检查类是否派生自泛型类 [英] Check if a class is derived from a generic class

问题描述

我的项目中有一个带有派生类的泛型类.

I have a generic class in my project with derived classes.

public class GenericClass<T> : GenericInterface<T>
{
}

public class Test : GenericClass<SomeType>
{
}

有什么办法可以查明Type 对象是否是从GenericClass 派生的?

Is there any way to find out if a Type object is derived from GenericClass?

t.IsSubclassOf(typeof(GenericClass<>))

不起作用.

推荐答案

试试这个代码

static bool IsSubclassOfRawGeneric(Type generic, Type toCheck) {
    while (toCheck != null && toCheck != typeof(object)) {
        var cur = toCheck.IsGenericType ? toCheck.GetGenericTypeDefinition() : toCheck;
        if (generic == cur) {
            return true;
        }
        toCheck = toCheck.BaseType;
    }
    return false;
}
