How to place a button in a column?

Thanks You!

P.S. Source code:

stringArray)
{
var keyboardInline = new InlineKeyboardButton[1][];
var keyboardButtons = new InlineKeyboardButton[stringArray.Length];
for (var i = 0; i < stringArray.Length; i++)
{
    keyboardButtons[i] = new InlineKeyboardButton
    {
        Text = stringArray[i],
        CallbackData = "Some Callback Data",
    };
}
keyboardInline[0] = keyboardButtons;
return keyboardInline;
}

    You need to put each button in array.
    Reply markup: keyboard & inline keyboard

    Notes:

    1. Change return type for GetInlineKeyboard to InlineKeyboardMarkup instead of InlineKeyboardButton[][]
    2. Use explicit types instead of implicit (var)
    3. Use List<InlineKeyboardButton> instead of Array (InlineKeyboardButton[])
    4. Don’t create buttons with same callback data
    5. Replace method parameters to take IDictionary<string, string> to get text and callback data

    Every IEnumerable<InlineKeyboardButton> Is single row, This means you should pass list of rows.

    You shouldn’t use var keyboardInline = new InlineKeyboardButton[1][]; because this means only one row with buttons in this row!

    There are two ways below:

    Code you wants:

    I don’t suggest this code

    private static InlineKeyboardButton[][] GetInlineKeyboard(string[] stringArray)
{
    var keyboardInline = new InlineKeyboardButton[stringArray.Length][];

    for (var i = 0; i < stringArray.Length; i++)
    {
        keyboardInline[i] = new InlineKeyboardButton[]
        {
            new InlineKeyboardButton
            {
                Text = stringArray[i],
                CallbackData = "Some Callback Data",
            };
        }
    }

    return keyboardInline;
}

    Best way:

    I suggest this code:

    private static InlineKeyboardMarkup GetInlineKeyboard(IDictionary<string, string> buttonsData)
{
    // Rows Count
    int count = buttonsData.Length;

    // List of rows 
    // Every 'List<InlineKeyboardButton>' is row
    List<List<InlineKeyboardButton>> buttons = new List<List<InlineKeyboardButton>>(count);    

    for (int i = 0; i < count; i++)
    {
        // Add new row with one button capacity
        buttons.Add(new List<InlineKeyboardButton>(1)
        {
            // Add button to this row
            new InlineKeyboardButton
            {
                Text = buttonsData.Values.ElementAt(i),
                CallbackData = buttonsData.Keys.ElementAt(i),
            }
        });
    }
    
    return new InlineKeyboardMarkup(buttons);
}

    I’m not sure if the code has massively changed as I haven’t tried the above method(answered by Muaath), but this was the fix for me, inspiration from Muaath answer above:

    public async Task<InlineKeyboardMarkup> GetInlineKeyboardMarkup(IReadOnlyList<SomeClassObject> someClassObject)
        {

            int count = someClassObject.Count;
            List<List<InlineKeyboardButton>> buttons = new List<List<InlineKeyboardButton>>(someClassObject.Count);

            for (int i = 0; i < count; i++)
            {
                // Add new row with one button capacity
                buttons.Add(new List<InlineKeyboardButton>(1)
                {
                      InlineKeyboardButton.WithCallbackData(text: $"{someClassObject[i].Title}", callbackData: $"{someClassObject[i].Id}"),
                });
            }

            return new InlineKeyboardMarkup(buttons);
        }

    Note the difference is there is now a new method: InlineKeyboardButton.WithCallbackData()
