title: How can I add a huge string to a textbox efficiently?
body: <p>I have a massive string (we are talking 1696108 characters in length) which I have read very quickly from a text file. When I add it to my textbox (C#), it takes ages to do. A program like Notepad++ (unmanaged code, I know) can do it almost instantly although Notepad takes a long time also. How can I efficiently add this huge string and how does something like Notepad++ do it so quickly?</p>
