WPF XAML Image Source和所需的Windows身份驗證

Question

我想要顯示來自需要Windows身份驗證的網站的圖像。我目前使用這樣的：

<Image Grid.Column="0" Source="https://Foo/899fddb8-d5df-4f04-9d20-50de22f7d671/0102d4d6-3c3d-4717-985b-74021348413d.png" Margin="5,0,0,0" /> 

它適用於瀏覽器，此代碼的工作：

<Image Grid.Column="0" Source="http://img.clubic.com/00C8009607654557-c1-photo-bbpppremium.jpg" Margin="5,0,0,0" /> 

Answer 1

我找到了解決辦法：

在我的App.config中我把：

<system.net> 
    <defaultProxy enabled="true" useDefaultCredentials="true" /> 
    </system.net> 

在我的App類中：

public partial class App : Application 
{ 
    public App() 
    { 
     Current.Startup += CurrentOnStartup; 
    } 

    private void CurrentOnStartup(object sender, StartupEventArgs startupEventArgs) 
    { 
     WebRequest.DefaultWebProxy.Credentials = CredentialCache.DefaultNetworkCredentials; 

     AuthenticationManager.CredentialPolicy = new ProxyCredentials(); 
    } 
} 

internal class ProxyCredentials : ICredentialPolicy 
{ 
    bool ICredentialPolicy.ShouldSendCredential(Uri challengeUri, WebRequest request, NetworkCredential credential, 
     IAuthenticationModule authenticationModule) 

    { 
     return true; 
    } 
}
