C# HttpClient - How to send a Delete request with or without a body

Using the HttpRequestMessage together with the HttpClient you can easily send a HTTP Delete request in C#. Below we have a delete endpoint on https://localhost:7210/{id} where we provide the id "123" as the resource we want to delete:

var httpClient = new HttpClient();

var request = new HttpRequestMessage(HttpMethod.Delete,   
var response = httpClient.Send(request);

In the above we make a new HttpClient and a HttpRequestMessage with the HttpMethod Delete. We then use the basic Send() method on the HttpClient to send this. There is nothing more to it.

Having a JSON body for the delete request

You can also make a delete request that has a body. Note: this might not always be the best idea, see this page for more information. Having a body for the request is a little more cumbersome as you need to create the JSON you want to send, below is an example:

var httpClient = new HttpClient();
var deleteObject = new
    Id = 123
var stringContent = new StringContent(
   JsonConvert.SerializeObject(deleteObject), Encoding.UTF8, 
var request = new HttpRequestMessage(HttpMethod.Delete, 
request.Content = stringContent;
var response = httpClient.Send(request);

In the above we create a new HttpClient and an anonymous object which will be the model for our request. We then use our anonymous object as input to a StringContent Object, the StringContent will be the body of the request and provide some headers such as the encoding (Encoding.UTF8) and content-type (application/json). As in the previous example we create a HttpRequestMessage the difference here is that we also provide it with "Content", which is our StringContent. In the end we call the Send() method on the HttpClient with our HttpRequestMessage.

Making a Delete endpoint in ASP.NET

I have written a short blog post on how to make endpoints for the above here. It shows how you can make a DELETE endpoint in ASP.NET with or without a body.

That is it
