Error 401 in C#

Question

I'm working on my first app for Windows 8 but I have a problem, when I'm launch my app, I've got the error "Response status code does not indicate success:

401 (Authorization Required)

So yes, I need to include username and password but I don't know where in my code:

var fond = new HttpClient();
var reponse = await fond.GetStreamAsync("http://example.com/search/mario%20kart" + TitleNewsGrid.Text);

So where I'm include the username and password in the code?

Check here en.wikipedia.org/wiki/List_of_HTTP_status_codes It seems an issue related to the authorization of the web server! — iSamnium

@iSamnium The OP understands what the error is, they are asking how to pass credentials to the server not what the status code represents. — James

There should be a Credentials property in the TransportSettings e.g.

using (var client = new HttpClient())
{
    client.TransportSettings.Credentials = new System.Net.NetworkCredential("username", "pwd");
    ...
}

If you don't have access to the TransportSettings property, you will need to use HttpClientHandler instead. No point in duplicating code, there is already a good example here.

Notice the use of the using statement, which causes the client to get automatically disposed when it leaves the scope.

Hey :) Thanks for your help. For the moment i use: System.Net.Http.HttpClient Fond = new HttpClient(); But TransportSettings don't use System.Net.Http.HttpClient... So I'm a little missed ^^'

@GuillaumeFortunier did you find the TransportSettings property?

Guillaume Fortunier Over a year ago

private async void PremierTest() { using (var handler = new HttpClientHandler()) { handler.Credentials = new System.Net.NetworkCredential("appendr", "e32!cdf"); using (var client = new HttpClient(handler){}) { System.Net.Http.HttpClient Fond = new HttpClient(); var reponse = await Fond.GetStreamAsync("ws.jeuxvideo.com/search/mario%20kart" + TitleNewsGrid.Text); but block at Fond.GetStreamAsync

Sounds like you may be hitting a deadlock in your code. Try the solution provided here and I would recommend reading the answer posted here as well.
