Answer 2

下面是我实现的。protected void OnZip(object sender, EventArgs e)
{
    string path = base.Server.MapPath(this.tbZipFolder.Text);
    if (Directory.Exists(path))
    {
        if (!path.EndsWith(@"\"))
        {
            path = path + @"\";
        }
        try
        {
            string str2 = base.Server.MapPath(this.tbZipFolderTo.Text);
            if (!Directory.Exists(Path.GetDirectoryName(str2)))
            {
                Directory.CreateDirectory(Path.GetDirectoryName(str2));
            }
            string[] strArray = Directory.GetFiles(path, "*.*", SearchOption.AllDirectories);
            string[] strArray2 = Directory.GetDirectories(path, "*", SearchOption.AllDirectories);
            using (ZipOutputStream stream = new ZipOutputStream(File.Create(str2)))
            {
                ZipEntry entry;
                stream.SetLevel(9);
                byte[] buffer = new byte[0x1000];
                foreach (string str3 in strArray2)
                {
                    entry = new ZipEntry(str3.Remove(0, path.Length) + @"\");
                    entry.set_DateTime(DateTime.Now);
                    stream.PutNextEntry(entry);
                }
                foreach (string str4 in strArray)
                {
                    entry = new ZipEntry(str4.Remove(0, path.Length));
                    entry.set_DateTime(DateTime.Now);
                    stream.PutNextEntry(entry);
                    using (FileStream stream2 = File.OpenRead(str4))
                    {
                        int num;
                        do
                        {
                            num = stream2.Read(buffer, 0, buffer.Length);
                            stream.Write(buffer, 0, num);
                        }
                        while (num > 0);
                    }
                }
                stream.Finish();
                stream.Close();
            }
            this.labelMsg.Text = string.Format("压缩目录[{0}]到文件[{1}]成功", this.tbZipFolder.Text, this.tbZipFolderTo.Text);
        }
        catch (Exception exception)
        {
            this.labelMsg.Text = exception.Message;
        }
    }
    else
    {
        this.labelMsg.Text = string.Format("目录[{0}]不存在", this.tbZipFolder.Text);
    }
}
