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