类ASP.NET MVC C＃获取控制器和动作名称 [英] ASP.NET MVC C# Get controller and action name in class

问题描述

我是非常新的StackOverflow所以请原谅我的无知的迹象。 ：）

我有在Visual Studio 2010（C＃编写的控制器）MVC应用程序有点小问题。
我想创建它生成一个应用程序操作历史记录的方法，并为此目的我想获取在每一次使用的控制器和动作的名称。不幸的是持有我的控制器名称字符串的第一个字母总是缺少。
我用这个代码：

 字符串URL = HttpContext.Current.Request.RawUrl; 
的RouteData路线= RouteTable.Routes.GetRouteData（新OwnedContext（URL））; 
 VAR值= route.Values; 
串controllerName =值[控制器]的ToString（）; 
串actionName =值[行动]的ToString（）; 
  

在哪里OwnedContext是这样定义的：

 私有类OwnedContext：HttpContextBase 
 {
私人只读HttpRequestBase mockHttpRequestBase; 
 
公共OwnedContext（字符串appRelativeUrl）
 {
 this.mockHttpRequestBase =新OwnedRequest（appRelativeUrl）; 
} 
 
公众覆盖HttpRequestBase请求
 {
 {返回mockHttpRequestBase; } 
} 
} 
  

动作名称正确保存，但是当我调试这个代码我看到controllerName字符串持有控制器，但第一个（资本）的来信总是缺少的名字，即使URL字符串持有这种模式的值：/控制器/动作。

我会明白任何指针，代码示例或者解释为什么会这样。如果我的描述是不准确的让我知道，我会改进

在此先感谢：）

编辑：溶液中发现的：

发现问题（排序）：有什么问题OwnedContext（在我原来的问题定义）。起初，我用routeValueDictionary作为HarHaHu建议，但原来的问题依然存在，直到我把HttpContext的是GetRouteData的参数：

 字符串URL =的HttpContext .Current.Request.RawUrl; 
的RouteData路线= RouteTable.Routes.GetRouteData（HttpContext的）; 
 UrlHelper urlHelper =新UrlHelper（新的RequestContext（HttpContext的，路线））; 
 
 VAR routeValueDictionary = urlHelper.RequestContext.RouteData.Values; 
串controllerName = routeValueDictionary [控制器]的ToString（）; 
串actionName = routeValueDictionary [行动]的ToString（）; 
  

在哪里的HttpContext有一个自定义的getter：

 公开新HttpContextBase的HttpContext 
 {
得到
 {
 HttpContextWrapper背景= 
新HttpContextWrapper（System.Web.HttpContext.Current ）; 
回报（HttpContextBase）范围内; 
} 
} 
  

这样，我省略了OwnedContext终于拿到了我的控制器全名（例如：家具，而不是urniture）。

感谢您的提示。 :)
希望这可以帮助别人。祝你好运！

解决方案

  VAR routeValueDictionary = urlHelper.RequestContext.RouteData.Values; 
  

与您的自定义背景下使用此功能。

I'm pretty much new to StackOverflow so please forgive any signs of my ignorance. :)

I have a somewhat minor issue with an MVC application in Visual Studio 2010 (Controllers written in C#). I want to create a method which generates an application action history and for that purpose I want to get the name of the controller and action that are used each time. Unfortunately the first letter of the string which holds my controller name is always missing. I used this code:

    string url = HttpContext.Current.Request.RawUrl;
    RouteData route = RouteTable.Routes.GetRouteData(new OwnedContext(url));
    var values = route.Values;
    string controllerName = values["controller"].ToString();
    string actionName = values["action"].ToString();

Where OwnedContext is defined like this:

    private class OwnedContext : HttpContextBase
    {
        private readonly HttpRequestBase mockHttpRequestBase;

        public OwnedContext(string appRelativeUrl)
        {
            this.mockHttpRequestBase = new OwnedRequest(appRelativeUrl);
        }

        public override HttpRequestBase Request
        {
            get { return mockHttpRequestBase; }
        }
    }

The action name is stored correctly but when i debug this code i see that the controllerName string holds the name of the controller but the first (Capital) letter is always missing, even though the url string holds a value with this pattern: /controller/action.

I will appreciate any pointers, code examples or an explanation why this happens. If my description is not accurate let me know, I will improve it.

Thanks in advance :)

EDIT: SOLUTION FOUND:

Found the problem (sort of): There was something wrong with OwnedContext (defined in my original question). At first I used routeValueDictionary as HarHaHu suggested but the original problem persisted, until I placed httpContext as GetRouteData's parameter:

    string url = HttpContext.Current.Request.RawUrl;
    RouteData route = RouteTable.Routes.GetRouteData(httpContext);
    UrlHelper urlHelper = new UrlHelper(new RequestContext(httpContext, route));

    var routeValueDictionary = urlHelper.RequestContext.RouteData.Values;
    string controllerName = routeValueDictionary["controller"].ToString();
    string actionName = routeValueDictionary["action"].ToString();

Where httpContext has a custom getter:

    public new HttpContextBase httpContext
    {
        get
        {
            HttpContextWrapper context =
                new HttpContextWrapper(System.Web.HttpContext.Current);
            return (HttpContextBase)context;
        }
    }

This way I omitted the OwnedContext and finally got my controller's full name (for example: Furniture and not urniture).

Thanks for the tips. :) Hope this helps someone. Good luck!

解决方案

var routeValueDictionary = urlHelper.RequestContext.RouteData.Values;

use this with your custom context.
