Return StreamReader to Beginning

Question

I\'m reading a file in line-by-line and I want to be able to restart the read by calling a method Rewind().

How can I manipulate my System.IO.Stre

Answer 1

public long ReadList(string fileName, Action action,long position=0)
{
  if (!File.Exists(fileName)) return 0;

  using (var reader = new StreamReader(File.Open(fileName, FileMode.Open, FileAccess.Read, FileShare.ReadWrite),System.Text.Encoding.Unicode))
  {
    if (position > 0)reader.BaseStream.Position = position;

     while (!reader.EndOfStream)
     {
       action(reader.ReadLine());
     }
     return reader.BaseStream.Position;
   }
}
