Valore della proprietà

TokenImpersonationLevel

Enumerazione TokenImpersonationLevel concessa dal client al server come parte dell'autenticazione del digest HTTP.

Esempio

Nell'esempio seguente viene illustrato come impostare questa proprietà.

// 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();

' Create a service host.
Dim ea As New EndpointAddress("http://localhost/Calculator")
Dim b As 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.
Dim cc As New CalculatorClient(b, ea)
' Get a reference to the Windows client credential object.
Dim digestCred As HttpDigestClientCredential = 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()

Commenti

I valori consentiti includono:

Delegation,

Identification e

Impersonation.

A causa delle limitazioni dell'autenticazione digest, quando il client utilizza credenziali non predefinite, sono consentiti solo i livelli Impersonation e Delegation.
