i want retrieve route values from RouteTable, but it's null. can anybody help?
public static class GetRouteValues
{
public static string GetSomeValue()
{
RouteCollection routes = RouteTable.Routes;
var value = routes["somevalue"].ToString();
return value;
}
}
i want retrieve this value for using in global.asax file and set as default value for some routes value.
string value = GetRouteValues.GetSomeValue();
routes.MapRoute(开发者_如何学JAVAnull,
"{_value}/home",
new
{
_value = value,
controller = "home",
action = "index"
});
Ok if you are trying to get the current route, you can do this from within a controller....
var completeRoute = this.ControllerContext.RouteData.Route;
//or
var justValue = this.ControllerContext.RouteData.Values["value"]
Let me know if thats what you are after...
UPDATE:
Ok I think this should do what you are after. You should be able to use this in a static method without passing in any context object.
var httpContext = new HttpContextWrapper(HttpContext.Current);
var requestContext = new RequestContext(httpContext, new RouteData());
var completeRoute = requestContext.RouteData.Route;
var justValue = requestContext.RouteData.Values["value"];
Hope that helps.
I used anthonyv's answer for my static class but the results were null. The following worked for me (similar to how to access Session objects in a static class).
var controller = HttpContext.Current.Request.RequestContext.RouteData.Values["controller"];
var action = HttpContext.Current.Request.RequestContext.RouteData.Values["action"];
Global would be nice, but so far I've only seen it within Controller:
Namespace Controllers
Public Class HomeController
Inherits BaseController
Dim routeValues = System.Web.HttpContext.Current.Request.RequestContext.RouteData.Values
Dim actionName As String
Dim controllerName As String
Public Function Index(id As String) As ActionResult
Try
Dim x As Integer = 0
Dim y As Integer = 5
Dim z As Integer = y / x
Catch ex As Exception
If routeValues IsNot Nothing Then
If routeValues.ContainsKey("action") Then
actionName = routeValues("action").ToString()
End If
If routeValues.ContainsKey("controller") Then
controllerName = routeValues("controller").ToString()
End If
End If
Log.LogError(ex, controllerName, actionName)
End Try
