mvc3，可以给控制器显示名称吗? [英] mvc3, can you give controller a display name?

问题描述

我正在使用mvc3.是否可以给控制器和动作一个显示名称.

I am using mvc3. is it possible to give controller and action a display name.

[DisplayName("Facebook Employee")]
public class EmployeeController : Controller

在我的面包屑中，我将获得控制器名称和操作名称

in my breadcrumb, I will get the controller name and action name

@{
var controllerName = ViewContext.RouteData.Values["Controller"];
var actionName = ViewContext.RouteData.Values["Action"];
}

我希望看到"Facebook雇员"，但是它不起作用.

I expect to see "Facebook Employee", but its not working.

推荐答案

您必须使用

You'll have to reflect on the Controller type itself, using GetCustomAttributes. Use ViewContext.Controller to get a reference to the controller itself. Something like this:

string controllerName;
Type type = ViewContext.Controller.GetType();
var atts = type.GetCustomAttributes(typeof(DisplayNameAttribute), false);
if (atts.Length > 0)
    controllerName = ((DisplayNameAttribute)atts[0]).DisplayName;
else 
    controllerName = type.Name;   // fallback to the type name of the controller

修改

要对操作执行类似操作，您需要先使用Type.GetMethodInfo反思该方法:

To do similar for an action, you need to first reflect on the method, using Type.GetMethodInfo:

string actionName = ViewContext.RouteData.Values["Action"]
MethodInfo method = type.GetMethod(actionName);
var atts = method.GetCustomAttributes(typeof(DisplayNameAttribute), false);
// etc, same as above
