You should use the modulus or remainder function and integer division to solve this problem. Using a divisor of 10 you extract one decimal digit at a time from the number. The same technique with a divisor of 16 can be used to extract hexdecimal digits. Int32 num = 123456789; Int32 sum = 0; Int32 temp = num; while (temp > 0) { sum += temp % 10; // sum remainders temp = temp / 10; // integer division } Console.WriteLine("Sum of all digits in {0} is {1}", num, sum); AlanN

Use Regex for this.You can get many example in c#, javascript just search in google. Sarvesh Upadhyay Senior Software Engineer Birlasoft India Ltd. Microsoft Certified Professional Developer in Dotnet 2.0 Enterprise Application

Thnks For Your Help.. I get it Peter

Agree with Dave. If you give the customer exactly and literally what they wanted, you will find that in the end you have a system that is hard to maintain, with a lot of loop holes, and does not handle situations that did not occurs to the customer that it may happens, at that moment.

The split method of the string class will do this for you.

Oh, no, most assuredly not. :-D
