可能访问子级“调试器显示”属性属性？ [英] Possible to accessing child "DebuggerDisplay" attribute of property?

问题描述

当前状态

有两个课程：

 code> [DebuggerDisplay（@One = {One}，two = {Two}）] 
 public class A 
 {
 public int One {get;组; } 
 public B Two {get;组; } 
} 
 
 [DebuggerDisplay（@Three = {Three}）] 
 public class B 
 {
 public int Three {get;组; } 
} 
  

使用它们：

  var a = new A {One = 5，Two = new B {Three = 10}}; 
  

调试器内的工具提示值显示在 a

One = 5，two = {DebuggerDisplayTest.B}

目标

我想要的是像

One = 5，two ='Three = 10'

我知道这可以通过覆盖类 B 的 ToString（）方法来实现。这只是感觉不正确，因为我正在我的应用程序中编写代码进行调试。

我也知道使用类似于

$ b $的字符串b

  [DebuggerDisplay（@One = {One}，two ='Three = {Two.Three}'）] 
  

也可以工作。这也不适合我，因为它将需要类 A 具有类 B 的知识。 p>

我想要更多的方法来注入 B 中的类别 DebuggerDisplay 的类型的实例$ c> A 。

问题

是否可以访问$$code> DebuggerDisplay 属性的 DebuggerDisplay 属性的 DebuggerDisplay 属性的has-a课程？

更新

可能我的要求是不可能的， a href =http://stackoverflow.com/a/258961/107625>此SO答案。也许一个很好的解决方案是在课程 B 中覆盖 ToString ，并执行一些如果.. else 并使用 调试器.IsAttached 属性只在调试器内部行为不同。

如下所示：

  [DebuggerDisplay（@Three = {Three}）] 
 public class B 
 {
 public int Three {get;组; } 
 
 public override string ToString（）
 {
 if（Debugger.IsAttached）
 {
 return string.Format（@Three = {0 }，三）; 
} 
 else 
 {
 return base.ToString（）; 
} 
} 
} 
  

解决方案

从OP复制可能的解决方案

可能我的要求是不可能的，因为这个SO回答。也许一个很好的解决方案是覆盖B类中的ToString，并执行一些if..else，并使用 Debugger.IsAttached property 只在调试器内部行为不同。

如下：

  [DebuggerDisplay（@Three = {Three}）] 
 public class B 
 {
 public int Three {get;组; } 
 
 public override string ToString（）
 {
 if（Debugger.IsAttached）
 {
 return string.Format（@Three = {0 }，三）; 
} 
 else 
 {
 return base.ToString（）; 
} 
} 
} 
  

Current state

Having two classes:

[DebuggerDisplay(@"One = {One}, two = {Two}")]
public class A
{
    public int One { get; set; }
    public B Two { get; set; }
}

[DebuggerDisplay(@"Three = {Three}")]
public class B
{
    public int Three { get; set; }
}

Using them:

var a = new A {One = 5, Two = new B {Three = 10}};

Inside the debugger, the tool tip value that is displayed at a is

One = 5, two = {DebuggerDisplayTest.B}

Goal

What I would want is something like

One = 5, two = 'Three = 10'

I know this could be achieved by overriding the ToString() method of class B. This just feels not right, since I'm writing code in my application for debugging only.

I also know that using a string similar to

[DebuggerDisplay(@"One = {One}, two = 'Three = {Two.Three}'")]

would work, too. This also does not feel right to me, since it would require that class A has knowledge of class B.

I would like to have more of a way to "inject" the value of DebuggerDisplay of type B to the instance of that type in class A.

Question

Is it somehow possible to access the DebuggerDisplay attribute of a member inside the DebuggerDisplay attribute of a "has-a" composited class?

Update

Probably, my requirement is not possible as per this SO answer. Maybe a good solution would be to override ToString in class B and do some if..else and use the Debugger.IsAttached property to behave different only inside the debugger.

Something like:

[DebuggerDisplay(@"Three = {Three}")]
public class B
{
    public int Three { get; set; }

    public override string ToString()
    {
        if (Debugger.IsAttached)
        {
            return string.Format(@"Three = {0}", Three);
        }
        else
        {
            return base.ToString();
        }
    }
}
