Surely I don't need to use a DataRow to achieve this?

I can't figure out anything simpler though.

StringBuilder sb = new StringBuilder(); // From System.Text namespace
using (StreamReader re = File.OpenText("abc.txt")) // Using makes sure the reader gets disposed correctly
{
  string input = null;
  while ((input = re.ReadLine()) != null)
  {
    sb.AppendLine(input); // StringBuilder has easy method to add new line and is alot faster than string concat
  }
}
string result = sb.ToString();

string result = null;
using (StreamReader re = File.OpenText("abc.txt")) // Using makes sure the reader gets disposed correctly
{
  result = re.ReadToEnd();
