>FileStream Headerfp = new FileStream
(path,FileMode.Open,System.IO.FileAccess.Read);

The third parameter in this particular overload of the FileStream
constructor is how your program is allowed to access the underlying
file.

What you need is the following:

FileStream Headerfp = new FileStream(path, FileMode.Open,
System.IO.FileAccess.Read, System.IO.FileShare.ReadWrite);

This is an overload of the FileStream constructor which also accepts a
parameter called FileShare which determines how the file will be
shared by other processes.
