The first URL is a route parameter used in MVC and Web API.  The the second is query string.

This is a fundamental concept.   Over the last several months, the community has tried many times to explain the fundamentals.  Yet, you continue to ask the same basic questions over and over.  I recommend that you take a class or find a way to set aside time to educate yourself.  Otherwise we cannot answer your question because clearly you do not understand the answers.

Hi,

Not 100% clear. It seems you are looking for https://www.tutorialsteacher.com/webapi/implement-delete-method-in-web-api

I would not return this as part of the response as you just deleted the resource (so anyway you would have a 404 if trying to use the url). It makes sense when CREATING a resource so that someone consuming your API knows which url to use to retrieve the newly created resource.

If it doesn't help please be a bit more explicit (for now my understanding is that you are trying to send back the location for the resource you just deleted as part of a DELETE request ??? but it's really rather a guess).

I want to consume this webapi and delete record.

If this is a programming problem, post source code that reproduces the problem.  Explain the expected results and actual results,

Otherwise the openly published Web API documentation covers this subject extensively.

How to do in httpresponsemessage

The following sample for your reference.

WebApiConfig:

            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );

Controller:

        // DELETE api/values/67
        // DELETE api/values?id=67
        public void Delete(int id)
        {
            Console.WriteLine(id);

        }

Method:

using (var client = new System.Net.Http.HttpClient())
            {
                var baseUrl = Request.Url.GetLeftPart(UriPartial.Authority);
                client.BaseAddress = new Uri(baseUrl);
                //var response = client.DeleteAsync("/api/Values/67").Result;
                var response = client.DeleteAsync("/api/Values?id=67").Result;
                string s = await response.Content.ReadAsStringAsync();
            }

Best Regards

Httpresponsemessage res;
res= client.deleteasync(/API/employee/1066).result
500 internal error

500 internal error

Hi,

It means you have a server side exception more likely in your controller. By default you should find error details in the Windows event log which should allow to understand which error you have and then how to fix this error.
