Question

在我的一个班子的施工人员中,我叫一名虚拟成员。是否应该或不应该这样做,是我的问题的范畴。

WORKS (can call in my constructor):

 protected void DoSomething();
 protected virtual void DoSomething();

DOES NOT 工作

 protected override void DoSomething();

The DOES NOT 工作 part is located in the same library, the derived class has the same visibility, etc. As soon as I override the (virtual or abstract) DoSomething defined in class A in my Class B, I get a MissingMethodException as soon as the method is executed.

Does anyone have an idea why?

Answer 1

在大量偷窃、审判等之后,似乎在与这一定义的接口中使用了一类:

public interface IMyInterface<out TValueInterface>

It seems you cannot use covariant type parameters, otherwise you will get this exception.

详情见。

Answer 2

我认为,这是因为你以SDK第1号标子建立了该项目。

在一个新项目中再次ry笑,你也遇到了问题:-p !
