Exemples

L'exemple suivant montre comment définir cette propriété.

// Create a service host.
EndpointAddress ea = new EndpointAddress("http://localhost/Calculator");
WSHttpBinding b = new WSHttpBinding(SecurityMode.Transport);
b.Security.Transport.ClientCredentialType = HttpClientCredentialType.Digest;

// Create a client. The code is not shown here. See the WCF samples
// for an example of the CalculatorClient code.

CalculatorClient cc = new CalculatorClient(b, ea);
// Get a reference to the Windows client credential object.
HttpDigestClientCredential digestCred = cc.ClientCredentials.HttpDigest;
Console.WriteLine("AllowedImpersonationLevel: {0}",
    digestCred.AllowedImpersonationLevel);
Console.WriteLine("Domain: {0}", digestCred.ClientCredential.Domain);

Console.ReadLine();
// Change the AllowedImpersonationLevel.
digestCred.AllowedImpersonationLevel =
    System.Security.Principal.TokenImpersonationLevel.Impersonation;

Console.WriteLine("Changed AllowedImpersonationLevel: {0}",
    digestCred.AllowedImpersonationLevel);
Console.ReadLine();
// Open the calculator and use it.
//cc.Open();
//Console.WriteLine(cc.Add(11, 11));

//// Close the client.
//cc.Close();

Remarques

Les valeurs autorisées incluent :

Delegation,

Identification. Et

Impersonation.

En raison des limitations de l’authentification Digest, seuls les niveaux Impersonation et Delegation sont autorisés lorsque le client utilise des informations d’identification non définies par défaut.
