C# Zip压缩进度条怎么添加

在C#中实现Zip压缩进度条，可以通过使用System.IO.Compression.ZipArchive类来完成。以下是一个示例代码，其中通过使用System.IO.Compression.ZipArchive类来压缩文件，并通过Progress<T>类来实现进度条。

using System;using System.IO;using System.IO.Compression;using System.Threading.Tasks;using System.Net;using System.Windows.Forms;namespace ZipProgress{    public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }        private async void btnZip_Click(object sender, EventArgs e)        {            string zipPath = @"C:\Users\user\Desktop\test.zip";            string[] filesToZip = new string[] { @"C:\Users\user\Desktop\file1.txt", @"C:\Users\user\Desktop\file2.txt" };            progressBar1.Maximum = filesToZip.Length;            IProgress<int> progress = new Progress<int>(value =>            {                progressBar1.Value = value;            });            await Task.Run(() =>            {                using (FileStream zipToOpen = new FileStream(zipPath, FileMode.Create))                {                    using (ZipArchive archive = new ZipArchive(zipToOpen, ZipArchiveMode.Update))                    {                        for (int i = 0; i < filesToZip.Length; i++)                        {                            string fileToAdd = filesToZip[i];                            ZipArchiveEntry readmeEntry = archive.CreateEntry(Path.GetFileName(fileToAdd));                            using (Stream entryStream = readmeEntry.Open())                            using (Stream fileToCompress = File.OpenRead(fileToAdd))                            {                                fileToCompress.CopyTo(entryStream);                            }                            progress.Report(i + 1);                        }                    }                }            });            MessageBox.Show("Zip compression complete!");        }    }}

在上面的示例中，使用IProgress<int>接口来报告进度，并在压缩每个文件时更新进度条的值。最后，使用MessageBox显示压缩完成的消息。
