我怎么有自定义字符串格式化为枚举值枚举绑定组合框？ [英] How do I have an enum bound combobox with custom string formatting for enum values?
问题描述
在 DescriptionAttribute 是这样的：
In the post Enum ToString, a method is described to use the custom attribute DescriptionAttribute like this:
Enum HowNice {
[Description("Really Nice")]
ReallyNice,
[Description("Kinda Nice")]
SortOfNice,
[Description("Not Nice At All")]
NotNice
}
然后，你调用一个函数 GetDescription ，使用的语法如下：
GetDescription<HowNice>(NotNice); // Returns "Not Nice At All"
但是，这并不真正帮助我的时，我想简单地填充枚举的值的组合框，因为我不能强迫组合框调用 GetDescription
But that doesn't really help me when I want to simply populate a ComboBox with the values of an enum, since I cannot force the ComboBox to call GetDescription.
我想有以下要求：
- 阅读
（HowNice）myComboBox.selectedItem将返回选定的值作为枚举值。 - 用户应该看到用户友好的显示字符串，而不仅仅是枚举值的名称。因此，而不是看到
NotNice，用户将看到不是很好。在所有 - 我们希望，该解决方案将需要最少code更改现有枚举。
- Reading
(HowNice)myComboBox.selectedItemwill return the selected value as the enum value. - The user should see the user-friendly display strings, and not just the name of the enumeration values. So instead of seeing "
NotNice", the user would see "Not Nice At All". - Hopefully, the solution will require minimal code changes to existing enumerations.
显然，我可以实现的，我创建的每个枚举一个新的类，并覆盖其的ToString（），但这是每个枚举了大量的工作，我宁愿避免这种情况。
Obviously, I could implement a new class for each enum that I create, and override its ToString(), but that's a lot of work for each enum, and I'd rather avoid that.
任何想法？
哎呀，我甚至会扔在一个<一个href=\"http://stackoverflow.com/questions/795979/retrieve-a-list-of-the-most-popular-get-param-variations-for-a-given-url\">hug作为赏金： - ）
Heck, I'll even throw in a hug as a bounty :-)
推荐答案
您可以编写一个读取指定的属性，看看他们在你的资源的类型转换器。因此，你会得到的显示名称多语言支持，没有什么麻烦。
You could write an TypeConverter that reads specified attributes to look them up in your resources. Thus you would get multi-language support for display names without much hassle.
看到的TypeConverter的ConvertFrom /的ConvertTo方法，并使用反射来在你的阅读枚举属性的字段的
Look into the TypeConverter's ConvertFrom/ConvertTo methods, and use reflection to read attributes on your enum fields.
