【Asp.Net】如何在邮件正文粘贴图片

作者:sky3010 / 发布于2014/6/5/ 356

过.net应用程序调用Lotus Notes的COM组件来实现自动发送邮件的小程序，现在需要在邮件正文直接显示图片，而不是以附件的方式发送图片


	public Boolean SendNotesMail(object To, object copyTo, string subject, string location)
	 {
	 string from = ConfigurationManager.AppSettings["from"];
	 Domino.NotesSession ns = null;
	 Domino.NotesDatabase nd = null;
	 Domino.NotesDocument nDoc = null;
	 Domino.NotesMIMEEntity mime = null;
	 Domino.NotesMIMEHeader mimeHeader = null;
	 Domino.NotesMIMEEntity child = null;
	 NotesStream stream = null;
	 object itemValue = null;
	 string pw = "";
	 string serverName = "";
	 string mailFile = "";
	 string date = System.DateTime.Now.AddDays(-1).ToString("yyyy-MM-dd");
	 string[] sImage = { "pic1.gif", "pic2.gif", "test.xlsx" };
	 string sHtml = "<table border=\"0\" cellpadding=\"0\" cellspacing=\"0\" width=\"100%\" align=\"left\">"
	 + "<tr><td><img src=\"cid:" + sImage[0] + "\"></td></tr><tr><td><img src=\"cid:" + sImage[1] + "\"></td></tr></table>";
	 try
	 {
	 lock (this)
	 {
	 ns = new Domino.NotesSession();
	 pw = ConfigurationManager.AppSettings["fromPW"];
	 ns.Initialize(pw);

	 serverName = ConfigurationManager.AppSettings["mailServer"];
	 mailFile = "mail\\" + ConfigurationManager.AppSettings["fromJobcode"];
	 nd = ns.GetDatabase(serverName, mailFile, false);
	 if (!nd.IsOpen)
	 {
	 nd.Open();
	 }
	 nDoc = nd.CreateDocument();
	 nDoc.ReplaceItemValue("Form", "Memo");
	 nDoc.ReplaceItemValue("From", from);
	 nDoc.ReplaceItemValue("SendTo", To);

	 stream = ns.CreateStream();
	 mime = nDoc.CreateMIMEEntity("Body");
	 mimeHeader = mime.CreateHeader("Content-Type");
	 mimeHeader.SetHeaderVal("multipart/related");

	 //发送HTML格式文本
	 child = mime.CreateChildEntity(null);
	 stream.WriteText(sHtml,EOL_TYPE.EOL_NONE);
	 child.SetContentFromText(stream, "text/html;charset=gb2312", MIME_ENCODING.ENC_NONE);
	 stream.Close();

	 //发送图片
	 child = mime.CreateChildEntity(null);
	 mimeHeader = child.CreateHeader("Content-ID");
	 mimeHeader.SetHeaderVal(sImage[0]);
	 if (stream.Open(Directory.GetCurrentDirectory() + "[url=file://\\pic\\]\\pic\\[/url]" + sImage[0], "binary"))
	 {
	 if (stream.Bytes != 0)
	 child.SetContentFromBytes(stream, "image/jpeg;name=\"" + sImage[0] + "\"", MIME_ENCODING.ENC_IDENTITY_BINARY);
	 }
	 stream.Close();
	 child = mime.CreateChildEntity(null);
	 mimeHeader = child.CreateHeader("Content-ID");
	 mimeHeader.SetHeaderVal(sImage[1]);
	 if (stream.Open(Directory.GetCurrentDirectory() + "[url=file://\\pic\\]\\pic\\[/url]" + sImage[1], "binary"))
	 {
	 if (stream.Bytes != 0)
	 child.SetContentFromBytes(stream, "image/jpeg;name=\"" + sImage[1] + "\"", MIME_ENCODING.ENC_IDENTITY_BINARY);

	 stream.Close();

	 //添加附件
