To implement the DELETE method in ASP.NET Web API, you can follow these steps:
- Create a new controller method to handle the DELETE request. This method should be decorated with the
[HttpDelete]
attribute and accept an ID parameter. For example:
csharp[HttpDelete]
public IHttpActionResult DeleteEmployee(int id)
{
// Delete the employee from the database or perform other business logic
// ...
// Return a response indicating success
return Ok();
}
In the body of the method, you can perform any business logic required to delete the specified data. For example, you could delete the employee from a database or perform some other operation.
Return an appropriate response to indicate success or failure. In this example, we are returning an HTTP 200 OK response to indicate that the request was successful. You could also return a more specific response, such as an HTTP 204 No Content response, to indicate that the resource was deleted but there is no response body.
Note that the [HttpDelete]
attribute can also be used to specify the URL route for the DELETE request. By default, the method will be mapped to a URL that corresponds to the name of the controller method, but you can override this behavior by specifying a different route using the [Route]
attribute. For example:
csharp[HttpDelete]
[Route("api/employees/{id}")]
public IHttpActionResult DeleteEmployee(int id)
{
// ...
}
This would map the DELETE request to the URL "http://localhost/api/employees/{id}", where {id} is the ID of the employee to be deleted.
