原文:基于ICSharpCode.SharpZipLib.Zip的压缩解压缩
今天记压缩解压缩的使用，是基于开源项目ICSharpCode.SharpZipLib.Zip的使用。
一、压缩：
/// <summary>
/// 压缩
/// </summary>
/// <param name="sourceDirectory"></param>
/// <param name="targetZipName"></param>
/// <param name="recurse"></param>
/// <param name="filter"></param>
/// <returns></returns>
public static void CreateZip(string zipFileName, string sourceDirectory, bool recurse=true, string fileFilter="")
{
if (string.IsNullOrEmpty(sourceDirectory))
{
throw new ArgumentNullException("SourceZipDirectory");
}
if (string.IsNullOrEmpty(zipFileName))
{
throw new ArgumentNullException("TargetZipName");
}
if (!Directory.Exists(sourceDirectory))
{
throw new DirectoryNotFoundException("SourceDirecotry");
}
if (Path.GetExtension(zipFileName).ToUpper() != ".ZIP")
throw new ArgumentException("TargetZipName is not zip");
FastZip fastZip = new FastZip();
fastZip.CreateZip(zipFileName, sourceDirectory, recurse, fileFilter);
}
二、解压缩：
/// <summary>
/// 解压
/// </summary>
/// <param name="zipFileName"></param>
/// <param name="targetDirectory"></param>
/// <param name="fileFilter"></param>
public static void ExtractZip(string zipFileName, string targetDirectory, string fileFilter="")
{
if (string.IsNullOrEmpty(zipFileName))
{
throw new ArgumentNullException("ZIPFileName");
}
if (!File.Exists(zipFileName))
{
throw new FileNotFoundException("zipFileName");
}
if (Path.GetExtension(zipFileName).ToUpper() != ".ZIP")
{
throw new ArgumentException("ZipFileName is not Zip ");
}
FastZip fastZip = new FastZip();
fastZip.ExtractZip(zipFileName, targetDirectory, fileFilter);
}
三、添加文件至压缩文件中
/// <summary>
/// 添加文件到压缩文件中
/// </summary>
/// <param name="zipFileName"></param>
/// <param name="filesNames"></param>
public static void AddFileToZip(string zipFileName, List<string> filesNames)
{
if (string.IsNullOrEmpty(zipFileName))
{
throw new ArgumentNullException("ZipName");
}
if (!File.Exists(zipFileName))
{
throw new FileNotFoundException("ZipName");
}
if (Path.GetExtension(zipFileName).ToUpper() != ".ZIP")
{
throw new ArgumentException("ZipFileName is not Zip ");
}
if(filesNames==null||filesNames.Count<)
return;
using (ZipFile zFile = new ZipFile(zipFileName))
{ zFile.BeginUpdate(); foreach (string fileName in filesNames)
{
zFile.Add(fileName);
} zFile.CommitUpdate();
} }
四、移除压缩文件中的文件
/// <summary>
/// 移除压缩文件中的文件
/// </summary>
/// <param name="zipName"></param>
/// <param name="fileNames"></param>
public static void DeleteFileFromZip(string zipFileName, IList<string> fileNames)
{
if (string.IsNullOrEmpty(zipFileName))
{
throw new ArgumentNullException("ZipName");
}
if (Path.GetExtension(zipFileName).ToUpper() != ".ZIP")
{
throw new ArgumentException("ZipName");
}
if(fileNames==null||fileNames.Count<)
{
return ;
}
using (ZipFile zipFile = new ZipFile(zipFileName))
{
zipFile.BeginUpdate();
foreach(string fileName in fileNames)
{
zipFile.Delete(fileName);
}
zipFile.CommitUpdate();
}
}
以上是基于ICSharpCode.SharpZipLib.Zip的部分使用，当然还有许多地方需要学习的。ICSharpCode.SharpZipLib.Zip使用起来比较快速方便，不想GZip那样对文件进行压缩时，还要进行复杂的操作。
今天就写这么多吧。
