IAuthenticationModule.CanPreAuthenticate 屬性

定義

命名空間:

System.Net

組件:

System.Net.Requests.dll

取得值，指出驗證模組是否支援預先驗證。

public:
 property bool CanPreAuthenticate { bool get(); };

public bool CanPreAuthenticate { get; }

member this.CanPreAuthenticate : bool

Public ReadOnly Property CanPreAuthenticate As Boolean

屬性值

Boolean

如果授權模組支援預先驗證，則為 true，否則為 false。

範例

下列範例將示範如何使用 CanPreAuthenticate 屬性。 如需完整的範例，請參閱 類別 AuthenticationManager 。

   String^ m_authenticationType;
   bool m_canPreAuthenticate;

public:

   // The CustomBasic constructor initializes the properties of the customized
   // authentication.
   CustomBasic()
   {
      m_authenticationType = "Basic";
      m_canPreAuthenticate = false;
   }


   property String^ AuthenticationType 
   {

      // Define the authentication type. This type is then used to identify this
      // custom authentication module. The default is set to Basic.
      virtual String^ get()
      {
         return m_authenticationType;
      }

   }

   property bool CanPreAuthenticate 
   {

      // Define the pre-authentication capabilities for the module. The default is set
      // to false.
      virtual bool get()
      {
         return m_canPreAuthenticate;
      }

   }

// Define the authentication type. This type is then used to identify this
// custom authentication module. The default is set to Basic.
public string AuthenticationType { get; } = "Basic";

// Define the pre-authentication capabilities for the module. The default is set
// to false.
public bool CanPreAuthenticate { get; }

Private m_authenticationType As String
Private m_canPreAuthenticate As Boolean


' The CustomBasic constructor initializes the properties of the customized 
' authentication.
Public Sub New()
  m_authenticationType = "Basic"
  m_canPreAuthenticate = False
End Sub

' Define the authentication type. This type is then used to identify this
' custom authentication module. The default is set to Basic.

Public ReadOnly Property AuthenticationType() As String _
 Implements IAuthenticationModule.AuthenticationType

  Get
    Return m_authenticationType
  End Get
End Property

' Define the pre-authentication capabilities for the module. The default is set
' to false.

Public ReadOnly Property CanPreAuthenticate() As Boolean _
 Implements IAuthenticationModule.CanPreAuthenticate


  Get
    Return m_canPreAuthenticate
  End Get
End Property

備註

屬性CanPreAuthenticate設定為 true ，表示呼叫 方法時PreAuthenticate，驗證模組可以使用有效的Authorization實例回應。

給實施者的注意事項

這通常是固定值;驗證模組可以預先驗證，或無法驗證。
