我有一个 asp.net MVC 3 Web应用程序，在某些页面中我显示了一个条形图。
现在用户在该页面中询问"mailto"类型的链接，单击该链接时，电子邮件客户端应该打开，其中TO，主题和正文将自动填充，条形图应出现在正文中。
我知道"mailto"有限制，我们可以像下面这样用简单的文本准备正文，但是有什么解决方法可以将图形放在电子邮件正文中吗？

mailto协议非常有限。您可能需要从服务器发送电子邮件。
using Microsoft.Office.Interop.Outlook;
public void Sendemail()
{
try
{
Application oApp = new Application();
MailItem oMsg = (MailItem)(oApp.CreateItem(OlItemType.olMailItem));
// Set HTMLBody.
const string emailSubject = "Auto Generated Email:Graph Screen Shot Update for";
const string sDisplayName = "MyAttachment";
const int iPosition = 50; //
const int iAttachType = (int)OlAttachmentType.olByValue;
string htmlStart = "<html><body><h5><Font Color=Purpel>Hi,<br/>Please Find below The screen shot as of " + DateTime.Now + "<br/></h5>";
string body = string.Empty;
Microsoft.Office.Interop.Outlook.Attachment oAttach = oMsg.Attachments.Add(@"c:Appsdownload.jpg", iAttachType, iPosition, sDisplayName);
body += "<img src="cid:" + oAttach.FileName + "" /><br/>";
string wholeBody = htmlStart + body + "<h5><Font Color=Purpel>Note:Please check the graph.<br/>Regards,<br/>Md. Ajmal<br/><br/></h5></body></html>";
oMsg.HTMLBody = wholeBody;
// Set the subject.
oMsg.Subject = emailSubject;
//display
oMsg.Display(oMsg);
// Clean up.
oMsg = null;
oApp = null;
