Hello Friends,

I am working on a web application in which I am getting a string from database and breaking it to use it. This is the string: string str = "DB1031229";

But sometimes I am not getting proper results. I need to break it in :

DB

10

1229

You can notice that I have not included 3 in that. I dont need that. Please suggest a solution using Regular expressions or some error free way.

Thanks in advance.

Thanks,
Jagjot

Solution 3

If the length of the string is always same you can use string operations l

string numbers = "DB1031229";
        string s0 = numbers.Substring(0, 2);
        string s9 = numbers.Substring(2, 2);
        string s10 = numbers.Substring(5);

Solution 2

using System.Text.RegularExpressions;
Regex r = new Regex("DB");
           var v = "DB1031229";
           string[] s = r.Split(v);
           Match n = r.Match(v);
             string v1=n.ToString();//DB
          string v2 = s[1].Substring(0, 2);//"10"
         string  v3 = s[1].Substring(3); //"1229"
