什么的继承布尔的属性属性是指？

What does the Inherited bool property on attributes refers to?

这是否意味着，如果我有一个属性 AbcAtribute 定义我的类（即具有继承= TRUE ），如果我继承另一个类从该类，该派生类也将有相同的属性应用到它？

Does it mean that if I define my class with an attribute AbcAtribute (that has Inherited = true), and if I inherit another class from that class, that the derived class will also have that same attribute applied to it?

要澄清这个问题有code例如，想象一下以下内容：

To clarify this question with a code example, imagine the following:

[AttributeUsage(AttributeTargets.Class, Inherited = true)]
public class Random: Attribute
{ /* attribute logic here */ }

[Random]
class Mother 
{ }

class Child : Mother 
{ }

确实孩子也有随机属性应用到它？

Does Child also have the Random attribute applied to it?

推荐答案

在继承= TRUE这意味着你创建的属性可以通过子类的类的属性装饰的继承。

When Inherited = true it means that the attribute you are creating can be inherited by sub-classes of the class decorated by the attribute.

所以 - 如果你创建MyUberAttribute使用[AttributeUsage（继承= TRUE）]

So - if you create MyUberAttribute with [AttributeUsage (Inherited = true)]

[AttributeUsage (Inherited = True)]
MyUberAttribute : Attribute
{
   string _SpecialName;
   public string SpecialName
   { 
     get { return _SpecialName; }
     set { _SpecialName = value; }
   }
}

然后，通过装饰超一流的使用属性...

Then use the Attribute by decorating a super-class...

[MyUberAttribute(SpecialName = "Bob")]
class MySuperClass 
{
  public void DoInterestingStuf () { ... }
}

如果我们创建一个子类MySuperClass它都会有这样的属性...

If we create an sub-class of MySuperClass it will have this attribute...

class MySubClass : MySuperClass
{
   ...
}

然后实例MySubClass ...

Then instantiate an instance of MySubClass...

MySubClass MySubClassInstance = new MySubClass();

然后进行测试，看它是否具有属性...

Then test to see if it has the attribute...

MySubClassInstance＆LT; ---现在有MyUberAttribute与鲍勃作为SpecialName值

MySubClassInstance <--- now has the MyUberAttribute with "Bob" as the SpecialName value.
