C# .. API httpclient authentication and proxy with username and password

I'm new in API's world but I had a question, I want to get data from Web API but there's two authentication

here's my Get Action code: 

        HttpClientHandler handler = new HttpClientHandler();
        handler.Credentials = new NetworkCredential("test", "testing");
        HttpClient client = new HttpClient(handler);
        client.BaseAddress = new Uri("http://test.abctesting.com/");
        client.DefaultRequestHeaders.Accept.Clear();
        client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.
            MediaTypeWithQualityHeaderValue("application/json"));

        HttpResponseMessage response = client.GetAsync("admin/apiv2/").Result;
        var tenders = response.Content.ReadAsAsync<tenders>().Result;

this code work fine with me but just in pass over proxy username and password! How can I continue to Get API Data with authentication username and password?

Since you mentioned "Basic Auth" on comments adding the following lines in addition to what you have might help

 var byteArray = Encoding.ASCII.GetBytes($"{yourUsername}:{yourPassword}");
 client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray));

Although there are other popular modes of auth such as OAuth, Bearer etc. Change the key on AuthenticationHeaderValue according to the mode of authentication and set the value appropriately

This should work:

HttpClientHandler handler = new HttpClientHandler();
handler.Credentials = new NetworkCredential("test", "testing");
HttpClient client = new HttpClient(handler);
client.BaseAddress = new Uri("http://test.abctesting.com/");
client.DefaultRequestHeaders.Accept.Clear();

client.DefaultRequestHeaders.Accept.Add(
    new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));

string user = "user", password = "password";

string userAndPasswordToken =
    Convert.ToBase64String(Encoding.UTF8.GetBytes(user + ":" + password));

client.DefaultRequestHeaders.TryAddWithoutValidation("Authorization", 
    $"Basic {userAndPasswordToken}");

HttpResponseMessage response = client.GetAsync("admin/apiv2/").Result;
var tenders = response.Content.ReadAsAsync<tenders>().Result;
