Read all lines of a text file

while((readLine = tr.ReadLine()) != null)

                {

                    readLine = readLine.Trim();

                    if (readLine == "") continue; // ignore blank lines

                    string[] items = readLine.Split(';');

                    accountName = items[0];

                    contactFName = items[1];

                    contactLName = items[2];

                    Console.WriteLine("attr1 = {0}, attr2 = {1}, attr3 = {2}, attr4 = {3}" + accountName + contactFName + contactLName);

                    counter++;

                }

The issue is you reading the line twice and it will take the second line. It reads one line in the while entry and you need to process it, but again you are the next row inside.
