C# 发送带有附件的邮件

发布于 2024-10-19 13:39:49 字数 1385 浏览 4 评论 0 原文

我需要发送一封邮件，其中包含异常详细信息（黄屏死机）作为附件。

我可以得到 YSOD，如下所示：

string YSODmarkup = lastErrorWrapper.GetHtmlErrorMessage();
if (!string.IsNullOrEmpty(YSODmarkup))
{
    Attachment YSOD = Attachment.CreateAttachmentFromString(YSODmarkup, "YSOD.htm");
    mm.Attachments.Add(YSOD);
}

mm 的类型为 MailMessage，但邮件未发送。

这里

System.Net.Mail.MailMessage MyMailMessage = new System.Net.Mail.MailMessage("from", "to", "Exception-Details", htmlEmail.ToString());

用来绑定邮件正文。

此后仅添加附件。删除附件时，将发送邮件。

有人可以帮我吗？

根据阿尔宾先生和保罗先生的评论，我正在更新以下内容

        string YSODmarkup = Ex_Details.GetHtmlErrorMessage();
        string p = System.IO.Directory.GetCurrentDirectory();
        p = p + "\\trial.txt";
        StreamWriter sw = new StreamWriter(p);
        sw.WriteLine(YSODmarkup);
        sw.Close();
        Attachment a = new Attachment(p);       

        if (!string.IsNullOrEmpty(YSODmarkup))
        {
             Attachment  YSOD = Attachment.CreateAttachmentFromString(YSODmarkup, "YSOD.html");
            System.Net.Mail.Attachment(server.mappath("C:\\Documents and Settings\\user\\Desktop\\xml.docx"));

             MyMailMessage.Attachments.Add(a);

        }

，我将内容附加到文本文件中并尝试了相同的操作。所以邮件没有发出去。发送包含 HTML 标签的邮件是否有任何问题？因为我能够附加一个普通的文本文件。

原文

I need to send a mail including the exception details (Yellow Screen Of Death) as attachment.

I could get the YSOD as follows:

string YSODmarkup = lastErrorWrapper.GetHtmlErrorMessage();
if (!string.IsNullOrEmpty(YSODmarkup))
{
    Attachment YSOD = Attachment.CreateAttachmentFromString(YSODmarkup, "YSOD.htm");
    mm.Attachments.Add(YSOD);
}

mm is of type MailMessage, but the mail is not sent.

Here

System.Net.Mail.MailMessage MyMailMessage = new System.Net.Mail.MailMessage("from", "to", "Exception-Details", htmlEmail.ToString());

is used to bind the body of the mail.

After this only the attachment is added.
While removing the attachment, mail is sent.

Can anyone help me out?

As per the comments from Mr. Albin and Mr. Paul am updating the following

        string YSODmarkup = Ex_Details.GetHtmlErrorMessage();
        string p = System.IO.Directory.GetCurrentDirectory();
        p = p + "\\trial.txt";
        StreamWriter sw = new StreamWriter(p);
        sw.WriteLine(YSODmarkup);
        sw.Close();
        Attachment a = new Attachment(p);       

        if (!string.IsNullOrEmpty(YSODmarkup))
        {
             Attachment  YSOD = Attachment.CreateAttachmentFromString(YSODmarkup, "YSOD.html");
            System.Net.Mail.Attachment(server.mappath("C:\\Documents and Settings\\user\\Desktop\\xml.docx"));

             MyMailMessage.Attachments.Add(a);

        }

Here i attached the contents to a text file and tried the same. So the mail was not sent. Is there any issue with sending mails which contains HTML tags in it. Because i was able to attach a normal text file.
