c# - 谷歌邮件类

Question

我有一个谷歌邮件程序，如下所示，我怎样才能将它用于其他邮件系统？有没有更好的方法来做到这一点？另外我如何更改邮件来自（发件人）的名称。非常感谢所有帮助，并提前感谢您

 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,...

在代码中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。

简单的例子：

using System.Web.Mail;

MailMessage objMessage = new MailMessage();
objMessage.From = "from";
objMessage.To = "to";
objMessage.Subject = "subject";
objMessage.BodyFormat = MailFormat.Text;
objMessage.Body = "body";
SmtpMail.SmtpServer = "SmtpServer";
SmtpMail.Send(objMessage);
