使用密码C＃压缩文本文件

Question

我是C＃的新手，想要用密码压缩文件。谷歌搜索后我找到了关于DotNetZip并尝试了以下但它不起作用。我可以尝试使用c＃中的密码压缩其他选项吗？

using Ionic.Zip;

namespace CSLab
{
  class Program
  {
     static void Main(string[] args)
     {
       using (ZipFile zip = new ZipFile())
       {
         zip.Password = "password";
         zip.AddDirectory("./test");
         zip.Save("a.zip");
       }
     }
   }
 }
