How to verify the third character of a textBox.Text

Question

In short, something like this:

private void checkMethod()
{
    if (textBoxCode.Text.Contains("a").Position(Char.3)))
    {
        // Then do this...
    }
}

If I understand your pseudo code completely. There are many ways, however I guess you could do something like

if(textBoxCode.Text?.Length >= 3 && textBoxCode.Text[2] == 'a')

_{Calling textBoxCode.Text?.Length is basic fault tolerance}

Or you could use ElementAtOrDefault, which does all the above

Returns the element at a specified index in a sequence or a default value if the index is out of range.

if(textBoxCode.Text?.ElementAtOrDefault(2) == 'a')
