How to use credentials in HttpClient in c#?

Question

I am facing some problems when using the HttpClient class to access to a Delicious API. I have the following code:

try
{
    const string uriSources = \"http

I had the exact same problem myself. It seems the HttpClient just disregards the credentials set in the HttpClientHandler.

The following shall work however:

using System.Net.Http.Headers; // For AuthenticationHeaderValue

const string uri = "https://example.com/path?params=1";
using (var client = new HttpClient()) {
    var byteArray = Encoding.ASCII.GetBytes("MyUSER:MyPASS");
    var header = new AuthenticationHeaderValue(
               "Basic", Convert.ToBase64String(byteArray));
    client.DefaultRequestHeaders.Authorization = header;

    var result = await client.GetStringAsync(uri);
}

No need for the handler.
