我要评论本文实例讲述了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。
