Regex Pattern number1 to number2

Question

I\'m searching for a pattern for the following behavior:

number1-number2
number1: Can be everything >= 0 and <= int.MaxValue
number2: Can be everything >         


        

Answer 1

Regex can only be used to match the numbers. Post that a comparison operation needs to be done.

string num="number1-number2";//where (number1 & number2)=numeric val
MatchCollection stringVal= Regex.Matches(num,@"\d+");
int num1=Convert.ToInt32(stringVal[0].Value);
int num2=Convert.ToInt32(stringVal[1].Value);
if(num1>=0 && num1<=int.MaxValue && num2>=num1 && num2<=int.MaxValue)
    return true;
else
   return false;

will give you an array containing the the numbers
