c#之使用C#在电子邮件中添加多个附件

如何使用 C# 在电子邮件中附加多个文件。

        MailMessage mail = new MailMessage(); 
        SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com"); 
 
        //get the userID, Pass 
        userID= register.userName; 
        password = register.pass; 
 
 
        string aa=txtTo.Text; 
        mail.From = new MailAddress(userID); 
        mail.To.Add(aa); 
        mail.Subject = txtsubject.Text; 
        mail.Body = txtComments.Text; 
 
        //Attach file 
        mail.Attachments.Add(new Attachment(txtAttachments.Text.ToString()));        
        SmtpServer.Port = 587; 
        SmtpServer.UseDefaultCredentials = false; 
        SmtpServer.Credentials = new System.Net.NetworkCredential(userID, password); 
        SmtpServer.EnableSsl = true; 
        SmtpServer.Send(mail); 
        MessageBox.Show("Email sent successfully"); 
        this.Cursor = Cursors.Default; 
 
        //close the page 
        Email email = new Email(); 
        email.Close(); 

此代码仅用于附加一个文件。我如何在 c# 2008 中附加多个文件？？？ 请给我解决方案。

请您参考如下方法:

... 
mail.Body = txtComments.Text; 
//Attach file 
mail.Attachments.Add(new Attachment(txtAttachments.Text.ToString())); 
mail.Attachments.Add(new Attachment(txtAttachments2.Text.ToString())); 
mail.Attachments.Add(new Attachment(txtAttachments3.Text.ToString())); 
mail.Attachments.Add(new Attachment(txtAttachments4.Text.ToString())); 
SmtpServer.Port = 587; 
...
