第一步：创建C#类库项目，修改“名称”为HuaYun.ActiveX
第二步：修改AssemblyInfo.cs，增加代码
//自定添加 [assembly: AllowPartiallyTrustedCallers()]
第三步：右键工程，“添加”-“用户控件”命名为“ActiveXControl.cs”
第四步：按照第三步的方法添加接口IObjectSafety.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
namespace HuaYun.ActiveX
{
[ComImport, GuidAttribute("CB5BDC81-93C1-11CF-8F20-00805F2CD064")]
[InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)]
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);
}
}
第五步：添加调用JS的接口IOleClientSite.cs，IOleContainer.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
namespace HuaYun.ActiveX
{
[ComImport,Guid("00000118-0000-0000-C000-000000000046"),InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
interface IOleClientSite
{
void SaveObject();
void GetMoniker(uint dwAssign, uint dwWhichMoniker, object ppmk);
void GetContainer(out IOleContainer ppContainer);
void ShowObject();
void OnShowWindow(bool fShow);
void RequestNewObjectLayout();
}
}
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
namespace HuaYun.ActiveX
{
[ComImport,Guid("0000011B-0000-0000-C000-000000000046"),InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)]
interface IOleContainer
{
void EnumObjects([In, MarshalAs(UnmanagedType.U4)] int grfFlags,
[Out, MarshalAs(UnmanagedType.LPArray)] object[] ppenum);
void ParseDisplayName([In, MarshalAs(UnmanagedType.Interface)] object pbc,
[In, MarshalAs(UnmanagedType.BStr)] string pszDisplayName,
[Out, MarshalAs(UnmanagedType.LPArray)] int[] pchEaten,
[Out, MarshalAs(UnmanagedType.LPArray)] object[] ppmkOut);
void LockContainer([In, MarshalAs(UnmanagedType.I4)] int fLock);
}
}
第六步：编写ActiveXControl.cs代码，类上的GUID很关键这个就是“Object”的“classid”
ps：<object classid="clsid:de4479a4-af99-45b0-b0ce-d72bd4c2c37d" ></object>

ps：以上完成了编码工作，现在要生成项目，我使用的是VS2017没有安装部署工具需要在“工具”-“扩展和更新”找到“Mircrosoft Visual Studio 2017 Installer Projects”下载安装。
补充步骤：右键工程属性，“应用程序”-“程序集信息”勾选使程序集COM可见。“生成”勾选为COM互操作注册
第七步：创建安装项目命名为“TYacticeX”，ps：右键工程顶级菜单
第八步：修改工程属性，将“RemovePreviousVers”的值设置为True
第九步：右键安装项目，“Add”-“项目输出”-“主输出”，然后输出安装文件，一个exe和一个msi
第十步：开始写对应的html代码与JS代码
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<script type="text/javascript">
function OnScaned (filename){
document.getElementById("dx").value =filename;
}
</script>
</head>
<body>
<label for="jsCall">js call ActiveX:</label>
<button id="jsCall" onclick="csharpActiveX.SayHi('hello word');">call</button>
