TextReader and TextWriter are your friends here.
Look up their specs for them, try the code and post back if you get errors with it.

StreamReader sr = new StreamReader(File.OpenRead(@"F:\src.txt"));
string fileContent = sr.ReadToEnd();
sr.Close();

StreamWriter writer = new StreamWriter(File.Create(@"F:\dest.txt"));
writer.Write(fileContent);
writer.Close();

this is my code that simply reads from src.txt n writes that 2 dest.txt,now my prob is that i donno how to read values in chunks of 4 ,take thei mean and then write the result in another file,itz actually the syntax i get stuck on

StreamReader has a ReadLine method. Use that instead of the ReadToEnd method.
As I said, open the specs for those classes and check the methods for yourself.
Also have a look at the StringWriter and StringReader classes
