C# ITextSharp在unity editor中运行良好，但在将应用程序构建到windows单机版时会生成损坏的0字节文件

下面的代码应该生成一个pdf，并将其保存在桌面上，其中包含unity编辑器中正常运行的内容，但最终的windows构建未能做到这一点。它生成了pdf并保存在桌面上，但pdf已损坏，显示0字节大小。我找不到错误，以下是代码：

 public void EnglishPdf()

    FileStream fs = new FileStream(Environment.GetFolderPath(Environment.SpecialFolder.Desktop)+ "\\Loshu-Numerology.pdf", FileMode.Create, FileAccess.Write, FileShare.None);

    doc.Open();

    doc.Close();

}

我遵循了一些与此类似的其他主题，但大多数主题最后都缺少doc.Close（），这在我的代码中不是这样的。我从一开始就有。我该如何解决这个问题

构建也成功构建，没有任何错误，并且一切运行正常。我猜代码中缺少了一些东西。任何帮助都会很有帮助。

升级到Itext7，它将被修复。谢谢
