使用asp.net发送邮件和嵌入式图像
我已经使用了以下但它无法正常工作
Dim EM As System.Net.Mail.MailMessage = New System.Net.Mail.MailMessage(txtFrom.Text, txtTo.Text)
Dim A As System.Net.Mail.Attachment = New System.Net.Mail.Attachment(txtImagePath.Text)
Dim RGen As Random = New Random()
A.ContentId = RGen.Next(100000, 9999999).ToString()
EM.Attachments.Add(A)
EM.Subject = txtSubject.Text
EM.Body = "<body>" + txtBody.Text + "<br><img src='cid:" + A.ContentId +"'></body>"
EM.IsBodyHtml = True
Dim SC As System.Net.Mail.SmtpClient = New System.Net.Mail.SmtpClient(txtSMTPServer.Text)
SC.Send(EM)
我正在编写一个程序,向用户发送电子邮件,其中包含嵌入电子邮件正文(HTML)中的多个图像(图表).
当我尝试这里的样本时......当我只需要嵌入一个图像http://www.systemnetmail.com/faq/4.4.aspx时效果很好 .
但是,当我尝试使用以下代码嵌入多个图像时,没有嵌入任何图像,而是将它们作为附件发送.
public MailMessage MailMessage(Metric metric, DateTime date)
{
MailMessage msg = new MailMessage();
msg.From = new MailAddress("test@gmail.com", "User1");
msg.To.Add(new MailAddress("test@gmail.com"));
msg.Subject = "Trend for metric: " + metric.Name;
msg.IsBodyHtml = true;
// Generate the charts for the given metric
var charts = this.GenerateCharts(metric, date);
int i = 0;
string htmlBody = "<html><body>";
List<LinkedResource> resources = new List<LinkedResource>();
foreach (var chart in charts)
{
string imageTag = string.Format("<img src=cid:chart{0} /><br>", i);
htmlBody += imageTag;
