检查类是否是特定泛型的子类

下面的函数检查您的类的子类是否与提供的类类型相同。如果类型是泛型的,则对泛型类型定义执行检查操作。

方法使用

bool isInherited = CheckIsDirectlyInherited(typeof(TestAbstract), new[] {typeof(SecondLevelAbstractClass), typeof(FirstLevelAbstract)});

方法

bool CheckIsDirectlyInherited(Type obj, Type[] baseTypes)
{
    if (obj.BaseType == null)
        return false;

    var objGenericDefinition = obj.BaseType;
    if (objGenericDefinition.IsGenericType)
    {
        objGenericDefinition = objGenericDefinition.GetGenericTypeDefinition();
    }

    foreach (Type baseType in baseTypes)
    {
        var baseTypeDefinition = baseType;
        if (baseTypeDefinition.IsGenericType)
            baseTypeDefinition = baseType.GetGenericTypeDefinition();

        if (objGenericDefinition == baseTypeDefinition)
            return true;
    }

    return false;
}

是HtSecurePage的直接子类

Console.WriteLine(typeof(HtSecureInstancePage<ZlsManager>).BaseType == typeof(HtSecurePage));

是HtSecureInstancePage的直接子类<>

static bool IsDirectSubclassOfRawGeneric(Type parent, Type toCheck)
{
    return toCheck.BaseType.IsGenericType && parent == toCheck.BaseType.GetGenericTypeDefinition();
}
...
Console.WriteLine(IsDirectSubclassOfRawGeneric(typeof(HtSecureInstancePage<>), typeof(InstancePage)));
