基于C#实现压缩和解压文件及文件夹
目录
- 使用ZipFile
- 使用ZipArchive
- 使用SharpZipLib
- 使用第三方压缩软件
C#压缩和解压文件及文件夹有以下几种方式：
ZipFile(.NET 4.5 System.IO.Compression命名空间中新提供的压缩类)
ZipArchive
SharpZipLib和DotNetZip
使用第三方压缩软件
使用ZipFile
引用.NET 4.5程序集：System.IO.Compression 和 System.IO.Compression.FileSystem.
public class CompressionHelper
{
/// <summary>
/// 将指定目录压缩为Zip文件

}
if (!directoryInfo.Exists)编程客栈
{
directoryInfo.Create();
}
System.IO.Compression.ZipFile.CreateFromDirectory(folderPath, zipPath, CompressionLevel.Optimal, false);
}
/// <summary>

public static void CompressFileZip(string filePath, string zipPath)
{

string dirPath = fileInfo.DirectoryName?.Replace("\\", "/") + "/";
string tempPath = dirPath + Guid.NewGuid() + "_temp/";
if (!Directory.Exists(tempPath))

}
fileInfo.CopyTo(tempPath + fileInfo.Name);
CompressDirectoryZip(tempPath, zipPath);
DirectoryInfo directory = new DirectoryInfo(tempPath);

{
//将文件夹属性设置为普通,如：只读文件夹设置为普通
directory.Attributes = FileAttributes.Normal;
directory.Delete(true);
}

if (!directoryInfo.Exists)
{

}
System.IO.Compression.ZipFile.ExtractToDirectory(zipPath, folderPath);
}
}
使用ZipArchive
public class ZipArchiveHelper
{
public static void ZipFile(string sourceFilePath, string zipFilePath)
{
System.IO.Compression.ZipFile.CreateFromDirectory(sourceFilePath, zipFilePath);
// 创建并添加被压缩文件

ZipArchiveEntry readMeEntry = archive.CreateEntry(filename);
using (System.IO.Stream stream = readMeEntry.Open())
{
byte[] bytes = System.IO.File.ReadAllBytes(zipFilePath);
stream.Write(bytes, 0, bytes.Length);
}
}
}
}
/// <summary>

public static void AddzipFile(string sourceFilePath, string zipFilePath)

ZipArchiveEntry readMeEntry = archive.CreateEntry(filename);
using (System.IO.Stream stream = readMeEntry.Open())
{
byte[] bytes = System.IO.File.ReadAllBytes(sourceFilePath);
stream.Write(bytes, 0, bytes.Length);
}
}
}
}
/// <summary>
/// 解压压缩文件
/// </summary>
/// <param name="zipFilePath"></param>

public static void UzipFile(string zipFilePath, string unzipFilePath)

{
using (FileStream fsout = File.Create(System.IO.Path.Combine(unzipFilePath, et.Name)))
{

}
}
}
}
}
}
}
