我改编了这篇文章中的代码来制作一个压缩和复制目录的程序。我在我的代码中包含了一个后台工作程序，因此我可以异步运行压缩例程以防止界面冻结。这是我改编的代码：
private void StartZipping()
{
var zipWorker = new BackgroundWorker { WorkerReportsProgress = true };
zipWorker.DoWork += ZipWorkerWork;
zipWorker.RunWorkerCompleted += ZipWorkerCompleted;
zipWorker.RunWorkerAsync();
}
private void ZipWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
WriteLogEntry("Zip Worker Finished");
var sleep = new Timer();
sleep.Tick += SleepTick;
sleep.Interval = DEBUG ? SecondsToMilliseconds(45) : MinutesToMilliseconds(15);
sleep.Start();
}
private void ZipWorkerWork(object sender, DoWorkEventArgs e)
{
WriteLogEntry("Zip Worker Started");
var checkedItems = GetCheckedItems();
if (checkedItems.Count() <= 0) return;
foreach (var p in checkedItems)
ZipFiles(((BackupProgram)p.Tag));
}
private static void ZipFiles(BackupProgram program)
{
var zipPath = string.Format("{0}{1}.ZIP", TempZipDirectory, program.Name.ToUpper());
WriteLogEntry(string.Format("Zipping files from '{0}' to '{1}'...", program.Path, zipPath));
try
{
var emptyzip = new byte[] { 80, 75, 5, 6, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };
if (File.Exists(zipPath)) File.Delete(zipPath);
var fs = File.Create(zipPath);
fs.Write(emptyzip, 0, emptyzip.Length);
fs.Flush();
fs.Close();
//fs = null;
//Copy a folder and its contents into the newly created zip file
var sc = new Shell32.ShellClass();
var srcFlder = sc.NameSpace(program.Path);
var destFlder = sc.NameSpace(zipPath);
var items = srcFlder.Items();
destFlder.CopyHere(items, 20);
//sc = null;
System.Threading.Thread.Sleep(1000);
ZippedPrograms.Add(zipPath);
WriteLogEntry("Zip Succeeded");
}
catch (Exception ex)
{
WriteLogEntry(string.Format("Zipping Failed: {0} >> {1}", ex.Message, ex.InnerException.Message));
MessageBox.Show(ex.InnerException.Message, ex.Message);
}
}
internal class BackupProgram
{
public string Name { get; set; }
public string Path { get; set; }
public BackupProgram(string name, string path)
{
Name = name;
Path = path;
}
}
显然，就目前而言，所有压缩窗口都会在命中此代码时显示。我试图模仿示例程序（隐藏窗口），但只取得了微不足道的成功。窗户被隐藏了，但拉链只完成了部分。这是修改后的代码，其行为与文章的几乎相同：
private static void ZipFiles(BackupProgram program)
{
try
{
var zipPath = string.Format("{0}{1}.ZIP", TempZipDirectory, program.Name.ToUpper());
var i = new ProcessStartInfo(AppDomain.CurrentDomain.BaseDirectory + "zip.exe");
i.Arguments = string.Format("\"{0}\" \"{1}\"", program.Path, zipPath);
//i.CreateNoWindow = false;
//i.WindowStyle = ProcessWindowStyle.Normal;
i.CreateNoWindow = true;
i.WindowStyle = ProcessWindowStyle.Hidden;
if (File.Exists(zipPath))
{
WriteLogEntry(string.Format("'{0}' exists, deleting...",zipPath));
File.Delete(zipPath);
}
var process = Process.Start(i);
WriteLogEntry(string.Format("Zipping files from '{0}' to '{1}'...", program.Path, zipPath));
process.WaitForExit();
ZippedPrograms.Add(zipPath);
WriteLogEntry("Zip Succeeded");
}
catch (Exception ex)
{
WriteLogEntry(string.Format("Zipping Failed: {0} >> {1}", ex.Message, ex.InnerException.Message));
MessageBox.Show(ex.InnerException.Message, ex.Message);
}
}
我想知道的是：有没有办法使用我原来的改编代码，但隐藏进度窗口？
谢谢！

以下是示例解决方案的代码（可从文章顶部的链接下载），即 zip.exe：
using System;
using System.IO;
namespace zip
{
/// <summary>
/// Summary description for Class1.
/// </summary>
class Class1
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main(string[] args)
{
//Create an empty zip file
byte[] emptyzip = new byte[] { 80, 75, 5, 6, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };
FileStream fs = File.Create(args[1]);
fs.Write(emptyzip, 0, emptyzip.Length);
fs.Flush();
fs.Close();
fs = null;
//Copy a folder and its contents into the newly created zip file
Shell32.ShellClass sc = new Shell32.ShellClass();
Shell32.Folder SrcFlder = sc.NameSpace(args[0]);
Shell32.Folder DestFlder = sc.NameSpace(args[1]);
Shell32.FolderItems items = SrcFlder.Items();
DestFlder.CopyHere(items, 20);
//Ziping a file using the Windows Shell API creates another thread where the zipping is executed.
//This means that it is possible that this console app would end before the zipping thread
//starts to execute which would cause the zip to never occur and you will end up with just
//an empty zip file. So wait a second and give the zipping thread time to get started
System.Threading.Thread.Sleep(1000);
}
}
}
