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