I have a string value of

string test = "99999\tAAAAAA\tOH\tX1 \tCentral\t754"
"99999\BBBB\tOH\tX1 \tCentral\t1234"
"99999\tfasdfjhsjf\tWV\tX1 \tCentral\t12345"

for int code , I want the value after the last "\t" from the above string values. How do I do that?

int i = test.LastIndexOf("\t");
string value = test.Substring(i+1);

Have you tried this:
int index = test.LastIndexOf("\t");
int code = 0;
if (index > -1)
   code = int.Parse(test.Substring(index + 1));

Hi pratikshahse;

This will do it.

    // Test Data
    string test = @"99999\tAAAAAA\tOH\tX1 \tCentral\t75499999\BBBB\tOH\tX1 \tCentral\t123499999\tfasdfjhsjf\tWV\tX1 \tCentral\t12345";

    // The needed data
    string data = test.Substring(test.LastIndexOf("\\") + 1);

This will pick out the digits between the last \t and the end of the string, and convert it to an integer:

Match match = Regex.Match(test, @"\t(\d+)$");
string digits = match.Groups[0].Captures[0].Value;
int value = int.Parse(digits);
