我有以下要求。需要在IFrame中显示Mime消息的html Body
看法
<iframe id="myIframe1" src="http://localhost:23245/Home/GetMimeMessageContent?FilePath=D \MimeFiles/htmlBody-small1.eml&PartName=HtmlBody" style="width:600px;height:600px;" >
控制器
public ActionResult GetMimeMessageContent(string filePath,string partName)
    {
        var mimeModel = BuildMimeModel(filePath, partName);
        MimeHeaderModel mimeHeadermodel = new MimeHeaderModel();
        mimeHeadermodel.FromAddress = mimeHeadermodel.ToAddress = mimeHeadermodel.Subject = string.Empty;
        mimeModel.MimeHeader = mimeHeadermodel;
        return View("MailDetailsView", mimeModel.MimeBody.HtmlBody);
    }
它没有在 Iframe 中显示 HtmlBody。但它调用控制器。我不知道我错过了什么。
