在C#中并行压缩文件夹的最佳解决方案是使用System.IO.Compression
命名空间中的ZipFile
类。以下是一个包含代码示例的解决方案:
using System;
using System.IO;
using System.IO.Compression;
using System.Threading.Tasks;
public class ParallelZip
{
public static void Main()
{
string sourceFolderPath = @"C:\SourceFolder";
string destinationFolderPath = @"C:\DestinationFolder\archive.zip";
ParallelZipFolder(sourceFolderPath, destinationFolderPath);
}
public static void ParallelZipFolder(string sourceFolderPath, string destinationFolderPath)
{
// Create the destination folder if it doesn't exist
Directory.CreateDirectory(Path.GetDirectoryName(destinationFolderPath));
// Get all files in the source folder
string[] files = Directory.GetFiles(sourceFolderPath, "*", SearchOption.AllDirectories);
// Use Parallel.ForEach to process each file in parallel
Parallel.ForEach(files, (filePath) =>
{
// Calculate the relative path of the file within the source folder
string relativePath = filePath.Substring(sourceFolderPath.Length + 1);
// Create the entry name for the file in the zip archive
string entryName = Path.Combine(Path.GetFileName(sourceFolderPath), relativePath);
// Create the entry name for the file in the zip archive
string entryPath = Path.Combine(Path.GetDirectoryName(destinationFolderPath), entryName);
// Create the directory structure for the entry if it doesn't exist
Directory.CreateDirectory(Path.GetDirectoryName(entryPath));
// Compress the file and add it to the zip archive
using (FileStream sourceStream = new FileStream(filePath, FileMode.Open, FileAccess.Read, FileShare.Read))
using (FileStream destinationStream = new FileStream(entryPath, FileMode.Create, FileAccess.Write, FileShare.None))
using (ZipArchive archive = new ZipArchive(destinationStream, ZipArchiveMode.Update))
{
ZipArchiveEntry entry = archive.CreateEntry(entryName);
using (Stream entryStream = entry.Open())
{
sourceStream.CopyTo(entryStream);
}
}
Console.WriteLine($"Compressed {filePath}");
});
}
}
上述代码将指定的源文件夹中的所有文件并行压缩到指定的zip文件夹中。请将sourceFolderPath
和destinationFolderPath
更改为实际的文件夹路径。此代码使用Parallel.ForEach
方法来并行处理每个文件。每个文件都被压缩并添加到zip文件夹中。在控制台上,将输出每个压缩文件的路径。
