Create Custom Methods in ASP Web API Controller and retrieve their data

Question

I Have a C# WinForms application and in a form I want to consume (Get) some data from an ASP Web API application.

in Web API I have a controller named Session inside this controller I have two methods as shown below :

        public int Create()
    {
        Random random = new Random();
        int New_ID = random.Next();
        return New_ID ;
    }
    public string Get()
    {
        return "Catch this data";
    }

So the problem is when I use browser URL (For testing) to access to controller (Session)

URL : http://localhost:52626/api/Session

I got

And when I want to access to controller (Session) especially Create Function

URL : http://localhost:52626/api/Session/Create

I got

The global question is how can I create my own methods and access to it without depending on Get ?

A URL you have client doing a Request and a getting back a Response. Your controller is a Server which accepts the request and returns the response. — jdweng

The browser always fires a GET. Web-API by default selects the method to be called using the HTTP verb (GET in your case) of request. Hence it always lands in "Get" method. To make Web-API point to your method you need to define a route. Use below:

        [Route("api/session/Create")]
        [HttpGet]
        public int Create()
        {
            Random random = new Random();
            int New_ID = random.Next();
            return New_ID;
        }

To better understand route based selection, read this : https://learn.microsoft.com/en-us/aspnet/web-api/overview/web-api-routing-and-actions/routing-and-action-selection
