title: Random access to specified record within CSV file
body: <p>This code works fine:</p>
  
  <pre><code>            string[] lineOfContents = File.ReadAllLines(@"C:\users.csv");
              foreach (var line in lineOfContents)
              {
                  string[] tokens = line.Split(',');
                  if (tokens[2] == "ed@yahoo.com")
                  {                    
                      MessageBox.Show("Email already exists");
                  }
                 else
                 {
                     MessageBox.Show("Ok");
                 }
              }
  </code></pre>
  
  <p>Above code works like this:

  <p>So, I'd like to have simple code to do "Direct access" to the "Email" record within CSV file, like this:
