[导入]JMail的COM和.net选择性使用。

.net盛行一时的时候，在asp.net里发送邮件也成了个不大也不小的问题。虽然.net里自己带了发邮件的组件，但使用它的人却不知道有多少。可能我对这些了解不是很深入，但在网络上搜索的时候，发现有很多人想到了把JMail的COM组件封装在.net的组件下，用它来发送邮件。前些时候我也这样做过了，效果还不错。这样一来，不管服务器是不是安装了JMail组件，只要服务器支持asp.net就可以用它来发送邮件了。

昨天在JMail的官方网站上看到了最新的JMail的.net版本，这个组件完全是用.net开发的，与.net可以是完全无缝的结合吧。于是决定在自己的项目里使用它了。然而它在每个邮件后添加了一个版本信息，让我很郁闷。至于是不是删除这个信息到不是本质问题，问题是我想两个组件都使用，或者在不同的条件下合理的使用它们，于是我改用接口来完成这项工作了。

using System;

namespace Webb.WAVE.Controls
{
    /**//// <summary>
    /// Summary description for Webb.
    /// </summary>
    public interface IEMail:IDisposable
    {
        string ServerName{get;set;}
        string ServerLoginName{get;set;}
        string ServerLoginPassword{set;}
        string Subject{set;get;}
        string Body{set;get;}
        string HTMLBody{set;get;}
        string From{set;get;}        
        //
        void AddToAddress(string i_address);
        void AddCcAddress(string i_address);
        void SendEMail();
    }
}

实现它的类可以写两个，这样一来就可以自己选择性的使用它们了：COM类
