是否有可能有条件地隐藏在编译时在.NET属性？ [英] Is it possible to conditionally hide properties at compile time in .Net?

问题描述

根据一个preprocessor指令，我想在一个类来EditorBrowsableAttribute.Never设置的所有属性。

Depending on a preprocessor directive, I want to set all properties in a class to EditorBrowsableAttribute.Never.

我想到了创建一个自定义属性，从EditorBrowsableAttribute来源，但不幸的是这个类是密封的。

I thought about creating a custom attribute, derived from EditorBrowsableAttribute, but unfortunately that class is sealed.

我看了一下ICustomTypeDescriptor，但在getProperties方法，我可以掌握每个属性描述的，但属性集合是只读的。

I've had a look at ICustomTypeDescriptor, but in the GetProperties method, I can get hold of each property descriptor, but the attributes collection is readonly.

任何想法？

推荐答案

我发生过这个问题，最近又和这一次的答案来找我非常迅速;简单地设置了一些常量：

I happened across this issue again recently and this time the answer came to me very quickly; simply set up a couple of constants:

Friend Class CompilerUtils

#If HideCode Then
    Public Const Browsable As EditorBrowsableState = EditorBrowsableState.Never 
    Public Const BrowsableAdvanced As EditorBrowsableState = EditorBrowsableState.Never 
#Else
    Public Const Browsable As EditorBrowsableState = EditorBrowsableState.Always
    Public Const BrowsableAdvanced As EditorBrowsableState = EditorBrowsableState.Advanced
#End If

End Class

然后在你的code，装点一员，像这样：

Then in your code, decorate a member like so:

<EditorBrowsable(CompilerUtils.Browsable)> _
<EditorBrowsable(CompilerUtils.BrowsableAdvanced)> _
