使用C#将文件转换为单个zip

using System;
using System.IO;
using System.IO.Compression;

namespace ZipFileExample
{
    class Program
    {
        static void Main(string[] args)
        {
            string sourceDirectory = @"C:\example";
            string zipFilePath = @"C:\example.zip";

            // 如果zip文件已经存在，则删除它
            if (File.Exists(zipFilePath))
            {
                File.Delete(zipFilePath);
            }

            // 创建新的zip文件
            using (FileStream zipFileStream = new FileStream(zipFilePath, FileMode.Create))
            {
                using (ZipArchive zipArchive = new ZipArchive(zipFileStream, ZipArchiveMode.Create))
                {
                    // 将源目录中的所有文件添加到zip文件中
                    foreach (string filePath in Directory.GetFiles(sourceDirectory, "*", SearchOption.AllDirectories))
                    {
                        string relativePath = Path.GetRelativePath(sourceDirectory, filePath);
                        zipArchive.CreateEntryFromFile(filePath, relativePath);
                    }
                }
            }
        }
    }
}
