如何创建 InlineKeyboardMarkup 这个例子？

Question

我想创建一个按钮，当点击按钮时用户会转到群电报。但不能

使用 NetTelegramBotApi； // 最后一个版本

class Program
    {
        private static string Token = "......";
       // private static InlineKeyboardMarkup Menu1;
    }


  public static async Task RunBot()
        {


 // var keyboardInlineMenu = new InlineKeyboardButton[20][];

.....
.....
....
....

if (text == "/start")
  {


// keyboardInlineMenu  = new InlineKeyboardButton () {


InlineKeyboardButton[][] buttons = new InlineKeyboardButton[2][];
buttons[0][0] = new InlineKeyboardButton(){Text = " Go to group  ", Url = "https://api.telegram.org/......" CallbackData = "Some Callback Data"};
InlineKeyboardMarkup inlineKeyboardMarkup = new InlineKeyboardMarkup() { InlineKeyboard = buttons  };

错误（行按钮[0][0]）

Object reference not set to an instance of an object.

                                    {
                                        InlineKeyboard = new[] 
        {
            new[] { new InlineKeyboardButton{Text="A",Url = "http://www.A.com/"}, new InlineKeyboardButton(){Text="B",Url = "http://www.B.com/"} }

        }
                                    }
                            };

                            await bot.MakeRequestAsync(newMsg);
                            continue;
