Consuming xml using HttpClient from webapi

Question

I used WebClient to get an Xml object from a restfull service (.net web api) and everything worked great:

using(WebClient client = new WebClient())
{
   client.Encoding = UTF8Encoding.UTF8;
   client.Headers[HttpRequestHeader.ContentType] = "text/xml";
   client.Credentials = // ....;
   xmlResult = webClient.DownloadString(url);
}

....

this code works great. I get an Xml as a string back, everyone's happy.

Now, I changed it so it would work with HttpClient instead and I can't get an Xml returned - always a json as a string.

using(var handler = new HttpClientHandler() {Credentials = new NetworkCredentials})
using(var client = new HttpClient(handler))
{
   var request = new HttpRequestMessage(HttpMethod.Get, url);
   request.Headers.Add(HttpRequestHeader.ContentType.ToString(), "text/xml");
   returnedXml = client.SendAsync(request).Result.Content.ReadAsStringAsync().Result;
}

What am I doing wrong? How can I get the Xml I long for?

Thanks

Just Try this one ..

using(var handler = new HttpClientHandler() {Credentials = new NetworkCredentials})
using(var client = new HttpClient(handler))
{
      client.DefaultRequestHeaders
      .Accept
      .Add(new MediaTypeWithQualityHeaderValue("text/xml"));
   var request = new HttpRequestMessage(HttpMethod.Get, url);
    returnedXml = client.SendAsync(request).Result.Content.ReadAsStringAsync().Result;
}

It's so weird that it won't work if you have BaseAddress already set up and you're trying to do that via GetAsync("/") you need to specify the URL in GetAsync, lol

Figured it out!

I should have added a Accept header and its type should be "application/xml".

The working version:

using(var handler = new HttpClientHandler() {Credentials = new NetworkCredentials})
using(var client = new HttpClient(handler))
{
  var request = new HttpRequestMessage(HttpMethod.Get, url);
  request.Headers.Add(HttpRequestHeader.Accept.ToString(), "application/xml");
  returnedXml = client.SendAsync(request).Result.Content.ReadAsStringAsync().Result;
}

Refactored version of the existing answers here,

using var client = new HttpClient();
client
    .DefaultRequestHeaders
    .Accept.Add(new MediaTypeWithQualityHeaderValue(MediaTypeNames.Text.Xml));
client.Timeout = TimeSpan.FromSeconds(500);
var response = await client.GetAsync("Put your URL right here!");
if (response.IsSuccessStatusCode)
{
    var responseContent = await response.Content.ReadAsStringAsync();
    if (string.IsNullOrWhiteSpace(responseContent) == false)
// etc etc etc
