Split and save data in list using C#

try this

List<string> strlist = new List<string>();
           strlist.Add("Invoice # 120 ");
           strlist.Add("Invoice # 130 ");
           strlist.Add("Invoice # 140 ");
           List<int> intlist=new List<int>();

           foreach (String str in strlist)
           {
               intlist.Add(Convert.ToInt32(Regex.Match(str, @"\d+").Value));
           }

Try below code according to your requirement:

 string[] ArrInvoice = { "Invoice # 120", "Invoice # 121", "Invoice # 122", "Invoice # 123" };
            List<int> lstInvice = new List<int>();
            foreach (string item in ArrInvoice)
            {
                int intInvocie = 0;               
                Int32.TryParse(item.Split('#')[1], out intInvocie);
                if (intInvocie>0)
                {
                    lstInvice.Add(intInvocie);
                }
            }
</int></int>

Hope this will fulfill your requirement.

Hi ,

you can do this in many ways -

Solution1:
you can fetch only integer from any string using regular expression.
1.add this namespace

using System.Text.RegularExpressions;

2. Fetch only numeric value

string[] status = Regex.Split(gridview.cell[0].tostring(), @"\D+");

3.put this in you list

List<int> list = new List<int>();
    list.Add(status[0]);
    list.Add(status[0]);
    list.Add(status[0]);

Solution2:
split your string where getting # ->

string abc = "aaa#12";  //put here your gridview text
           string[] cdf = abc.Split('#');

i have just given you idea using above you can solve your proble .:) happy coding dear :)
