我正在使用此答案中的以下代码通过 Gmail 在 .NET 中发送电子邮件。我遇到的问题是在电子邮件中添加附件。如何使用下面的代码添加附件?
using System.Net.Mail;
var fromAddress = new MailAddress("[email protected]", "From Name");
var toAddress = new MailAddress("[email protected]", "To Name");
const string fromPassword = "fromPassword";
const string subject = "Subject";
const string body = "Body";
var smtp = new SmtpClient
{
Host = "smtp.gmail.com",
Port = 587,
EnableSsl = true,
DeliveryMethod = SmtpDeliveryMethod.Network,
UseDefaultCredentials = false,
Credentials = new NetworkCredential(fromAddress.Address, fromPassword)
};
using (var message = new MailMessage(fromAddress, toAddress)
{
Subject = subject,
Body = body
})
{
smtp.Send(message);
}
从
message
方法调用创建的 new MailMessage
对象具有属性 .Attachments
。
例如:
message.Attachments.Add(new Attachment(PathToAttachment));
按照 MSDN 中的建议使用 Attachment 类:
// Create the file attachment for this e-mail message.
Attachment data = new Attachment(file, MediaTypeNames.Application.Octet);
// Add time stamp information for the file.
ContentDisposition disposition = data.ContentDisposition;
disposition.CreationDate = System.IO.File.GetCreationTime(file);
disposition.ModificationDate = System.IO.File.GetLastWriteTime(file);
disposition.ReadDate = System.IO.File.GetLastAccessTime(file);
// Add the file attachment to this e-mail message.
message.Attachments.Add(data);
像这样更正你的代码
System.Net.Mail.Attachment attachment;
attachment = new System.Net.Mail.Attachment("your attachment file");
mail.Attachments.Add(attachment);

希望这对你有帮助。

提示:如果之后添加附件,邮件正文会被附件文件路径覆盖,所以先附加,后添加正文
mail.Attachments.Add(new Attachment(file));
mail.Body = "body";
一行答案:
mail.Attachments.Add(new System.Net.Mail.Attachment("pathToAttachment"));
