So, Route Constraints make certain that a route will only be picked When the parameters while in the URL fulfill specific disorders. This assists in:
The next code prevents the namespace Conference from staying placed on controllers which can be attribute routed:
Distinction the previous code with the traditional default route, which defines the id parameter as optional ( id? ). The opportunity to exactly specify APIs has advantages, for example letting /solutions and /merchandise/five to generally be dispatched to distinct actions.
If you won't deliver any of your values then the default values of those parameters will likely be provided by the routing process. Here is an index of URLs that match and don't match this route sample.
Route constraints are Utilized in equally attribute-based mostly and standard-primarily based routing to make certain that the values supplied within the URL match the expected details forms or formats. Allow’s say we want to produce a route matching the next URLs.
Steps that determine attribute routes can't be attained by the traditional routes and vice-versa. Any route attribute about the controller can make all actions during the controller attribute routed.
Attribute routing utilizes a list of characteristics to map actions straight to route templates. The following StartUp.Configure code is common for the REST API and is Employed in another sample:
Default and optional route parameters don't need to be current within the URL route for any match. See Route Template Reference for an in depth description of route template syntax.
The route values for controller and motion typically appear in that template. This is effective since the URLs matched by routing adhere to a convention.
Even so if want to use a particular route to crank out the URL we can use the RouteLink HTML helper. An instance is demonstrated down below

Take note: The route title ought to be one of a kind over the whole software. Route name can’t be duplicated.
