c#压缩解压 文件夹
我在做项目的时候需要将文件进行压缩和解压缩，于是就从pression
foreach (string file in filenames)
{
//打开压缩文件
FileStream fs = File.OpenRead(file);
byte[] buffer = new byte[fs.Length];
fs.Read(buffer, 0, buffer.Length);
ZipEntry entry = new ZipEntry(file);
entry.DateTime = DateTime.Now;
// set Size and the crc, because the information
// about the size and crc should be stored in the header
// if it is not set it is automatically written in the footer.
// (in this case size == crc == -1 in the header)
// Some ZIP programs have problems with zip files that don't store
// the size and crc in the header.
entry.Size = fs.Length;
fs.Close();
crc.Reset();
crc.Update(buffer);
entry.Crc = crc.Value;
s.PutNextEntry(entry);
s.Write(buffer, 0, buffer.Length);
}
s.Finish();
s.Close();
}
}
}
现在再来看看解压文件类的源码
/// <summary>
/// 解压文件
/// </summary>
using System;
using System.Text;
using System.Collections;
using System.IO;
using System.Diagnostics;
using System.Runtime.Serialization.Formatters.Binary;
using System.Data;
using ICSharpCode.SharpZipLib.BZip2;
using ICSharpCode.SharpZipLib.Zip;
using ICSharpCode.SharpZipLib.Zip.Compression;
using ICSharpCode.SharpZipLib.Zip.Compression.Streams;
using ICSharpCode.SharpZipLib.GZip;
namespace DeCompression
{
public class UnZipClass
{
public void UnZip(string[] args)
{
ZipInputStream s = new ZipInputStream(File.OpenRead(args[0]));
ZipEntry theEntry;
while ((theEntry = s.GetNextEntry()) != null)
{
string directoryName = Path.GetDirectoryName(args[1]);
string fileName = Path.GetFileName(theEntry.Name);
//生成解压目录
Directory.CreateDirectory(directoryName);
if (fileName != String.Empty)
{
//解压文件到指定的目录
FileStream streamWriter = File.Create(args[1]+theEntry.Name);
int size = ;
byte[] data = new byte[];
while (true)
{
size = s.Read(data, 0, data.Length);
if (size > 0)
{
streamWriter.Write(data, 0, size);
}
else
{
break;
}
}
streamWriter.Close();
}
}
s.Close();
}
}
}
有了压缩和解压缩的类以后，就要在窗体里调用了。工业源码怎么？是新手，不会调用？Ok,捉妖神器源码在哪接着往下看如何在窗体里调用。
首先在窗体里放置两个命令按钮（不要告诉我你不会放啊~），分片上传源码在哪然后编写以下源码
/// <summary>
/// 调用源码
/// </summary>
private void button2_Click_1(object sender, System.EventArgs e)
{
string []FileProperties=new string[2];
FileProperties[0]="C:\\unzipped\\";//待压缩文件目录
FileProperties[1]="C:\\zip\\a.zip"; //压缩后的目标文件
ZipClass Zc=new ZipClass();
Zc.ZipFileMain(FileProperties);
}
private void button2_Click(object sender, System.EventArgs e)
{
string []FileProperties=new string[2];
FileProperties[0]="C:\\zip\\test.zip";//待解压的文件
FileProperties[1]="C:\\unzipped\\";//解压后放置的目标目录
UnZipClass UnZc=new UnZipClass();
UnZc.UnZip(FileProperties);
}
好了，到此为止，如何压缩和解压缩的类都已经完成了，需要的朋友直接拿走调吧。
