C＃背景工人与zipfile（Ionic.dll）

Question

因此，我一直试图反复尝试和错误，我似乎无法得到这个工作，基本上我想解压缩使用Ionic.DLL文件从http://dotnetzip.codeplex.com，你可以看到我也在这里做了一个线程：Extract ZipFile Using C# With Progress Report所以基本上总结了我后。

我有一个形式： 3xbuttons：btnCancel，btnBrowse和btnStart， 1xbackground工人：backgroundworker1 1xlabel：LABEL1 1xtextbox：textBox1的 1xprogressbar

       if (!Directory.Exists(INSTALL_LOCATION)) 
       {

          { 
           zip.ExtractAll(INSTALL_LOCATION, ExtractExistingFileAction.OverwriteSilently); 
          } 
       } 

       //If cancel button was pressed while the execution is in progress 
       //Change the state from cancellation ---> cancel'ed 
       if (m_oWorker.CancellationPending) 
       { 
        e.Cancel = true; 
        m_oWorker.ReportProgress(0); 
        return; 
       } 

      } 

      //Report 100% completion on operation completed 
      m_oWorker.ReportProgress(100); 
     } 

     private void btnStartAsyncOperation_Click(object sender, EventArgs e) 
     { 
      btnStartAsyncOperation.Enabled = false; 
      btnCancel.Enabled    = true; 
      //Start the async operation here 
      m_oWorker.RunWorkerAsync(); 
     } 

     private void btnCancel_Click(object sender, EventArgs e) 
     { 
      if (m_oWorker.IsBusy) 
      { 
       //Stop/Cancel the async operation here 
       m_oWorker.CancelAsync(); 
      } 
     } 
    } 
} 

什么，我想我的WinForms已经是简单地：浏览一个文件夹，然后点击开始（btnStart），它将启动压缩提取过程，该过程也显示在ProgressBar上（按时间显示），取消（btnCancel）按钮取消解压缩过程，我已成功完成所有操作，但不能弄清楚如何取消解压缩过程ss，它永远不会停止，除非我真的关闭.exe。我决定做一个没有文本框和浏览按钮的简单例子，这个例子在我之前提到的问题（上面的链接）中，但我没有看到如何实现一种方法来取消与后台工作人员的解压缩过程，以及我绝对需要使用后台工作，所以我可以有一个关于当前情况的进度报告等任何人都可以请适应我的例子或提供一个这样做的例子吗？

我发现了一个解决方案，我已经离开了Ionic并添加了现有的引用：System.IO.Compression和System.IO.Compression.FileSystem。
