it.

推荐答案

我实际上正在使用 CodeGeneration.Roslyn 程序包，它使您可以集成到MSBuild管道中并生成内容。例如，请参阅我的 REST摇摇或固体-> C＃代码生成。

I'm actually currently using CodeGeneration.Roslyn package that allows you to integrate into MSBuild pipeline and build stuff. For example, see my REST swagger or solidity -> C# codegen.
