The following code example demonstrates accessing the ServicePoint property.

   static void CreateTestMessage1( String^ server, int port )
   {
      String^ to = L"jane@contoso.com";
      String^ from = L"ben@contoso.com";
      String^ subject = L"Using the new SMTP client.";
      String^ body = L"Using this new feature, you can send an e-mail message from an application very easily.";
      MailMessage^ message = gcnew MailMessage( from,to,subject,body );
      SmtpClient^ client = gcnew SmtpClient( server,port );

      // Credentials are necessary if the server requires the client  
      // to authenticate before it will send e-mail on the client's behalf.
      client->Credentials = CredentialCache::DefaultNetworkCredentials;

      //Display the properties on the service point.
      ServicePoint^ p = client->ServicePoint;
      Console::WriteLine( L"Connection lease timeout: {0}", p->ConnectionLeaseTimeout );
      client->Send( message );
	  client->~SmtpClient();
   }
public:
   static void CreateTestMessage1(String* server ,int port )
    {
        String* to = S"jane@contoso.com";
        String* from = S"ben@contoso.com";
        String* subject = S"Using the new SMTP client.";
        String* body  = S"Using this new feature, you can send an e-mail message from an application very easily.";
        MailMessage* message = new MailMessage(from, to, subject, body);
        SmtpClient* client = new SmtpClient(server, port);
        // Credentials are necessary if the server requires the client 
        // to authenticate before it will send e-mail on the client's behalf.
        client->Credentials = CredentialCache::DefaultNetworkCredentials;
        //Display the properties on the service point.
        ServicePoint* p = client->ServicePoint;
        Console::WriteLine(S"Connection lease timeout: {0}", __box(p->ConnectionLeaseTimeout));
        client->Send(message);
        client->Dispose();
    }
