我有picturebox1，想将picturebox1中显示的图片添加到我的电子邮件正文中
【问题讨论】：
您在哪里将图像加载到您的应用程序中？ 图片是我在文本框中输入的内容生成的二维码，然后它将显示在图片框中 Send inline image in email的可能重复 【参考方案1】：您需要将其添加为电子邮件的嵌入式资源并为其创建 html 视图，这是一个入门示例：
private static void AddImageToEmail(MailMessage mail, Image image)
var imageStream = GetImageStream(image);
var imageResource = new LinkedResource(imageStream, "image/png") ContentId = "added-image-id" ;
var alternateView = AlternateView.CreateAlternateViewFromString(mail.Body, mail.BodyEncoding, MediaTypeNames.Text.Html);
alternateView.LinkedResources.Add(imageResource);
mail.AlternateViews.Add(alternateView);
private static Stream GetImageStream(Image image)
// Conver the image to a memory stream and return.
var imageConverter = new ImageConverter();
var imgaBytes = (byte[])imageConverter.ConvertTo(image, typeof(byte[]));
var memoryStream = new MemoryStream(imgaBytes);
return memoryStream;

【参考方案2】：您需要调整代码以包含内嵌图像。
请参阅以下已回答此问题的问题：

代码 sn-p（您需要添加类似的内容才能获得相同的结果），取自链接 1；
protected void Page_Load(object sender, EventArgs e)
string Themessage = @"<html>
<body>
<table 100%"">
<tr>
<td style=""font-style:arial; color:maroon; font-weight:bold"">
Hi! <br>
<img src=cid:myImageID>
</td>
</tr>
</table>
</body>
</html>";
sendHtmlEmail("from@gmail.com", "tomailaccount", Themessage, "Scoutfoto", "Test HTML Email", "smtp.gmail.com", 25);
protected void sendHtmlEmail(string from_Email, string to_Email, string body, string from_Name, string Subject, string SMTP_IP, Int32 SMTP_Server_Port)
//create an instance of new mail message
MailMessage mail = new MailMessage();
//set the HTML format to true
mail.IsBodyHtml = true;
//create Alrternative HTML view
AlternateView htmlView = AlternateView.CreateAlternateViewFromString(body, null, "text/html");
//Add Image
LinkedResource theEmailImage = new LinkedResource("E:\\IMG_3332.jpg");
theEmailImage.ContentId = "myImageID";
//Add the Image to the Alternate view
htmlView.LinkedResources.Add(theEmailImage);
//Add view to the Email Message
mail.AlternateViews.Add(htmlView);
//set the "from email" address and specify a friendly 'from' name
mail.From = new MailAddress(from_Email, from_Name);
//set the "to" email address
mail.To.Add(to_Email);
//set the Email subject
mail.Subject = Subject;
//set the SMTP info
System.Net.NetworkCredential cred = new System.Net.NetworkCredential("fromEmail@gmail.com", "fromEmail password");
SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);
smtp.EnableSsl = true;
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.UseDefaultCredentials = false;
smtp.Credentials = cred;
//send the email
smtp.Send(mail);
