C# writing to a specific byte in a binary file

Question

how do i write to a overwrite a specific byte in a binary file? i looked around, but i couldn't figure it out.

i figured out how to write to the file, but it write it at the beginning of the file, is there anyway to write it in the middle of the file? or a specified location?

I think you just need to open the file using the FileStream class for writing set the Position property you want to write to call myFileStream.Position = 121; or you can call Seek Then to write to the file public override void Write ( byte [] array  int offset  int count ) if you are only writing one byte then call myFileStream.Write(new byte[]{abyte} 0 1); Don't forget to close the filestream when you are finished.
