不好意思，没有学习过“Delphi”，有劳你了！ --------------------编程问答-------------------- 自己顶一下 哪位大大帮帮忙呀 万分感谢！ --------------------编程问答-------------------- 才20分,翻译程序哪有这么廉价 --------------------编程问答-------------------- 分确实太少了...再加之上班比较忙, --------------------编程问答-------------------- 就是啊，自己玩去吧 --------------------编程问答-------------------- 可悲 一个个分奴！
不搞也就算了 何必这么多言！
--------------------编程问答-------------------- 看你什么态度！ --------------------编程问答-------------------- 不可能简简单单就转换的了的。Delphi的代码又不会跟C#的代码一一对应的。而且你里面还用到了TIdHTTP控件。最多用C#实现类似的功能罢了！
补充：.NET技术 , C#
