WebPermissionAttribute::ConnectPattern Property

Gets or sets a regular expression pattern that describes the URI connection controlled by the current WebPermissionAttribute.

Namespace:  System.Net
Assembly:  System (in System.dll)

public:
property String^ ConnectPattern {
	String^ get ();
	void set (String^ value);
}

Property Value

Type: System::String
A string containing a regular expression pattern that describes the URI connection controlled by this WebPermissionAttribute.

ExceptionCondition
ArgumentException

ConnectPattern is not nullptr when you attempt to set the value. If you wish to specify more than one connect URI, use an additional attribute declaration statement.

When applying WebPermissionAttribute to your class, this property specifies what regular expression connect string is accepted for use within your class. This property is write-once.

The following example demonstrates how to use WebPermissionAttribute to specify an allowable ConnectPattern.

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 );
      }
   }
};
