关于c＃：iTextSharp使用Memorystream将PDF作为附件发送

iTextSharp send PDF as attachment using Memorystream

一直在挣扎，已经走得这么近了，但还不完全在那里。我正在尝试使用ITextSharp 4.1.2版以电子邮件附件的形式发送PDF。下面我提供的代码同时使用了filestream和memorystream，filestream是为了向我自己证明PDF模板上有数据(它是)。另外，我正在接收电子邮件，但没有附件。有人能看看我遗漏了什么吗？

1	public class BasePDFController : BaseController

{受保护的actionresult emailpdf(对象模型){字符串pdf=path.combine(server.mappath("~/infrastructure/pdfemplates/fw9.pdf"))；string outputfilepath=@"c:projects emp estu templateu filled.pdf"；

编辑：-是的，邮件提供商有问题。但我不知道如何修复它，或者这是否是最好的发送方式？写这篇文章的人显然放弃了。编辑修复了附件。

电子邮件已修复，我正在接收PDF！但是，当我尝试从电子邮件中打开PDF时，会收到一个错误：打开此文档时出错。文件已损坏，无法修复。思想？
