c# - 封闭式与开放式比较

Question

我很好奇如何检查给定类型是否是开放类型的封闭版本。例如

public bool IsGenericList(Type source)
{
    return (source.IsGenericType &&
            /*here goes the manipulation on source type*/ == typeof(List<>));
}

Answer 1

尝试 Type.GetGenericTypeDefinition :

public bool IsGenericList(Type source)
{
    return source.IsGenericType &&
           source.GetGenericTypeDefinition() == typeof(List<>);
}
