C# Reading file into bytes, then converting it to string, then converting it back to bytes

Hi, I seem to have a problem when reading file into bytes, then converting it to string, then converting it back to bytes.

The code is:

byte[] buff = null;
FileStream fs = new FileStream(System.IO.Path.GetTempPath() + "/myprogram.exe", FileMode.Open, FileAccess.Read);
BinaryReader br = new BinaryReader(fs);
long numBytes = new FileInfo(System.IO.Path.GetTempPath() + "/myprogram.exe").Length;
buff = br.ReadBytes((int)numBytes);

 System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding();

string buffasstring = encoding.GetString(buff);
byte[] prgbk2bytes= encoding.GetBytes(buffasstring);


--
Why are prgbk2bytes bytes are diffrent to the orignal program bytes? How can I get the original program bytes back after converting it to string.

Many thanks
