Question about Assignment operators

Hi, how to convert this code C# to Visual Cobol?

WhatsApp wap = new WhatsApp(FromNumber, password, nickName, false, false);

wap.OnConnectSuccess += () =>
{
   MessageBox.Show("Connected to whatsapp SuccessFully...");

   wap.OnLoginSuccess += (PhoneNumber, data) =>
   {
     MessageBox.Show("Enterned");
     wap.SendMessage(Phnumber, message);
     MessageBox.Show("Message Sent Successfully...");
    };

  wap.OnLoginFailed += (data) =>
  { 
   MessageBox.Show(data);
   MessageBox.Show("Yes Failed login : {0}", data);
   };

  wap.Login();
};

wap.OnConnectFailed += (ex) =>
{
MessageBox.Show("Conncetion Failure");
};

wap.Connect();
