1、通過 System.IO.Compression 命名空間中新增的ZipArchive、ZipFile等類實現(xiàn)。
不需要安裝第三方的組件包，微軟官方的實現(xiàn)，推薦使用
//壓縮
System.IO.Compression.ZipFile.CreateFromDirectory(@"C:\Users\Pride\Pictures\test\123", @"C:\Users\Pride\Pictures\test\123.zip");
//解壓
System.IO.Compression.ZipFile.ExtractToDirectory(@"C:\Users\Pride\Pictures\test\123.zip", @"C:\Users\Pride\Pictures\test\1234");
2、第三方類庫(DotNetZip的使用)
? SharpZipLib[1]
? DotNetZip[2]
DotNetZip的簡單使用
壓縮文件
using (ZipFile zip = new ZipFile())
{
zip.AddFile("c:\\photos\\personal\\7440-N49th.png");
zip.AddFile("c:\\Desktop\\2005_Annual_Report.pdf");
zip.AddFile("ReadMe.txt");
zip.Save("Archive.zip");
}
更新文件，無需解壓
using (ZipFile zip = ZipFile.Read("ExistingArchive.zip"))
{
// 1. remove an entry, given the name
zip.RemoveEntry("README.txt");
// 2. Update an existing entry, with content from the filesystem
zip.UpdateItem("Portfolio.doc");
// 3. modify the filename of an existing entry
// (rename it and move it to a sub directory)
ZipEntry e = zip["Table1.jpg"];
e.FileName ="images/Figure1.jpg";
// 4. insert or modify the comment on the zip archive
zip.Comment ="This zip archive was updated" + System.DateTime.ToString("G");
// 5. finally, save the modified archive
zip.Save();
}
提取文件
using (ZipFile zip = ZipFile.Read("ExistingZipFile.zip"))
{
foreach (ZipEntry e in zip)
{
e.Extract(TargetDirectory, true); // true => overwrite existing files
}
}
3、原生 System.IO.Compression 實現(xiàn) zip 的壓縮與解壓
不需要安裝第三方的組件包，微軟官方的實現(xiàn)，需要添加命名空間using System.IO.Compression;
將指定目錄壓縮為Zip文件
/// <summary>
/// 將指定目錄壓縮為Zip文件
/// </summary>
/// <param name="folderPath">文件夾地址 D:/1/ </param>
/// <param name="zipPath">zip地址 D:/1.zip </param>
public static void CompressDirectoryZip(string folderPath, string zipPath)
{
DirectoryInfo directoryInfo = new(zipPath);
if (directoryInfo.Parent != null)
{
directoryInfo = directoryInfo.Parent;
}
if (!directoryInfo.Exists)
{
directoryInfo.Create();
}
ZipFile.CreateFromDirectory(folderPath, zipPath, CompressionLevel.Optimal, false);
}
將指定文件壓縮為Zip文件
/// <summary>
/// 將指定文件壓縮為Zip文件
/// </summary>
/// <param name="filePath">文件地址 D:/1.txt </param>
/// <param name="zipPath">zip地址 D:/1.zip </param>
public static void CompressFileZip(string filePath, string zipPath)
{
FileInfo fileInfo = new FileInfo(filePath);
string dirPath = fileInfo.DirectoryName?.Replace("\\", "/") + "/";
string tempPath = dirPath + Guid.NewGuid() + "_temp/";
if (!Directory.Exists(tempPath))
{
Directory.CreateDirectory(tempPath);
}
fileInfo.CopyTo(tempPath + fileInfo.Name);
CompressDirectoryZip(tempPath, zipPath);
DirectoryInfo directory = new(path);
if (directory.Exists)
{
//將文件夾屬性設(shè)置為普通,如：只讀文件夾設(shè)置為普通
directory.Attributes = FileAttributes.Normal;
directory.Delete(true);
}
}
解壓Zip文件到指定目錄(壓縮單個文件的邏輯其實就是先將我們要壓縮的文件復(fù)制到一個臨時目錄，然后對臨時目錄執(zhí)行了壓縮動作，壓縮完成之后又刪除了臨時目錄)
/// <summary>
/// 解壓Zip文件到指定目錄
/// </summary>
/// <param name="zipPath">zip地址 D:/1.zip</param>
/// <param name="folderPath">文件夾地址 D:/1/</param>
public static void DecompressZip(string zipPath, string folderPath)
{
DirectoryInfo directoryInfo = new(folderPath);
if (!directoryInfo.Exists)
{
directoryInfo.Create();
}
ZipFile.ExtractToDirectory(zipPath, folderPath);
}
復(fù)制
