如何在.NET HTML邮件中嵌入图像？

试试这个:

LinkedResource objLinkedRes = new LinkedResource(
            Server.MapPath(".") + "\\fuzzydev-logo.jpg", 
            "image/jpeg");
objLinkedRes.ContentId = "fuzzydev-logo";       
AlternateView objHTLMAltView = AlternateView.CreateAlternateViewFromString(
            "", 
            new System.Net.Mime.ContentType("text/html"));
objHTLMAltView.LinkedResources.Add(objLinkedRes);
objMailMessage.AlternateViews.Add(objHTLMAltView);
