次の例では、 を使用 WebPermissionAttribute して許容される ConnectPatternを指定する方法を示します。

public:
   // Set the WebPermissionAttribute ConnectPattern property.
   [WebPermission(SecurityAction::Deny,ConnectPattern="http://www\\.contoso\\.com/Private/.*")]

   static void CheckConnectPermission( String^ uriToCheck )
   {
      WebPermission^ permissionToCheck = gcnew WebPermission;
      permissionToCheck->AddPermission( NetworkAccess::Connect, uriToCheck );
      permissionToCheck->Demand();
   }

   static void demoDenySite()
   {
      //Pass the security check.
      CheckConnectPermission( "http://www.contoso.com/Public/page.htm" );
      Console::WriteLine( "Public page has passed Connect permission check" );

      try
      {
         //Throw a SecurityException.
         CheckConnectPermission( "http://www.contoso.com/Private/page.htm" );
         Console::WriteLine( "This line will not be printed" );
      }
      catch ( SecurityException^ e ) 
      {
         Console::WriteLine( "Expected exception {0}", e->Message );
      }
   }
};

  
  // Set the WebPermissionAttribute  ConnectPattern property.
  [WebPermission(SecurityAction.Deny, ConnectPattern=@"http://www\.contoso\.com/Private/.*")]

public static void CheckConnectPermission(string uriToCheck) 
{
    WebPermission permissionToCheck = new WebPermission();
    permissionToCheck.AddPermission(NetworkAccess.Connect, uriToCheck);
    permissionToCheck.Demand();
}

public static void demoDenySite() {
    //Pass the security check.
    CheckConnectPermission("http://www.contoso.com/Public/page.htm");
    Console.WriteLine("Public page has passed Connect permission check");

    try 
    {
        //Throw a SecurityException.
        CheckConnectPermission("http://www.contoso.com/Private/page.htm");
        Console.WriteLine("This line will not be printed");
    }
    catch (SecurityException e) 
    {
        Console.WriteLine("Expected exception" + e.Message);
    }
 }

  ' Set the WebPermissionAttribute  ConnectPattern property.
<WebPermission(SecurityAction.Deny, ConnectPattern := "http://www\.contoso\.com/Private/.*")> _
    Public Shared Sub CheckConnectPermission(uriToCheck As String)
     Dim re As New Regex("http://www\.contoso\.com/Public/.*")
     Dim con As New WebPermission(NetworkAccess.Connect, re)
     con.Assert()
     Dim permissionToCheck As New WebPermission()
     permissionToCheck.AddPermission(NetworkAccess.Connect, uriToCheck)
     permissionToCheck.Demand()
  End Sub
  
  
  Public Shared Sub demoDenySite()
     'Pass the security check.
     CheckConnectPermission("http://www.contoso.com/Public/page.htm")
     Console.WriteLine("Public page has passed Connect permission check")
     
     Try
