用C#编写的读取客户端MAC地址的ActiveX控件,在IE中运行时出现权限错误,无从下手,求教
我用C#写了一个读取客户端MAC地址的控件,在WinForm下运行正常,搬到IE里就出现权限错误:请求“System.Security.Permissions.RegistryPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089”类型的权限已失败。
窗体上只有一个文本框,用来显示MAC地址,源代码如下:

--------------------编程问答-------------------- 用C#写ActiveX控件？太搞笑了吧...客户端要就是不装.NET Framework你能怎么办？ --------------------编程问答-------------------- 只要实现功能就行了,客户端没有framework,装一个就行了 --------------------编程问答-------------------- 哈哈，如果是这样你还不入直接写net装配件了
net装配件也是可以直接再html页面里用<object>标签引入的
参考http://www.sifung.com/pages/879.shtm --------------------编程问答-------------------- 其实如果是编写控件取得mac地址，也用不着这么麻烦的手段
反正你的控件要在客户端运行，那么就直接启动cmd命令的ipconfig -all命令，程序接收回显的值就成
--------------------编程问答-------------------- 事实上我们总是讨论到别的方面上.而我问的只是个权限问题.
回vrhero(我是真小人/最烦伪君子...)
如果我们需要完全考虑所有人的客户端环境, 那还是写个C/S的,放在HTML上让别人下载,这样才能解决所有问题.现在各银行网站的ActiveX在FireFox下均表现不好.
回wanghui0380(放歌)
你的这个装配件,其实我在写这些代码之前就在用. 只不过最后我稍微改了一下,编译成ActiveX而已. 我认为他仍然存在权限问题, 当然这个可以测试一下.
而用cmd去取得MAC地址,我不知道你是否真的做过, 在WinForm下去跑后台cmd命令没有问题,并不一定在ActiveX里能跑吧, 当然这个也需要验证.
不得已,只好去挖了个VB6出来,写了几千行代码,从获取MAC,到CPUID和硬盘物理ID, 写得很不爽,但也算解决问题.
还是谢谢各位 --------------------编程问答-------------------- 不错啊！写得很好啊！ --------------------编程问答-------------------- @LZ

请问一下LZ 试过没有MFC ActiveX 控件，不知怎么实现的~~
补充：.NET技术 , C#
