This is the C# code I believe:

    public static string StrExtract(string cSearchExpression, string cBeginDelim, string cEndDelim, int nBeginOccurence, int nFlags) {
        string cstring = cSearchExpression;
        string cb = cBeginDelim;
        string ce = cEndDelim;
        string lcRetVal = "";
        if ((nFlags == 1)) {
            cstring = cstring.ToLower();
            cb = cb.ToLower();
            ce = ce.ToLower();
        }
        // Lookup the position in the string
        int nbpos = VFPToolkit.strings.At(cb, cstring, nBeginOccurence);
        if ((cSearchExpression.Substring(nbpos, ce.length) != ce)) {
            int nepos = cstring.IndexOf(ce, (nbpos + 1));
            // Extract the part of the strign if we get it right
            if ((nepos > nbpos)) {
                lcRetVal = cSearchExpression.Substring(nbpos, (nepos - nbpos));
            }
            else if ((nepos < 1)) {
                lcRetVal = cSearchExpression.Substring(nbpos);
            }
        }
        return lcRetVal;
    }
