Question

我正在尝试发送通过iCal.net生成的.ics文件。在Outlook中打开文件很好，并且具有我尝试通过MailKit发送的图像附件，但是在通过Mailkit发送时，图像不存在。

然后尝试发送以下代码：

       var ical = new TextPart("calendar")
        {
            ContentTransferEncoding = ContentEncoding.Default,
            ContentDisposition = new ContentDisposition (ContentDisposition.Inline),
            Text = calendar
        };

        ical.ContentType.Parameters.Add("method", "REQUEST");
        message.Body = ical;

任何帮助将不胜感激。

谢谢

我可以很好地接受/拒绝日历邀请，但是通过电子邮件，附件不会显示。

Answer 1

根据我从Outlook发送给我的示例会议请求，Outlook不会在NodeList neighbors = priceFactorNode.getChildNodes(); Node unwantedNode = neighbors.item(1); NodeList children = unwantedNode.getChildNodes(); priceFactorNode.removeChild(unwantedNode); for(int x = 0; x < children.getLength(); x++) { priceFactorNode.appendChild(children.item(x)); }部分中添加Content-Disposition。

它也以base64编码。

尝试一下：

text/calendar

我还注意到Outlook倾向于使用以下结构构造MIME消息（可能需要也可能不需要）：

var ical = new TextPart("calendar")
{
    ContentTransferEncoding = ContentEncoding.Base64,
    Text = calendar
};

ical.ContentType.Parameters.Add("method", "REQUEST");

无法通过MailKit发送带有图片附件的iCal.net
