If you only need to find the position of the first appearance, you will be fine with TextBox.Text.IndexOf('x');.

If you need to row too, you will need to make a difference between the lines that are broken because of the size of the textbox and the ones that are there because the user has pressed Enter.

You can do it by using a MemoryStream and a StreamReader.
