Question 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);
}

具体实施：

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,...

在代码的某个地方创建一组受支持的邮件服务

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。
