c# - 我可以在接口(interface)方法中检索接口(interface)类型吗？

Question

如何确定从中调用方法 DoSomething() 的底层接口(interface)？附加问题:我是否已经确定了 MyClass 构造函数中的底层接口(interface)？我假设不是，因为它在实例化时是未知的，对吗？

编辑:我不是在寻找显式接口(interface)实现，而是在寻找确定底层接口(interface)的不同方法。

public interface ITest
{
    void DoSomething();
    //....more methods
}

public interface IDecoy
{
    void DoSomething();
    //...more methods
}

public class MyClass : ITest, IDecoy
{
    public void DoSomething()
    {
        //Question: How can I determine the underlying interface that called this method?
        //at one time it is ITest, at another IDecoy. How can I figure out which one at each time?
    }
}

public class Test
{
    public Test()
    {
        ITest myClassInstance1 = new MyClass();
        IDecoy myClassInstance2 = new MyClass();

        myClassInstance1.DoSomething();
        myClassInstance2.DoSomething();
    }
}

Answer 1

public class MyClass : ITest, IDecoy
{
    void ITest.DoSomething()
    {
        //called with ITest 
    }
    void IDecoy.DoSomething()
    {
        //called with IDecoy 
    }
}
