在.NET核心中注册类型T接口的所有实现

// 定义接口
public interface IMyInterface
{
    void MyMethod();
}

// 实现接口
public class MyImplementation1 : IMyInterface
{
    public void MyMethod()
    {
        Console.WriteLine("MyImplementation1");
    }
}

public class MyImplementation2 : IMyInterface
{
    public void MyMethod()
    {
        Console.WriteLine("MyImplementation2");
    }
}

// 注册类型和实现
public void ConfigureServices(IServiceCollection services)
{
    services.AddTransient<IMyInterface, MyImplementation1>();
    services.AddTransient<IMyInterface, MyImplementation2>();
}

// 使用依赖注入
public class MyClass
{
    private readonly IEnumerable<IMyInterface> _implementations;

    public MyClass(IEnumerable<IMyInterface> implementations)
    {
        _implementations = implementations;
    }

    public void MyMethod()
    {
        foreach (var implementation in _implementations)
        {
            implementation.MyMethod();
        }
    }
}
