C# 动态属性参数

C# Dynamic Attribute Arguments(C# 动态属性参数)

问题描述

有没有办法做到以下几点?我看到属性参数必须是一个常量表达式，那么我将如何解决这个问题?如果我不想使用绑定将 一些 属性加载到 datagridview 中，那么下一个最佳选择是什么?

Is there a way to do the following? I see that the Attribute Arguments must be a constant expression, so how would I work around this? If I dont want to load some properties into a datagridview using binding, whats the next best alternative?

  class TestObj
  {
     private bool isBrowsable = false;

     [Browsable(isBrowsable)]
     public string String1
     {
        get
        {
           return "Foo";
        }
     }
     [Browsable(isBrowsable)]
     public string String2
     {
        get
        {
           return "Baz";
        }
     }
  }

推荐答案

您可以通过实现 ICustomTypeDescriptor 接口 - 但这是一项相当多的工作，并不像用属性装饰属性那么简单.

You can provide dynamic custom type information at runtime by implementing the ICustomTypeDescriptor interface - but this is quite a bit of work at not nearly as simple as decorating properties with attributes.
