如何使 MVC3 DisplayFor 显示枚举的显示属性的值? [英] How to make MVC3 DisplayFor show the value of an Enum's Display-Attribute?
问题描述
在 MVC3 项目中,我使用的是带有显示属性的枚举:
in a MVC3-Project, I'm using an enum with display-Attributes:
public enum Foo {
[Display(Name = "Undefined")]
Undef = 0,
[Display(Name = "Fully colored")]
Full = 1
}
模型类有一个使用这个枚举的属性:
The model class has a property using this enum:
public Foo FooProp { get; set; }
视图使用模型类并通过显示属性
The view uses the model class and displays the property via
@Html.DisplayFor(m => m.FooProp)
现在,最后,我的问题:
Now, finally, my question:
如何让 .DisplayFor() 显示来自 Display-Attribute 的字符串,而不是仅显示枚举的值名称?(它应该显示未定义"或全彩色",但显示未定义"或全彩色").
How can I make .DisplayFor() show the string from the Display-Attribute instead of showing only the enum's value-name? (it should show "Undefined" or "Fully colored", but displaysp "Undef" or "Full").
感谢您的提示!
推荐答案
自定义显示模板可能会有所帮助(~/Views/Shared/DisplayTemplates/Foo.cshtml
):
A custom display template might help (~/Views/Shared/DisplayTemplates/Foo.cshtml
):
@using System.ComponentModel.DataAnnotations
@model Foo
@{
var field = Model.GetType().GetField(Model.ToString());
if (field != null)
{
var display = ((DisplayAttribute[])field.GetCustomAttributes(typeof(DisplayAttribute), false)).FirstOrDefault();
if (display != null)
{
@display.Name
}
}
}
