Question

我有一个 Google 的邮件程序，如下所示，我如何将其调整为其他邮件系统？有更好的方法吗？另外，我如何更改邮件来源(发件人)的名称。非常感谢所有帮助，并在此先感谢您

 MailMessage message = new MailMessage();
        message.From = new MailAddress(MailAddresds);
        message.Subject = messagesubject;
        message.Body = messagebody;


        message.To.Add(messageto);
        SmtpClient client = new SmtpClient();

        client.Credentials = new NetworkCredential(userName, password);
        client.Host = "smtp.gmail.com";
        client.Port = 587;
        client.EnableSsl = true;
        client.Send(message);

Answer 1

举个例子:

public class MailMessage
{
   public string From{get;set;}
   public string To{get;set;}
   public string Body{get;set;}
   public string Subject{get;set;}
   ....
   //other common properties you may need
}


//interface 
public interface IMailService
{
    Send(MailMessage m);
}

具体实现:

public class GoogleMail : IMailService
{
    public Send(Message msg)
    { 
       //google mail specific code
    }
}


public class YahooMail : IMailService
{
    public Send(Message msg)
    { 
       //yahoo mail specific code
    }
}

.... Hotmail,...

在代码的某处创建支持的邮件服务的集合

var mailservices = new List<IMailService>();
mailservices.Add(new GoogleMail ());
mailservice.Add(new YahooMail ());

之后，在程序运行期间，选择适当的服务来处理用户请求。
