用c#写一个压缩带密码的zip压缩文件，带进度百分比

在 C# 中，你可以使用 `System.IO.Compression.ZipFile` 类以及一些额外的步骤来创建一个压缩文件，并添加密码保护。这里是一个简单的示例，展示如何完成这个任务：

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

public class PasswordProtectedZip
{
    private static void CompressWithPassword(string sourcePath, string destinationPath, string password)
    {
        using (FileStream sourceStream = new FileStream(sourcePath, FileMode.Open))
        {
            byte[] passwordBytes = Encoding.UTF8.GetBytes(password);

            // 创建加密流
            using (MemoryStream encryptedStream = new MemoryStream())
            {
                using (ICryptoTransform encryptor = ProtectedData.CreateEncryptor(new RijndaelManaged(), passwordBytes, DataProtectionScope.LocalMachine))
                {
                    using (CryptoStream cs = new CryptoStream(encryptedStream, encryptor, CryptoStreamMode.Write))
                    {
                        ZipArchive archive = new ZipArchive(cs, ZipArchiveMode.Create, true);
                        ZipArchiveEntry entry = archive.CreateEntry(Path.GetFileName(sourcePath));
                        CopyStream(sourceStream, entry.Open());
                    }
                }

                // 将加密后的数据写入到新的压缩文件中
                File.WriteAllBytes(destinationPath, encryptedStream.ToArray());
            }
        }
    }

    public static void CopyStream(Stream source, Stream destination)
    {
        byte[] buffer = new byte[4096];
        int bytesRead;
        while ((bytesRead = source.Read(buffer, 0, buffer.Length)) > 0)
        {
            destination.Write(buffer, 0, bytesRead);
        }
    }

    public static void Main(string[] args)
    {
        string sourceFilePath = "source_file.txt";
        string zipFilePath = "password_protected.zip";
        string password = "example_password";

        try
        {
            Console.WriteLine("Compressing file...");
            CompressWithPassword(sourceFilePath, zipFilePath, password);
            Console.WriteLine($"Compression complete! {zipFilePath} is now encrypted with a password.");
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Error occurred: {ex.Message}");
        }
