一、新建项目—>类库,取名:ActiveXDemo

二、右键项目属性:应用属性==>程序集信息=>使程序集Com可见,
生成==>输出==>为com互操作注册；新建接口类取名:IObjectSafety
直接复制代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.InteropServices;//引入命名空间

namespace ActiveXDemo
{
    //[Guid("08B1EA29-0A20-46BE-8EE0-16A7505A317C")]
    //[ComImport, GuidAttribute("08B1EA29-0A20-46BE-8EE0-16A7505A317C")]
    [ComImport, GuidAttribute("CB5BDC81-93C1-11CF-8F20-00805F2CD064")]
    [InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)]
    public interface IObjectSafety
    {
        [PreserveSig]
        int GetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] ref int pdwSupportedOptions, [MarshalAs(UnmanagedType.U4)] ref int pdwEnabledOptions);

        [PreserveSig()]
        int SetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] int dwOptionSetMask, [MarshalAs(UnmanagedType.U4)] int dwEnabledOptions);
    }
}

三、为控件创建GUID：工具→创建GUID，选5，点击复制

     #region IObjectSafety 接口成员实现（直接复制）
        private const string _IID_IDispatch = "{00020400-0000-0000-C000-000000000046}";
        private const string _IID_IDispatchEx = "{a6ef9860-c720-11d0-9337-00a0c90dcaa9}";
        private const string _IID_IPersistStorage = "{0000010A-0000-0000-C000-000000000046}";
        private const string _IID_IPersistStream = "{00000109-0000-0000-C000-000000000046}";
        private const string _IID_IPersistPropertyBag = "{37D84F60-42CB-11CE-8135-00AA004BB851}";
        private const int INTERFACESAFE_FOR_UNTRUSTED_CALLER = 0x00000001;
        private const int INTERFACESAFE_FOR_UNTRUSTED_DATA = 0x00000002;
        private const int S_OK = 0;
        private const int E_FAIL = unchecked((int)0x80004005);
        private const int E_NOINTERFACE = unchecked((int)0x80004002);
        private bool _fSafeForScripting = true;
        private bool _fSafeForInitializing = true;

        public int GetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] ref int pdwSupportedOptions, [MarshalAs(UnmanagedType.U4)] ref int pdwEnabledOptions)
        {
            int Rslt = E_FAIL;

            string strGUID = riid.ToString("B");
            pdwSupportedOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER | INTERFACESAFE_FOR_UNTRUSTED_DATA;
            switch (strGUID)
            {
                case _IID_IDispatch:
                case _IID_IDispatchEx:
                    Rslt = S_OK;
                    pdwEnabledOptions = 0;
                    if (_fSafeForScripting == true)
                        pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER;
                    break;
                case _IID_IPersistStorage:
                case _IID_IPersistStream:
                case _IID_IPersistPropertyBag:
                    Rslt = S_OK;
                    pdwEnabledOptions = 0;
                    if (_fSafeForInitializing == true)
                        pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_DATA;
                    break;
                default:
                    Rslt = E_NOINTERFACE;
                    break;
            }
            return Rslt;
        }

        public int SetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] int dwOptionSetMask, [MarshalAs(UnmanagedType.U4)] int dwEnabledOptions)
        {
            int Rslt = E_FAIL;
            string strGUID = riid.ToString("B");
            switch (strGUID)
            {
                case _IID_IDispatch:
                case _IID_IDispatchEx:
                    if (((dwEnabledOptions & dwOptionSetMask) == INTERFACESAFE_FOR_UNTRUSTED_CALLER) && (_fSafeForScripting == true))
                        Rslt = S_OK;
                    break;
                case _IID_IPersistStorage:
                case _IID_IPersistStream:
                case _IID_IPersistPropertyBag:
                    if (((dwEnabledOptions & dwOptionSetMask) == INTERFACESAFE_FOR_UNTRUSTED_DATA) && (_fSafeForInitializing == true))
                        Rslt = S_OK;
                    break;
                default:
                    Rslt = E_NOINTERFACE;
                    break;
            }

            return Rslt;
        }
        #endregion
    }
}

四、制作成安装文件
新建项目——其他项目类型——安装和部署——安装项目

五、右键安装项目——添加——项目输出

将我们的项目ActiveXDemo设为主输出；
主输出文件上右键——属性；将Register属性设为vsdrpCOM；

重新编译安装项目，打开安装项目所在目录，双击setup.exe文件或ActiveXDemoSetup.msi文件可以将浏览器插件安装到你的电脑；

六、使用ActiveX插件
新建一个Web项目或者一个Html文件，在需要使用浏览器插件的页面上加入以下代码：
其中classid是新建的GUID编码

<body>
    <object id="csharpActiveX" classid="clsid:08B1EA29-0A20-46BE-8EE0-16A7505A317C" width="100" height="150"></object>
    <!--<object classid="clsid:08B1EA29-0A20-46BE-8EE0-16A7505A317C" codebase="bin/setup.exe"
            width="200" height="40" id="helloBossma"></object>-->
    <form id="form1" runat="server">
        <div>
            <input type='button' onclick='csharpActiveX.Test()' value='我是按钮' />
        </div>
    </form>
</body>
<script type="text/javascript">
    var objCard = document.getElementById("csharpActiveX");

    if (objCard.object == null) {
        alert("csharpActiveX插件未安装！");
    }
    else {
        alert("已检测到csharpActiveX插件！");
    }
</script>

运行如下：
