IRouteConstraint IRouteConstraint IRouteConstraint IRouteConstraint Interface

Definition

Defines the contract that a class must implement in order to check whether a URL parameter value is valid for a constraint.

public interface class IRouteConstraint
public interface IRouteConstraint
type IRouteConstraint = interface
Public Interface IRouteConstraint
Derived

Remarks

When you include a constraint for a URL parameter in a route definition, you must represent the constraint as either string or as an object that implements the IRouteConstraint interface. If the constraint is a string, it is treated as a regular expression. You create a class that implements IRouteConstraint when you cannot represent the validation logic easily as a regular expression. You add the validation logic in the Match method.

Methods

Match(HttpContextBase, Route, String, RouteValueDictionary, RouteDirection) Match(HttpContextBase, Route, String, RouteValueDictionary, RouteDirection) Match(HttpContextBase, Route, String, RouteValueDictionary, RouteDirection) Match(HttpContextBase, Route, String, RouteValueDictionary, RouteDirection)

Determines whether the URL parameter contains a valid value for this constraint.
