Gets or sets the values to use if the URL does not contain all the parameters.

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

member Defaults : RouteValueDictionary with get, set

Property Value

Type: System.Web.Routing.RouteValueDictionary

An object that contains the parameter names and default values.

The Defaults property enables you to set the value for a URL parameter if the URL does not contain a segment for that parameter. You assign a RouteValueDictionary object to the Defaults property. Each element in the RouteValueDictionary object contains the name of a parameter and the value to use if the parameter is missing.

You can include a default value for a parameter that is not defined in the Url property as a segment. When ASP.NET routing handles a request, this default value is always passed to the route handler. When you construct a URL and you include a value for a default parameter that is not defined as a segment, the route will only be considered a match if the value that you provided matches the default value for the route.

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