RouteValueDictionary Constructor (Object)

RouteValueDictionary Constructor (Object)

Initializes a new instance of the RouteValueDictionary class and adds values that are based on properties from the specified object.

Namespace:  System.Web.Routing
Assembly:  System.Web (in System.Web.dll)

public RouteValueDictionary(
	Object values


Type: System.Object
An object that contains properties that will be added as elements to the new collection.

Every key in a RouteValueDictionary object must be unique according to the dictionary's equality comparer. The RouteValueDictionary class uses case-insensitive ordinal comparison. For more information, see OrdinalIgnoreCase. A key cannot be null.

The following example shows how to create a Route object and how to set the Constraints, DataTokens, and Defaults properties.

void Application_Start(object sender, EventArgs e) 

public static void RegisterRoutes(RouteCollection routes)
    Route reportRoute = new Route("{locale}/{year}", new ReportRouteHandler());
    reportRoute.Defaults = new RouteValueDictionary { { "locale", "en-US" }, { "year", DateTime.Now.Year.ToString() } };
    reportRoute.Constraints = new RouteValueDictionary { { "locale", "[a-z]{2}-[a-z]{2}" }, { "year", @"\d{4}" } };
    reportRoute.DataTokens = new RouteValueDictionary { { "format", "short" } };
