            client.DefaultRequestHeaders.Accept.Add(
            new MediaTypeWithQualityHeaderValue("application/json"));
            // List data response.
            HttpResponseMessage response = client.GetAsync(URL).Result;  // Blocking call!
            String res = response.ToString();
            Console.WriteLine(res);

}

即使我传递了正确的凭据，我也会收到未经授权的错误。有什么想法吗？

我尝试了StackOverflow上发布的几乎所有答案。

对于基本身份验证，您需要在名为“Basic”的授权标头中发送凭据，并使用base64编码的“username：password”作为值。这应该完成工作：

var headerVal = Convert.ToBase64String(Encoding.UTF8.GetBytes("admin@client:admin"));
var header = new AuthenticationHeaderValue("Basic", headerVal);
client.DefaultRequestHeaders.Authorization = header;

使用HttpClient时未经授权的错误
