Hey guys!!

I have a date string
                    InitVar.strDOB = AllRx.Rows[odernum]["DOB"].ToString();
 I need to format as follows:
                    19460803

And also a phone number
                    InitVar.strCustPhone = AllRx.Rows[odernum]["PHONE"].ToString();
I need to format as follows:
                    4795555555

Thanks a bunch,
Jerry

For the first:
DateTime.Parse(InitVar.strDOB).ToString("yyyymmdd");
For the second:


for the second:
  string s = "(515) 555 - 2323";
                string t = "";
                foreach( char c in s.ToCharArray())
                    if (char.IsDigit(c))
                        t += c;

Hi JDL129;

The following should do what you need. In the PHONE if there are other formatting characters other then ( ) - add them to the part of the Regex pattern in "[/() -]", after the "[ and before -, the - should be the last one.


using System.Text.RegularExpressions;

InitVar.strDOB = DateTime.Parse(AllRx.Rows[odernum]["DOB"].ToString()).ToString("yyyyMMdd");

InitVar.strCustPhone = Regex.Replace(AllRx.Rows[odernum]["PHONE"].ToString(),
                             "[/() -]", "");

Just noticed that the format string in mine had small m's.  Those are for minutes . . . capital M's is correct for months.

eg:
 ToString("yyyyMMdd");
