C# 在.NET Core DI中，是否有方法获取正在解析的类型？

我正在实际使用Microsoft.Extensions.DependencyInjection库（.NET Core 3.1），并试图找到一种基于正在解析的类型创建实例的方法

说明，让我们考虑下面的类、接口和主：

interface ISomeService
{
}

class SomeService1 : ISomeService
{
}

class SomeService2 : ISomeService
{
}

class SomeTypeBeingResolvedA
{
    public SomeTypeBeingResolvedA(ISomeService someService)
    {
    }
}

class SomeTypeBeingResolvedB
{
    public SomeTypeBeingResolvedB(ISomeService someService)
    {
    }
}

static void Main(string[] args)
{
    var serviceCollection = new ServiceCollection();

    serviceCollection.AddTransient<ISomeService>((IServiceProvider provider) =>
    {
        Type typeBeingResolved = ???; // <- How can I get this?
        if(typeBeingResolved == typeof(SomeTypeBeingResolvedA))
            return new SomeService1();
        if (typeBeingResolved == typeof(SomeTypeBeingResolvedB))
            return new SomeService2();
        ...
    });
}

接口服务
{
}
类SomeService1:ISomeService
{
}
类SomeService2:isomService
{
}
类SomeTypeBeingResolvedA
{
公共SomeTypeBeingResolvedA（等轴服务someService）
{
}
}
类SomeTypeBeingResolvedB
{
公共SomeTypeBeingResolvedB（ISomeService someService）
{
}
}
静态void Main（字符串[]参数）
{
var servicecolection=新servicecolection（）；
serviceCollection.AddTransient（（IServiceProvider提供程序）=>
{
键入typeBeingResolved=？？？；//这是否回答了您的问题？
