通过电子邮件将图像作为嵌入图像发送到正文中时出现问题.图像文件显示为附件,但是内嵌图像部分显示为红色x.

这是我到目前为止所拥有的

LinkedResource inline = new LinkedResource(filePath);
inline.ContentId = Guid.NewGuid().ToString();
MailMessage mail = new MailMessage();
Attachment att = new Attachment(filePath);
att.ContentDisposition.Inline = true;
mail.From = from_email;
mail.To.Add(data.email);
mail.Subject = "Client: " + data.client_id + " Has Sent You A Screenshot";
mail.Body = String.Format(
    "<h3>Client: " + data.client_id + " Has Sent You A Screenshot</h3>" +
    @"<img src=""cid:{0}"" />", inline.ContentId);

mail.IsBodyHtml = true;
mail.Attachments.Add(att);

如何在身体内容中附加图像.我写了下面的代码

System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
string UserName = "xyz@someorg.com";
string Password = "my password";
message.To.Add(new System.Net.Mail.MailAddress("toaddress@toadddress.com"));
message.From = new  System.Net.Mail.MailAddress("fromaddress@fromaddress.com");              
message.Subject = "test subject";
message.Body = "<img src=@'C:\\Sunset.jpg'/>";                
message.IsBodyHtml = true;
System.Net.Mail.SmtpClient smtpClient = new System.Net.Mail.SmtpClient();
 smtpClient.Host = "hostname";
 smtpClient.Port = 25;
 smtpClient.Credentials = new System.Net.NetworkCredential(UserName, Password);
 smtpClient.Send(message);

代码很好,因为我也收到了消息,但图像在身体内部[X]而不是图像.怎么解决这个？路径是正确的？
