The URL pattern is considered only after the area identify part within the URL. As an example, the URL pattern " controller / action / id " would look like localhost:1234/ controller / motion / id .

To achieve this, we will configure the MapControllerRoute process, as shown in the picture under. Below, you are able to see We now have specified the pattern as Student/All as well as default controller and action identify as controller = University student, motion = Index.

Contrast the previous code with the traditional default route, which defines the id parameter as optional ( id? ). A chance to exactly specify APIs has pros, for example letting /goods and /products and solutions/5 to get dispatched to various actions.

Attribute routes support the same inline syntax as regular routes to specify optional parameters, default values, and constraints.

Default and optional route parameters needn't be current inside the URL path for a match. See Route Template Reference for an in depth description of route template syntax.

That is Functioning fantastic. But, the situation with the above mentioned route is that it can accept any value. As an alternative to an integer, should you pass a string benefit, Furthermore, it accepts and executes the action strategies, as shown below.

The ControllerBase and Controller base courses present usefulness approaches for action success that reference A different action. 1 usual utilization is always to redirect following accepting person input:

Step 5 − Alter the return variety from ActionResult to string as well as return some string from this motion technique applying the following code.

With attribute routing, the controller and motion names play no part by which action is matched, Unless of course token replacement is utilized. The following example matches exactly the same routing in asp.net mvc URLs because the prior example:

Token replacement takes place as the final action of making the attribute routes. The preceding case in point behaves similar to the subsequent code:

URL era fails if any required route parameter does not have a corresponding value. If URL era fails to get a route, the next route is experimented with till all routes are actually attempted or simply a match is located.

This is useful for sustaining constant behavior and reducing the necessity to specify each individual parameter during the URL explicitly.

The GetIntProduct motion is made up of the "int/ id:int " template. The :int portion of the template constrains the id route values to strings that can be transformed to an integer. A GET request to /api/test2/int/abc: Doesn't match this motion.

Default values indicate if you won't deliver the values with the controller or action or ID outlined from the pattern then these values is going to be served via the routing program.
