请建议我一个代码发送邮件asp.net 中的脚本C#。我想建造调查表我想发送我的电子邮件 ID 上的所有信息，包括附件、主题和正文。
try
{
// Assign a sender, recipient and subject to new mail message
MailAddress sender =
new MailAddress("[email protected] /cdn-cgi/l/email-protection", "Sender");
MailAddress recipient =
new MailAddress("[email protected] /cdn-cgi/l/email-protection", "Recipient");
MailMessage m = new MailMessage(sender, recipient);
m.Subject = "Test Message";
// Define the plain text alternate view and add to message
string plainTextBody =
"You must use an email client that supports HTML messages";
AlternateView plainTextView =
AlternateView.CreateAlternateViewFromString(
plainTextBody, null, MediaTypeNames.Text.Plain);
m.AlternateViews.Add(plainTextView);
// Define the html alternate view with embedded image and
// add to message. To reference images attached as linked
// resources from your HTML message body, use "cid:contentID"
// in the <img> tag...
string htmlBody =
"<html><body><h1>Picture</h1><br>" +
"<img src=\"cid:SampleImage\"></body></html>";
AlternateView htmlView =
AlternateView.CreateAlternateViewFromString(
htmlBody, null, MediaTypeNames.Text.Html);
// ...and then define the actual LinkedResource matching the
// ContentID property as found in the image tag. In this case,
// the HTML message includes the tag
// <img src=\"cid:SampleImage\"> and the following
// LinkedResource.ContentId is set to "SampleImage"
LinkedResource sampleImage =
new LinkedResource("sample.jpg",
MediaTypeNames.Image.Jpeg);
sampleImage.ContentId = "SampleImage";
htmlView.LinkedResources.Add(sampleImage);
m.AlternateViews.Add(htmlView);
// Finally, configure smtp or alternatively use the
// system.net mailSettings
SmtpClient smtp = new SmtpClient
{
Host = "smtp.bigcompany.com",
UseDefaultCredentials = false,
Credentials =
new NetworkCredential("username", "password")
};
//<system.net>
// <mailSettings>
// <smtp deliveryMethod="Network">
// <network host="smtp.bigcompany.com"
// port="25" defaultCredentials="true"/>
// </smtp>
// </mailSettings>
//</system.net>
smtp.Send(m);
