Regex question

[C# Programming]

Hey guys, I've been googling this but with no luck

Here's what I need:

Lets say I've got a piece of plain text in a TextBox or RichTextBox, using a user specified regular expression, I need to find and copy(move to a second text box) everything that matches the said expression.

I hope that makes sense, I've got no real experience with regex so if you could point me to an article that would be great

Thanks
