拒绝访问 .tmp 路径

我正在尝试使用 DotNetZip 库压缩文件。我正在从文件中读取路径并将 zip 保存到该文件。但程序崩溃并抛出。这是我的代码：

using (ZipFile zip = new ZipFile())
{
   zip.AddDirectory(dir + "\\OUTPUT_FOLDERS");

   StreamReader sr = new StreamReader(dir + "\\Tools\\SettingsForPath");
   string path = sr.ReadToEnd();
   sr.Close();

   zip.Save(path + "\\SavedZip.zip");
   Directory.Delete(dir + "\\OUTPUT_FOLDERS", true);
}

这是我的错误：

System.UnauthorizedAccessException: Access to the path 'C:\Users\DotNetZip-nvan5kb5.tmp' is denied.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy, Boolean useLongPath, Boolean checkHost)

您正在尝试写信给C:\Users目录，而您无权执行此操作。

Use Path.GetTempPath()获取可以写入的目录的名称。

See http://msdn.microsoft.com/en-us/library/system.io.path.gettemppath.aspx http://msdn.microsoft.com/en-us/library/system.io.path.gettemppath.aspx了解更多信息。

您可以按如下方式使用它：

using (ZipFile zip = new ZipFile())
{
    zip.TempFileFolder = System.IO.Path.GetTempPath();

    // etc.
