DnsPermission.ToXml 메서드

정의

네임스페이스:

System.Net

어셈블리:

System.Security.Permissions.dll

DnsPermission 인스턴스 및 현재 상태의 XML 인코딩을 만듭니다.

public:
 override System::Security::SecurityElement ^ ToXml();

public override System.Security.SecurityElement ToXml ();

override this.ToXml : unit -> System.Security.SecurityElement

Public Overrides Function ToXml () As SecurityElement

반환

SecurityElement

상태 정보를 포함하여 보안 개체의 XML 인코딩 표현이 들어 있는 SecurityElement 인스턴스입니다.

예제

다음 예제에서는 인스턴스의 XML 인코딩을 DnsPermission 만듭니다.

public:
   void useDns()
   {
      // Create a DnsPermission instance.
      DnsPermission^ permission = gcnew DnsPermission( PermissionState::Unrestricted );
      
      // Check for permission.
      permission->Demand();
      // Create a SecurityElement Object* to hold XML encoding of the DnsPermission instance.
      SecurityElement^ securityElementObj = permission->ToXml();
      Console::WriteLine( "Tag, Attributes and Values of 'DnsPermission' instance :" );
      Console::WriteLine( "\n\tTag : {0}", securityElementObj->Tag );
      // Print the attributes and values.
      PrintKeysAndValues( securityElementObj->Attributes );
   }

private:
   void PrintKeysAndValues( Hashtable^ myList )
   {
      // Get the enumerator that can iterate through the hash table.
      IDictionaryEnumerator^ myEnumerator = myList->GetEnumerator();
      Console::WriteLine( "\n\t-KEY-\t-VALUE-" );
      while ( myEnumerator->MoveNext() )
      {
         Console::WriteLine( "\t {0}:\t {1}", myEnumerator->Key, myEnumerator->Value );
      }
      Console::WriteLine();
   }

public void useDns() {

   // Create a DnsPermission instance.
   DnsPermission permission = new DnsPermission(PermissionState.Unrestricted);

   // Check for permission.
   permission.Demand();
   // Create a SecurityElement object to hold XML encoding of the DnsPermission instance.
   SecurityElement securityElementObj = permission.ToXml();
   Console.WriteLine("Tag, Attributes and Values of 'DnsPermission' instance :");
   Console.WriteLine("\n\tTag :" + securityElementObj.Tag);
   // Print the attributes and values.
   PrintKeysAndValues(securityElementObj.Attributes);
}

private void PrintKeysAndValues(Hashtable myList) {
   // Get the enumerator that can iterate through the hash table.
   IDictionaryEnumerator myEnumerator = myList.GetEnumerator();
   Console.WriteLine("\n\t-KEY-\t-VALUE-");
   while (myEnumerator.MoveNext())
      Console.WriteLine("\t{0}:\t{1}", myEnumerator.Key, myEnumerator.Value);
   Console.WriteLine();
}

Public Sub useDns()
    ' Create a DnsPermission instance.
    Dim permission As New DnsPermission(PermissionState.Unrestricted)
    
    ' Check for permission.
    permission.Demand()
    ' Create a SecurityElement object to hold XML encoding of the DnsPermission instance.
    Dim securityElementObj As SecurityElement = permission.ToXml()
    Console.WriteLine("Tag, Attributes and Values of 'DnsPermission' instance :")
    Console.WriteLine((ControlChars.Cr + ControlChars.Tab + "Tag :" + securityElementObj.Tag))
    ' Print the attributes and values.
    PrintKeysAndValues(securityElementObj.Attributes)
End Sub

Private Sub PrintKeysAndValues(myList As Hashtable)
    ' Get the enumerator that can iterate through the hash table.
    Dim myEnumerator As IDictionaryEnumerator = myList.GetEnumerator()
    Console.WriteLine(ControlChars.Cr + ControlChars.Tab + "-KEY-" + ControlChars.Tab + "-VALUE-")
    While myEnumerator.MoveNext()
        Console.WriteLine(ControlChars.Tab + "{0}:" + ControlChars.Tab + "{1}", myEnumerator.Key, myEnumerator.Value)
    End While
    Console.WriteLine()
End Sub

설명

메서드는 ToXml 인스턴스를 SecurityElement 만들어 상태 정보를 포함하여 인스턴스의 표현을 DnsPermission XML로 인코딩합니다.

메서드를 FromXml 사용하여 인스턴스에서 상태 정보를 복원합니다 SecurityElement .
