ProxyInterfaceGenerator

This project uses Source Generation to generate an interface and a Proxy class for classes. This makes it possible to wrap external classes which do not have an interface, in a Proxy class which makes it easier to Mock and use DI.

It supports:

properties
methods
events
implicit and explicit operators

Info

Given: an external existing class which does not implement an interface

public sealed class Person
{
    public string Name { get; set; }

    public string HelloWorld(string name)
    {
        return $"Hello {name} !";
    }
}

Create a partial interface And annotate this with ProxyInterfaceGenerator.Proxy[...] and with the Type which needs to be wrapped:

[ProxyInterfaceGenerator.Proxy(typeof(ProxyInterfaceConsumer.Person))]
public partial interface IPerson
{
}

When the code is compiled, this source generator creates the following two items:

1. An additional partial interface Which defines the same properties and methods as in the external class.

public partial interface IPerson
{
    string Name { get; set; }

    string HelloWorld(string name);
}

2. A Proxy class Which takes the external class in the constructor and wraps all properties and methods.

public class PersonProxy : IPerson
{
    public Person _Instance { get; }

    public PersonProxy(Person instance)
    {
        _Instance = instance;
    }

    public string Name { get => _Instance.Name; set => _Instance.Name = value; }

    public string HelloWorld(string name)
    {
        string name_ = name;
        var result_19479959 = _Instance.HelloWorld(name_);
        return result_19479959;
    }
}

Use it

IPerson p = new PersonProxy(new Person());
p.Name = "test";
p.HelloWorld("stef");
