问题
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!
回答1:
var routeValueDictionary = urlHelper.RequestContext.RouteData.Values;
use this with your custom context.
