Open original thread
const string numericReg = "\\d+"; // Matches a digit character. Equivalent to [0-9].
const string realNumsReg = numericReg + b + "(\\." + b + numericReg + ")?";
        const string b = "\\s*";
 
 

This statement is true :
 
  private const string rte = "(?<rate>" + realNumsReg + ")" +
                            "(?=(?<rte1>" + b + "qs " + "))";
 
and
 
This statement is true :
 
 private const string barl = "(?<barl>" + numericReg + ")" +
                                    "(?=((?<q>" + b + "point to print )))";
 

this is true for rte :
 
MatchCollection s = Regex.Matches
                ("3000 qs / min", rte , RegexOptions.IgnoreCase);
 
this is true for barl:
 
MatchCollection s = Regex.Matches
                ("6 point to print  ", barl , RegexOptions.IgnoreCase);
 
Why is this wrong?
 
 MatchCollection s = Regex.Matches
                ("6 point to print  3000 qs/ min", barl+b+rte  , RegexOptions.IgnoreCase);
