示例1: Main
//引入命名空间
using System;
using System.IO;
using System.Text;
public class BinReadWrite
{
public static void Main()
{
string testfile = @"C:\temp\testfile.bin";
// create a test file using BinaryWriter
FileStream fs = File.Create(testfile);
UTF8Encoding utf8 = new UTF8Encoding();
BinaryWriter bw = new BinaryWriter(fs, utf8);
// write a series of bytes to the file, each time incrementing
// the value from 0 - 127
int pos;
for (pos = 0; pos < 128; pos++)
{
bw.Write((byte)pos);
}
// reset the stream position for the next write pass
bw.Seek(0, SeekOrigin.Begin);
// write marks in file with the value of 255 going forward
for (pos = 0; pos < 120; pos += 8)
{
bw.Seek(7, SeekOrigin.Current);
bw.Write((byte)255);
}
// reset the stream position for the next write pass
bw.Seek(0, SeekOrigin.End);
// write marks in file with the value of 254 going backward
for (pos = 128; pos > 6; pos -= 6)
{
bw.Seek(-6, SeekOrigin.Current);
bw.Write((byte)254);
bw.Seek(-1, SeekOrigin.Current);
}
// now dump the contents of the file using the original file stream
fs.Seek(0, SeekOrigin.Begin);
byte[] rawbytes = new byte[fs.Length];
fs.Read(rawbytes, 0, (int)fs.Length);
int i = 0;
foreach (byte b in rawbytes)
