Answer 1

JaredPar's code works but only for one level of inheritance. For unlimited levels of inheritance, use the following code

public bool IsTypeDerivedFromGenericType(Type typeToCheck, Type genericType)
{
    if (typeToCheck == typeof(object))
    {
        return false;
    }
    else if (typeToCheck == null)
    {
        return false;
    }
    else if (typeToCheck.IsGenericType && typeToCheck.GetGenericTypeDefinition() == genericType)
    {
        return true;
    }
    else
    {
        return IsTypeDerivedFromGenericType(typeToCheck.BaseType, genericType);
    }
}
