本文实例讲述了C#文件流进行压缩和解压缩的方法。分享给大家供大家参考。具体实现方法如下：

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.IO;using System.IO.Compression;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows.Forms;namespace 文件流{ public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { string s = "好好好好好好好好好好好好好好好好好好好好好哈好好好好好啊"; for (int i = 0; i < 10; i++) { s += s; } using (FileStream fs=File.OpenWrite(@"c:\1.txt")) { using (GZipStream zipStream=new GZipStream(fs,CompressionMode.Compress)) { byte[] bytes = Encoding.UTF8.GetBytes(s); zipStream.Write(bytes,0,bytes.Length); MessageBox.Show("压缩成功!"); } } } private void button2_Click(object sender, EventArgs e) { using (FileStream fs=File.OpenRead(@"c:\1.txt")) { using (GZipStream zipStream=new GZipStream(fs,CompressionMode.Decompress)) { using (FileStream fs1=File.OpenWrite(@"c:\upzip.txt")) { int bytesRead; byte[] bytes=new byte[1024]; while((bytesRead=zipStream.Read(bytes,0,bytes.Length))>0) { fs1.Write(bytes,0,bytesRead); } MessageBox.Show("解压成功!"); } } } } }}

希望本文所述对大家的C#程序设计有所帮助。
