脚本任务SSIS 2008中的SharpZipLib错误

Question

我正在尝试创建一个脚本，它可以在动态中对任何文件进行压缩。为此，我使用了一个DLL SharpZipLib。但无法运行软件包。下面是我在互联网上找到的代码，我在脚本任务控件中作为示例使用了这些代码。

===========================================

使用系统；使用ICSharpCode.SharpZipLib.Zip.Compression.Streams；；使用Microsoft.SqlServer.Dts.Runtime；使用System.Windows.Forms；使用ICSharpCode.SharpZipLib.Checksums；使用ICSharpCode.SharpZipLib.Zip；使用ICSharpCode.SharpZipLib.Zip；使用ICSharpCode.SharpZipLib.Core；使用System.IO；

公空主(){

        CreateSample("D:\\TestZipResult\\", "D:\\TestZipTarget\\");            

        // TODO: Add your code here
        Dts.TaskResult = (int)ScriptResults.Success;

    }

//压缩指定文件夹中的文件，并在名为outPathname的磁盘上创建一个zip文件。//

    public void CreateSample(string outPathname, string folderName)
    {

        FileStream fsOut = File.Create(outPathname);
        ZipOutputStream zipStream = new ZipOutputStream(fsOut);

        zipStream.SetLevel(3); //0-9, 9 being the highest level of compression


        // This setting will strip the leading part of the folder path in the entries, to
        // make the entries relative to the starting folder.
        // To include the full path for each entry up to the drive root, assign folderOffset = 0.
        int folderOffset = folderName.Length + (folderName.EndsWith("\\") ? 0 : 1);

        CompressFolder(folderName, zipStream, folderOffset);

        zipStream.IsStreamOwner = true; // Makes the Close also Close the underlying stream
        zipStream.Close();

    }

    // Recurses down the folder structure
    //
    private void CompressFolder(string path, ZipOutputStream zipStream, int folderOffset)
    {

        string[] files = Directory.GetFiles(path);

        foreach (string filename in files)
        {

            FileInfo fi = new FileInfo(filename);

            string entryName = filename.Substring(folderOffset); // Makes the name in zip based on the folder
            entryName = ZipEntry.CleanName(entryName); // Removes drive from name and fixes slash direction
            ZipEntry newEntry = new ZipEntry(entryName);
            newEntry.DateTime = fi.LastWriteTime; // Note the zip format stores 2 second granularity

            // Specifying the AESKeySize triggers AES encryption. Allowable values are 0 (off), 128 or 256.
            //   newEntry.AESKeySize = 256;

            // To permit the zip to be unpacked by built-in extractor in WinXP and Server2003, WinZip 8, Java, and other older code,
            // you need to do one of the following: Specify UseZip64.Off, or set the Size.
            // If the file may be bigger than 4GB, or you do not need WinXP built-in compatibility, you do not need either,
            // but the zip will be in Zip64 format which not all utilities can understand.
            //   zipStream.UseZip64 = UseZip64.Off;
            newEntry.Size = fi.Length;

            zipStream.PutNextEntry(newEntry);

            // Zip the file in buffered chunks
            // the "using" will close the stream even if an exception occurs
            byte[] buffer = new byte[4096];
            using (FileStream streamReader = File.OpenRead(filename))
            {
                StreamUtils.Copy(streamReader, zipStream, buffer);
            }
            zipStream.CloseEntry();
        }
        string[] folders = Directory.GetDirectories(path);
        foreach (string folder in folders)
        {
            CompressFolder(folder, zipStream, folderOffset);
        }

    }

===========================================

下面是我正在得到的一个错误，但是正确地添加了对DLL的引用。

===========================================错误: System.Reflection.TargetInvocationException:异常已被调用的目标抛出。-> System.IO.FileNotFoundException:无法加载文件或程序集'ICSharpCode.SharpZipLib、Version=0.86.0.518、Culture=neutral、PublicKeyToken=1b03e6acf1164f73‘或其依赖项之一。系统找不到指定的文件。文件名：'ICSharpCode.SharpZipLib，Version=0.86.0.518，Culture=neutral，PublicKeyToken=1b03e6acf1164f73‘

===========================================

如果有人能帮我解决这件事，我将不胜感激。

你好，F. Ahmed

我不知道如何使用SharpZipLib来完成这个任务--看起来找到程序集存在一个问题。你试过去参加大会吗？

也就是说，对于http://www.nsoftware.com/ssis/上的SSIS压缩任务来说，这应该是一个简单的任务。
