C# 如何将生成的PDF附加到.NET SMTP？

我正在使用PDFsharp生成作业报告。我需要将该报告自动附加到发送的电子邮件中。现在，当用户以角度模式查看职务信息时，他们单击“电子邮件”，生成报告，并显示一个新模式和电子邮件输入字段。如何设置电子邮件控制器以在JobSetupPdfs文件夹中找到正确的PDF

PDF控制器

public string Get(int id = 1)
    {

        JobDataAdapter adapter = new JobDataAdapter();
        Job job = new Job();
        job = adapter.GetJob(id);
        if (job == null)
        {
            return string.Empty;
        }

        try
        {
        // Create a new PDF document
            PdfDocument document = new PdfDocument();
            document.Info.Title = "Created with PDFsharp";

         gfx.DrawString("Texas Exterior Systems", HeadingFont, XBrushes.Black,

更新 好的，我用正确的路径设置了它。现在，我如何让它附加刚刚生成的PDF？我是否需要在PDF中添加时间戳，并将msg.Attachments附加到该文件夹中最新的PDF

 msg.Attachments.Add(new Attachment(@"C:\Users\texas_000\Desktop\TexasExterior\TexasExterior\JobSetupPdfs\Restoration.pdf"));

您可以在邮件对象上使用附件集合

msg.Attachments.Add（新附件（PathToAttachment））

您可以将流的内容添加为附件。PDFsharp可以将PDF文件保存到流中。@user3919120请参见上文，使用文件流作为附件。出于调试目的，在开发和附加文件时保存文件可能更容易。然而，真正的生产方式是使用流。
