Help with Regex?

Question

I want to replace

! = change

@ = static(does not)

$ = Want to replace

I got a sting like this @!$! How do I replace the $ with something else?

EDIT: I need to use Regex as the string may appear anywhere!

Answer 1

You don't need a regular expression, just use the String.Replace method:

String result = input.Replace("$", "somethingElse");

---

As a side note: The way that you would do this with a regular expression would be like this:

String result = Regex.Replace(input, @"\$", "somethingElse");

Notice that I have escaped the $ with a backslash since $ usually means match the end of the string.

Answer 2

Using the String class' .Replace() method would do the trick but, if you really want to use RegEx, this is a great RegEx site that I use quite often.

Regular Expression Library

You should be able to find what you're looking for there.

Answer 3

Why do you want some RegExp for string replacement. You can just use string.Replace() fundtion.

Answer 4

Take a look at System.Text.RegularExpressions.Regex.Replace method.

Regex.Replace("@!$!", "!(.*)!", "replacement value");
