How to use the Microsoft Bot Framework to make buttons in several rows?

It is necessary to create several rows of keyboard buttons with different numbers in the row for the Telegram. How to make one row is understandable, but I don’t understand how to make several rows of this with a controlled number of buttons in a row.

  msg.SuggestedActions = new SuggestedActions() { Actions = new List<CardAction>() { new CardAction(){ Title = "Пользователь", Type=ActionTypes.ImBack, Value="Пользователь" }, new CardAction(){ Title = "Сервера", Type=ActionTypes.ImBack, Value="Сервера" }, new CardAction(){ Title = "Сеть", Type=ActionTypes.ImBack, Value="Сеть" }, new CardAction(){ Title = "Консультант", Type=ActionTypes.ImBack, Value="Консультант" } } };
