如果子类型是父类型

Question

I am trying to pass a an inherited class type in to a method and want to check if the type is a type of base class. How can I do this, since inherited.GetType() == typeof(baseclass) will return false?

Answer 1

The is operator does this.

if (inherited is baseclass)
{
    // do stuff
}

You could also use Type.BaseType if you want to know that it is exactly the direct parent.

Answer 2

您也可以使用Type.IsSubclassOf

inherited.GetType().IsSubclassOf(typeof(Base));

Answer 3

Use Type.IsAssignableFrom :

if (typeof(baseclass).IsAssignableFrom(inh.GetType())
{
...
}
