Hi, what about a derived class like this one (it's very basic, but it might be what you are searching for):

C# Syntax (Toggle Plain Text)

public class MyStream : StreamReader
		{
			private uint _pos;
 
			public MyStream(string path, System.Text.Encoding enc) : base(path, enc)
			{
			}
 
			public override string ReadLine()
			{
				char current;	
				int i;
				string line = null;
 
				while ((i = base.Read()) != -1)
				{
					current = (char)i;
					_pos++;
 
					if (IsFeed(current))
					{ 
						if ((i = base.Peek()) != -1)
						{
							if (!IsFeed((char)i))
								break;
						}
					}
					else line += current;
				}
 
				return line;
			}
 
			private bool IsFeed(char c)
			{
				if (c == '\r' || c == '\n')
					return true;
 
				return false;
			}
 
			public uint Pos
			{
				get
				{
					return _pos;
				}
			}
		}

public class MyStream : StreamReader { private uint _pos; public MyStream(string path, System.Text.Encoding enc) : base(path, enc) { } public override string ReadLine() { char current; int i; string line = null; while ((i = base.Read()) != -1) { current = (char)i; _pos++; if (IsFeed(current)) { if ((i = base.Peek()) != -1) { if (!IsFeed((char)i)) break; } } else line += current; } return line; } private bool IsFeed(char c) { if (c == '\r' || c == '\n') return true; return false; } public uint Pos { get { return _pos; } } }

Borrowing from Matt's reflection code, here are some extension methods that get the job done:
