Web Forms :: Loop Through The Elements Of MyDataReader.Read()

cmd objects returns a set of sampleids. i want to loog through those ids as follows.

myDataReader = cmd.ExecuteReader();
ty{
While(Mydatareader.Read())
{
some logic.....
}
}
catch(exeception ex)
{
Console.Write("{0}", ex.Tostring());
System.Threading.Thread.Sleep(1000 * 60 * 2);
}

everthing is working fine. But when the exception rises the exception shown in command prompt.

What i need is .. when the exception rises .. i need to stop my execution for 2 minutes and then start the loop from the same element .. like using goto statment... but for loop it is working fine .. how to implemnt that logic for mydatareader.read().
