namespace Ehai.FileUnzip

public class Unzip

{

public void UnzipFiles(string SourceZip, string DesPath,bool cover)

{

ZipInputStream stream = new ZipInputStream(File.OpenRead(SourceZip));

ZipEntry theEntry;

if (!Directory.Exists(DesPath)) Directory.CreateDirectory(DesPath);

if (DesPath[DesPath.Length - 1] != Path.DirectorySeparatorChar

DesPath += Path.DirectorySeparatorChar;

while ((theEntry = stream.GetNextEntry()) != null)

{

string directoryName = Path.GetDirectoryName(theEntry.Name);

string fileName = Path.GetFileName(theEntry.Name);

//生成解压目录

//Directory.CreateDirectory(directoryName);

if (directoryName != String.Empty)

{

if (Directory.Exists(DesPath + directoryName) && cover == false)

{

throw new Exception( "该文件已存在不能覆盖! "); return;

}

else

{

Directory.CreateDirectory(DesPath + directoryName);

cover = true;

}

}

if (fileName != String.Empty)

{

//解压文件到指定的目录

FileStream streamWriter = File.Create(DesPath + theEntry.Name);

int size = 2048;

byte[] data = new byte[2048];

while (true)

{

size = stream.Read(data, 0, data.Length);

if (size > 0)

{

streamWriter.Write(data, 0, size);

}

else

{

break;

}

}

streamWriter.Close();

}

}

stream.Close();

}

public void UnzipFiles(string SourceZip, string DesPath)

{

UnzipFiles(SourceZip, DesPath, false);

}

public void UnzipFiles(string SourceZip)

{

string DesPath = Path.GetDirectoryName(SourceZip);

UnzipFiles(SourceZip, DesPath, false);

}

}

}

这段代码我想直接用但不懂要调用什么头文件：
using System.IO.Compression;
//using System.IO.Compression.GZipStream;
using System.IO;
这样写这里都有错，ZipInputStream stream
该怎么写using 文件？



[解决办法]
ZipEntry、ZipInputStream是Java里的东东,C#里没有的.
VS2005,C#增加System.IO.Compression命名空间里的GZipStream,DeflateStream这两个类,提供压缩和解压

不太清楚，帮你顶下
