ignore case sensitive in regex.replace?

Question

I have this code to search in a string and replace some text with other text:

Regex regexText = new Regex(textToReplace);
retval = regexText.Replace(retval, Newtext);

textToReplace may be "welcome" or "client" or anything.

I want to ignore case for textToReplace so that "welcome" and "Welcome" both match.

How can I do this?

Answer 1

You may try:

Regex regexText = new Regex(textToReplace, RegexOptions.IgnoreCase);
