but it makes function calls, it's not neglectable as it's called as many time as the bytes the file has

That’s the api provided, and part of the point. The other option is to read the buffer directly, but it isn’t exposed to the programmer.

  int StreamReader.Read(char[] buffer, int index, int count)

You just need to do File.OpenRead instead of OpenText to get a FileStream, then you can read the buffer
