【转】C#打包文件夹成zip格式
C#打包文件夹成zip格式(包括文件夹和子文件夹下的所有文件)
C#打包zip文件可以调用现成的第三方dll,事半功倍,而且该dll完全免费,下载地址:SharpZipLib
下载完解压缩后,把 ICSharpCode.SharpZipLib.dll 拷贝到当前项目的目录下(如果偷懒的话,可以直接拷贝到当前项目的
bin\Debug目录下),在VS打开的项目引用上右键添加引用 ICSharpCode.SharpZipLib.dll
然后,在VS打开的项目上右键新建一个类,命名为 ZipHelper.cs,把类里面的所有code清空,复制以下代码,粘贴:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Diagnostics;
using ICSharpCode.SharpZipLib;
using ICSharpCode.SharpZipLib.Zip;
using ICSharpCode.SharpZipLib.Checksums;
using ICSharpCode.SharpZipLib.Core;
namespace ZipOneCode.ZipProvider
{
public class ZipHelper
{
/// <summary>
/// 压缩文件
/// </summary>
/// <param name="sourceFilePath"></param>
/// <param name="destinationZipFilePath"></param>
public static void CreateZip(string sourceFilePath, string destinationZipFilePath)
{
if (sourceFilePath[sourceFilePath.Length - 1] != System.IO.Path.DirectorySeparatorChar)
sourceFilePath += System.IO.Path.DirectorySeparatorChar;
ZipOutputStream zipStream = new ZipOutputStream(File.Create(destinationZipFilePath));
zipStream.SetLevel(6); // 压缩级别 0-9
CreateZipFiles(sourceFilePath, zipStream);
zipStream.Finish();
zipStream.Close();
}
/// <summary>

/// </summary>
/// <param name="sourceFilePath">待压缩的文件或文件夹路径</param>
/// <param name="zipStream">打包结果的zip文件路径(类似 D:\WorkSpace\a.zip),全路径包括文件名和.zip扩展名
</param>
/// <param name="staticFile"></param>
private static void CreateZipFiles(string sourceFilePath, ZipOutputStream zipStream)
{
Crc32 crc = new Crc32();
string[] filesArray = Directory.GetFileSystemEntries(sourceFilePath);
foreach (string file in filesArray)
{
if (Directory.Exists(file)) //如果当前是文件夹,递归
{
CreateZipFiles(file, zipStream);
}
else //如果是文件,开始压缩
{
FileStream fileStream = File.OpenRead(file);
byte[] buffer = new byte[fileStream.Length];
fileStream.Read(buffer, 0, buffer.Length);
string tempFile = file.Substring(sourceFilePath.LastIndexOf("\\") + 1);
ZipEntry entry = new ZipEntry(tempFile);
entry.DateTime = DateTime.Now;
entry.Size = fileStream.Length;
fileStream.Close();
crc.Reset();
crc.Update(buffer);
entry.Crc = crc.Value;
zipStream.PutNextEntry(entry);
zipStream.Write(buffer, 0, buffer.Length);
}
}
}
}
}
使用方法,在外部引用using ZipOneCode.ZipProvider 后,类似调用 ZipHelper.CreateZip(@"D:\Temp\forzip", @"D:\Temp2
\forzip.zip") 即可。
