why action parameter converts to query string in asp net core

Question

I have this method in ASP.NET Core:

   [HttpDelete("id:int")]
    public async Task<IActionResult> Delelte(int id)
    {
       // do sth
    }

Now when I call this api via swagger the generated url is :

https://localhost:44357/api/mycontroller/id:int?id=2

I expected to have a url without querystring like api/mycontroller/2

The problem is that I want to call this api from code and in code I call it like this api/mycontroller/2 but it return 404

[HttpDelete("id:int")]

Should be

[HttpDelete("{id:int}")]

The parameters are encapsulated in angle brackets {} with optional constraints like int. Everything outside of that is considered a static part of the route url.

The issue seems to come from the way you have fromatted your HttpDelete attribute.

Try to format it this way instead :

[HttpDelete("{id}")]
