我试图将iTextSharp pdf附加到Outlook MailItem,但实际添加附件始终会导致ArgumentException,附加信息只是说,"抱歉,出了点问题。您可能想再试一次。"
以下是相关代码:
public void SendPDF(string subject, string body, string To)
{
var pdf = GeneratePDF();
Outlook.Application mailApp = new Outlook.Application();
Outlook.MailItem mail = mailApp.CreateItem(Outlook.OlItemType.olMailItem) as Outlook.MailItem;
mail.Subject = subject;
mail.Body = body;
var addresses = To.Split(',');
foreach (var address in addresses)
{
mail.Recipients.Add(address);
}
//error happens here:
mail.Attachments.Add(pdf, Type.Missing, Type.Missing, EquipmentName + ".pdf");
mail.Recipients.ResolveAll();
mail.Send();
}
不附加pdf会导致成功发送电子邮件,但显然这会失败。创建pdf并将其存储在某处不是一种选择。任何帮助将不胜感激!

由Paul-Jan在评论中发布,使用Outlook无法附加内存中的pdf。我已切换到MailMessage。
