C#如何检查类是否实现了通用接口？

Question

如何获取实例的通用接口类型？

假设这段代码:

interface IMyInterface<T>
{
    T MyProperty { get; set; }
}
class MyClass : IMyInterface<int> 
{
    #region IMyInterface<T> Members
    public int MyProperty
    {
        get;
        set;
    }
    #endregion
}


MyClass myClass = new MyClass();

/* returns the interface */
Type[] myinterfaces = myClass.GetType().GetInterfaces();

/* returns null */
Type myinterface = myClass.GetType().GetInterface(typeof(IMyInterface<int>).FullName);

Answer 1

要获取通用接口,您需要使用Name属性而不是FullName属性:

MyClass myClass = new MyClass();
Type myinterface = myClass.GetType()
                          .GetInterface(typeof(IMyInterface<int>).Name);

Assert.That(myinterface, Is.Not.Null);
