c# - 覆盖继承字段的属性

Question

假设我有一个类:

abstract class MyBaseClass {

   [Attribute1]
   [Attribute2]
   public string Property1 {get; set; }

   [Attribute3]
   [Attribute4]
   public string Property2 {get; set; }
}

在扩展此类的子类中，我想向 Property1 和 Property2 添加新属性，保留在父类中声明的属性。

这可能吗？

Answer 1

abstract class MyBaseClass {

   [Attribute1]
   [Attribute2]
   public virtual string Property1 {get; set; }

   [Attribute3]
   [Attribute4]
   public virtual string Property2 {get; set; }
}

class NewClass:MyBaseClass
{
  [Attribute5]
  public override string Property1 {get;set;}

  [Attribute6]
  public override string Property2 {get;set;}
}

确保属性 1-4 使用 inherited = true

[AttributeUsage(AttributeTargets.Property, Inherited = true)]
public class Attribute1 : Attribute
{
}
