In winform, there are two textbox1, textbox2, and textbox2 with a lot of content. Enter the keywords in textbox1, and in textbox2, if there is any, find the relevant content, and return if not.
Thank you very much,
What if several of them match?
And it's better to find one and mark one, so that it has the effect like our Ctrl + F
What should I do?
