Regex pattern to choose data BETWEEN matching quotation marks

Question

Suppose I had the following string I wanted to run a Regular expression on:

This is a test string with \"quotation-marks\" within it.
The \"problem\" I am ha         


        

Answer 1

Instead of a regex, a regular method to do this might be more maintainable in the long run:

public static String replaceDashInQuotes(this string source, String newValue)
{
    StringBuilder sb = new StringBuilder();

    bool inquote = false;

    for (int i = 0; i < source.Length; i++)
    {
        if (source[i] == '\"')
            inquote = !inquote;

        if (source[i] == '-' && inquote)
            sb.Append(newValue);
        else
            sb.Append(source[i]);
    }

    return sb.ToString();
}

Then to use it:

var s = @"This is a test string with ""quotation-marks"" within it.
    The ""problem"" I am having, per-se, is ""knowing"" which ""quotation-marks""
    go with which words.";

MessageBox.Show(s.replaceDashInQuotes(" "));
