Find mobile number from string c#

RegEx in C#[^]

Seems like a list of comma delimited values to me. If the mobile number have a fixed place in the list, you can split the string into separate fields and access the required field by its index:

string foo = ",38,,,,,,,,,,,,,,,,,,,,,,,,,,,,382350,,,,,0,,,,8141884584,,,,,,,,";
string[] bar = foo.Split(',');
MessageBox.Show(bar[38]);

string strData=",38,,,,,,,,,,,,,,,,,,,,,,,,,,,,382350,,,,,0,,,,8141884584,,,,,,,,";

char[] separator = new char[] { ','
string[] strSplitArr = strData.Split(separator);

for (int q = 0; q < strSplitArr.Length; q++)
        {
            if (strSplitArr[q] != "")
            {
                int no = 0;

                no = strSplitArr[q].Length;
                if (no >= 10 && no <= 12)
                {
                    numString += strSplitArr[q].ToString() + ", ";
                }
            }
        }
