HttpDigestClientCredential.AllowedImpersonationLevel 屬性

定義

命名空間:

System.ServiceModel.Security

組件:

System.ServiceModel.dll

取得或設定用戶端允許以提供之用戶端認證進行模擬的層級。

public:
 property System::Security::Principal::TokenImpersonationLevel AllowedImpersonationLevel { System::Security::Principal::TokenImpersonationLevel get(); void set(System::Security::Principal::TokenImpersonationLevel value); };

public System.Security.Principal.TokenImpersonationLevel AllowedImpersonationLevel { get; set; }

member this.AllowedImpersonationLevel : System.Security.Principal.TokenImpersonationLevel with get, set

Public Property AllowedImpersonationLevel As TokenImpersonationLevel

屬性值

TokenImpersonationLevel

TokenImpersonationLevel，這是用戶端在 HTTP 摘要式驗證中授與伺服器的一部分。

範例

下列範例將示範如何設定這個屬性。

// 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()

備註

允許的值包括：

Delegation,

Identification，以及

Impersonation.

由於摘要式驗證的限制，當用戶端使用非預設的認證時，只允許其使用 Impersonation 和 Delegation 層級。
