Just like before


[code=c#]
//
//
int Start = 0xE000;
FileStream fs =new FileStream("Som eFile.Com");//you may need to use an overload to support seek
int End = fs.Length;
int lengthtoRead= End - Start;
fs.Seek(Start, SeekOrigin.Begi n);
byte[] buff = new byte[lengthtoRead];
int ActualAmountRea d = fs.Read(buff,0, buff.Length);
//now if ActualAmountRea d is = lengthtoRead, then you have all your bytes in a nice byte[]
//
//
[/code]

I suggest you go read up on the FileStream object in MSDN for information about it.
What i posted was all relatively low math and code usage.
