Question

How can I use the String.Replace function to use Patterns?

What I would like to do:

newTextBox = newTextBox.Replace("<Value> #'a string of any number of chars#' </Value>", 
                                "<Value>" + textBoxName + "</Value>");

#’a string of any number of chars#’ can be any string.

Use a regular expression:

newTextBox.Text =
    Regex.Replace(
        newTextBox.Text,
        @"<Value>[^\<]+</Value>",
        "<Value>" + textBoxName.Text + "</Value>");
