Asp.net mvc 3 Can'；我不知道如何使用MvcMailer进行附件

如何以及在何处放置字符串的实际文件位置

attachmentPath

：

public virtual MailMessage Welcome(string attachmentPath)
    {
        var mailMessage = new MailMessage{Subject = "Welcome to MvcMailer"};
        ...
        mailMessage.Attachments.Add(new Attachment(attachmentPath));
        PopulateBody(mailMessage, "Welcome");
        return mailMessage;
    }

假定服务器上的物理文件位置为

c:\inetpub\server\website\docs\test.pdf

您可以执行以下操作：

mailMessage.Attachments.Add(new Attachment((Path.Combine(AppDomain.CurrentDomain.BaseDirectory) + "\docs\") + attachmentFile))

其中attachmentFile是您的文件

test.pdf

---

c:\inetpub\server\website\docs\test.pdf

只需将attachmentPath替换为@“c:\inetpub\server\website\docs\test.pdf”，如下所示：

mailMessage.Attachments.Add(new Attachment((Path.Combine(AppDomain.CurrentDomain.BaseDirectory) + "\docs\") + attachmentFile))

mailMessage.Attachments.Add(new Attachment(@"c:\inetpub\server\website\docs\test.pdf"));

更改附件路径

mailMessage.Attachments.Add(new Attachment(attachmentPath));

至@“c:\inetpub\server\website\docs\test.pdf”

很抱歉反应太晚。我到底在哪里“声明”（如果是这样的话）

attachmentFile

？我如何“申报”呢？
