public static void createmessagewithattachment（string server)

console.writeline（ "inline {0} ", cd.inline);
console.writeline（ "parameters: {0} ", cd.parameters.count);
foreach （dictionaryentry d in cd.parameters)

}
这以上的代码是vs2005给出的发邮件附件的实例。
通过该实例，可以顺利的发邮件附件了，不过，这也只是可以发单个附件的。
我现在提问的是，在一封邮件中什么可以同时发多个附件？
