目前在开发标题中的组件，在组件中需要调用第三方C++版本的DLL库，该库用于视频设备的操控，并且该组件运行在JSP页面中，DLL库中需要相关的Struct的封装，下面将列出：

        [StructLayoutAttribute(LayoutKind.Explicit)]
        public struct WIFI_AUTH_PARAM
        {
            [FieldOffsetAttribute(0)]
            public UNION_EAP_TTLS EAP_TTLS;

            [FieldOffsetAttribute(0)]
            public UNION_EAP_PEAP EAP_PEAP;

            [FieldOffsetAttribute(0)]
            public UNION_EAP_TLS EAP_TLS;
        }

结构体中第一个Struct我将进行说明：

[StructLayoutAttribute(LayoutKind.Sequential, CharSet = CharSet.Ansi, Size = 144)]
        public struct UNION_EAP_TTLS
        {
            public byte byEapolVersion;
            public byte byAuthType;
            [MarshalAsAttribute(UnmanagedType.ByValArray, SizeConst = 2, ArraySubType = UnmanagedType.I1)]
            public byte[] byRes1;
            [MarshalAsAttribute(UnmanagedType.ByValArray, SizeConst = NAME_LEN, ArraySubType = UnmanagedType.I1)]
            public byte[] byAnonyIdentity;
            [MarshalAsAttribute(UnmanagedType.ByValArray, SizeConst = NAME_LEN, ArraySubType = UnmanagedType.I1)]
            public byte[] byUserName;
            [MarshalAsAttribute(UnmanagedType.ByValArray, SizeConst = NAME_LEN, ArraySubType = UnmanagedType.I1)]
            public byte[] byPassword;
            [MarshalAsAttribute(UnmanagedType.ByValArray, SizeConst = 44, ArraySubType = UnmanagedType.I1)]
            public byte[] byRes;
        }

但是在运行时遇到错误：Error    13    Cannot register assembly "D:\Code\NET\Casic.ActiveX\Casic.ActiveX\bin\Debug\Casic.ActiveX.dll". Could not load type 'WIFI_AUTH_PARAM' from assembly 'Casic.ActiveX, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' because it contains an object field at offset 0 that is incorrectly aligned or overlapped by a non-object field.

如果去掉项目-》属性 -》Build (Register for COM interop)选项，则编译顺利通过，请各位帮帮忙，谢谢大家！
