属性名称作为属性构造函数的输入 [英] Name of a property as input to attribute constructor

问题描述

我有一个自定义属性，我希望它具有一个属性名称作为输入.因为名称是一个字符串，所以它是有效的输入类型(因为属性对于它们作为构造函数的输入所具有的限制非常有限). 但是我该怎么做呢?

I have a custom attribute and I would like it to have the name of a property as input. Because the name is a string it is a valid input type (as attributes are quite limited as to what they can have as input to their constructors). But how can I accomplish this?

使用以下示例代码:

public class MyCustomAttribute : Attribute {
    public MyCustomAttribute(string propertyName) {}
}

public class Foo {
    public bool MyCustomProperty { get; set; }

    [MyCustom(SomeMagicAppliedToMyCustomProperty)] // I want the attribute to receive something along the lines of "Foo.MyCustomProperty"
    public void Bar();
}

我该如何限制属性在其构造函数中可以接收的内容?

How can I accomplish this with the limitations to what an attribute can receive in its constructor?

推荐答案

这是不可能的. 这些属性只能接受常量，只需将MyCustomProperty名称用引号引起来即可.

This is not possible. The attributes can accept only constants, just put your MyCustomProperty name in quotes into the Attribute.
