The following example reads lines from a file until the end of the file is reached.

C# .NET

public static String DoTest()
{
         string strRet = "";
         string path = @"c:\temp\MyTestReadLine.txt";
         try
         {
                  if (File.Exists(path))
                  {
                           File.Delete(path);
                  }

                  StreamWriter sw = new StreamWriter(path);
                  sw.WriteLine("This");
                  sw.WriteLine("is some text");
                  sw.WriteLine("to test");
                  sw.WriteLine("ReadLine method");
                  sw.Flush();
                  sw.Close();

                  StreamReader sr = new StreamReader(path);
                  while (sr.Peek() >= 0)
                  {
                           strRet += (sr.ReadLine() + Environment.NewLine);
                  }
                  sr.Close();
         }
         catch (Exception e)
         {
                  strRet += String.Format("The process failed: {0}", e.ToString());
         }

         return strRet;
}
