basically I want it to do this :

try smething like this:

Textbox1.Text.StartsWith("a") ? do something : do something else;

and if it is not just about first character then try something like:

Textbox1.Text.Contains("a") ? do something : do something else;

  if (Textbox1.Text.StartsWith("a")) {
    // do stuff
    ...
  }

.length only returns an integer of length of the string. This will compare the first char with 'a'.

if(Textbox1.text[0] == 'a')
