无法加载xxx.dll找不到指定的模块

[netajax1]

各位好，我现在用C# 调用身份证读卡器做成activx控件js端调用
提示无法加载cardapi2.dll 系统找不到指定的模块

而在winform端测试可以正常读取身份证

C#代码

 [DllImport("cardapi2.dll", EntryPoint = "OpenCardReader", CallingConvention = CallingConvention.StdCall,
            CharSet = CharSet.Unicode)]
        public static extern Int32 OpenCardReader(Int32 lPort, UInt32 ulFlag);

        [DllImport("cardapi2.dll", EntryPoint = "GetPersonMsgW",
            CallingConvention = CallingConvention.StdCall, CharSet = CharSet.Unicode)]
        public static extern Int32 GetPersonMsgW(ref PERSONINFOW pInfo, string pszImageFile);

        [DllImport("cardapi2.dll", EntryPoint = "CloseCardReader",
            CallingConvention = CallingConvention.StdCall, CharSet = CharSet.Unicode)]
        public static extern Int32 CloseCardReader();


        [DllImport("cardapi2.dll", EntryPoint = "CloseCardReader",
            CallingConvention = CallingConvention.StdCall, CharSet = CharSet.Unicode)]
        public static extern Int32 ResetCardReader();

如果是因为bs访问页面是虚拟路径原因，那我bs端怎么设置这个DllImport("xxx.dll" 这个dll路径
谢谢

你这个dll文件要放在客户端才能读身份证信息 cardapi2.dll是api形式的dll，不能在前台通过CreateObject方式创建对象的 需要做成com型的能用regsvr32注册的方式才行
