无法加载文件或程序集'；ICSharpCode.SharpZipLib'；或其依赖项之一.访问被拒绝

归档工作在办公室和网站的远程桌面（同事）上进行。我已经测试过了。

我正在写一个服务，我也需要这个里面。这在我的机器上不起作用，我远程工作，通过VPN连接。在此计算机上登录的用户属于域。

现在，在压缩之前，我用一个特殊的用户帐户进行模拟。如果我不这样做，那么这甚至不会在网站上工作。

以下是我得到的例外。我该怎么修？

以下是存档方法：

public bool ArchiveDirectory(string dirToArchive, string destDir, string archiveName)
        {
            bool ok = false;
            if (!String.IsNullOrWhiteSpace(dirToArchive) &&
                    !String.IsNullOrWhiteSpace(destDir) &&
                    !String.IsNullOrWhiteSpace(archiveName) &&
                    DirectoryExists(dirToArchive))
            {
                ok = true;
                //create destination directory
                if (!DirectoryExists(destDir))
                    ok = CreateDirectory(destDir);
            }
            if (ok)
            {
                //Archive Name should have .ZIP extension, if not, add it
                if (!archiveName.ToLowerInvariant().Contains(".zip"))
                    archiveName = archiveName + ".ZIP";
                //Check that the Zip file already exists, if it does then delete it
                if (FileExists(Path.Combine(destDir, archiveName)))
                    ok = FileDelete(Path.Combine(destDir, archiveName));
            }
            if (ok)
            {
                //Start Impersonation
                _impersonate.DoImpersonate();
                //Using ZipUtility Class to Zip Directory
                try
                {
                    ZipUtility.ZipFiles(dirToArchive, destDir, archiveName, "", true);
                }
                catch (SystemException ex)
                {
                    ok = false;
                }
                //end impersonation
                _impersonate.Dispose();
            }
            if (ok)
            {
                //double check that the archived directory exists
                ok = FileExists(Path.Combine(destDir, archiveName));
            }
            return ok;
        }

请注意，模拟正在像CreateDirectory、FileExists和FileDelete一样工作，没有任何问题。这3个方法在执行相关联的操作之前首先进行模拟。

谢谢你的调查！
