如何创建自己的c＃属性？ [英] How to create my own c# attributes?

问题描述

MVC验证器，如必填字段等......它们是c＃属性吗？



我正在学习C＃属性，我有一个疑问，MVC验证器是否是属性的例子或不 ？我认为它们是。

因为我学到了属性是为了元素的描述。我们可以创建自定义属性，可以为元素（方法，类等）提供描述。根据我的理解，这是属性的用户。那是对的吗？属性是否还有其他用途？

如果MVC要求提交验证器是一个属性，它是如何工作的？我的意思是代码是如何在atribute中编写的。它不仅仅是提供帮助信息，那么它是如何工作的？

MVC validators like required field etc..are they c# attributes?

I was learning C# attributes, I have one doubt that whether MVC validators are example of attributes or not ? I think they are.
As i learned attributes are for description of element. We can create custom attributes which can give description for a element(method,class etc.) This is the us of attributes as per my understanding. Is that correct? Is there any other use for attributes?
If MVC require filed validator is a attribute how does that works? i mean how the code has written in atribute.It is doing more than providing help information so how is that works ?

您可以创建自己的自定义属性。通常，数据注释是根据您的需求定制的。
