[更新]我正在更新此答案，以在带有 Visual Studio 2017社区的* Windows 10 x64中 使用 Internet
Explorer 11 。此答案的先前版本（对于Internet Explorer 8，在Windows 7 x64和Visual Studio
2010中）在此答案的底部。 ***
创建有效的Internet Explorer 11加载项
我使用 的Visual Studio 2017年的社区 ， C＃ ， .Net框架4.6.1 ，所以某些步骤可能是你稍有不同。
您需要以 管理员 身份 打开Visual Studio 来构建解决方案，以便构建后脚本可以注册BHO（需要注册表访问）。
首先创建一个类库。我叫我 InternetExplorerExtension 。
将这些引用添加到项目中：
- Interop.SHDocVw：“ COM”选项卡/搜索
"Microsoft Internet Controls"
- Microsoft.mshtml：“程序集”选项卡/搜索
"Microsoft.mshtml"
注意： 尽管可以在“添加引用”窗口中找到MSHTML，但仍未在我的系统中注册它。这在构建时导致错误：
找不到类型库“ MSHTML”的包装程序集
可在http://techninotes.blogspot.com/2016/08/fixing-cannot-find-wrapper-
assembly-for.html上找到此修复程序， 或者，您可以运行以下批处理脚本：
"%ProgramFiles(x86)%Microsoft Visual Studio2017CommunityCommon7ToolsVsDevCmd.bat"cd "%ProgramFiles(x86)%Microsoft Visual Studio2017CommunityCommon7IDEPublicAssemblies"regasm Microsoft.mshtml.dllgacutil /i Microsoft.mshtml.dll
创建以下文件：

- 用强力钥匙在组件上签名；
- 在“调试”选项卡中，将“ 启动外部程序” 设置为
C:Program Files (x86)Internet Exploreriexplore.exe
- 在“调试”选项卡中，将“ 命令行参数” 设置为
http://msdn.microsoft.com/en-us/library/ms976373.aspx#bho_getintouch
在“构建事件”选项卡中，将 “构建后事件”命令行设置 为：
“％ProgramFiles（x86）％ Microsoft SDKs Windows v10.0A bin NETFX 4.6.1 Tools gacutil.exe” / f / i“ $（TargetDir）$（TargetFileName）”
“％windir％ Microsoft.NET framework v4.0.30319 RegAsm.exe” /取消注册“ $（TargetDir）$（TargetFileName）”
“％windir％ Microsoft.NET framework v4.0.30319 RegAsm.exe”“ $（TargetDir）$（TargetFileName）”
注意： 即使我的计算机是x64，我也使用了非x64的路径
gacutil.exe并且可以正常工作… x64的专用路径是：
C： Program Files（x86） Microsoft SDKs Windows v10.0A bin NETFX 4.6.1 Tools **x64 ** gacutil.exe
64位IE 需要64位编译和64位注册的BHO。尽管我只能使用32位IE11进行调试，但是32位注册扩展也可以通过运行64位IE11来工作。
这个答案似乎对此有一些附加信息：https :
//stackoverflow.com/a/23004613/195417
如果需要，可以使用64位重装：
％windir％ Microsoft.NET framework **64 ** v4.0.30319 RegAsm.exe
此加载项如何工作
我没有更改加载项的行为。。。下面介绍一下IE8部分。
## IE8的先前答案
伙计…这是很多工作！我很好奇如何做到这一点，以至于我自己做了。
首先…信誉不全是我的。这是我在以下网站上发现的内容的汇总：
- CodeProject文章，如何制作BHO；
- 15秒，但它不是15秒，花了大约7个小时;
- Microsoft教程，帮助我添加了命令按钮。
- 这个social.msdn主题帮助我弄清楚该程序集必须在GAC中。
- 此MSDN博客文章包含一个完整的示例
- 许多其他网站，在发现过程中…
当然，我希望我的答案具有您要求的功能：
- DOM遍历以查找某些内容；
- 显示窗口的按钮（以我为例进行设置）
- 保留配置（我将为此使用注册表）
- 最后执行javascript。
我将逐步介绍它，以及如何在 Windows 7 x64中* 使用 Internet Explorer 8 进行 管理
…请注意，我无法在其他配置中进行测试。希望你理解=） *
创建有效的Internet Explorer 8加载项
我使用的是 Visual Studio 2010 ， C＃4 ， .Net framework 4
，因此其中一些步骤可能对您略有不同。
创建了一个类库。我叫我 InternetExplorerExtension 。
将这些引用添加到项目中：
- 互操作
- Microsoft.mshtml
注意：这些参考可能在每台计算机的不同位置。
这是我在csproj中的参考部分包含的内容：
<Reference Include="Interop.SHDocVw, Version=1.1.0.0, Culture=neutral, PublicKeyToken=90ba9c70f846762e, processorArchitecture=MSIL"> <SpecificVersion>False</SpecificVersion> <EmbedInteropTypes>True</EmbedInteropTypes> <HintPath>C:Program Files (x86)Microsoft Visual Studio 9.0Common7IDEPrivateAssembliesInterop.SHDocVw.dll</HintPath></Reference><Reference Include="Microsoft.CSharp" /><Reference Include="Microsoft.mshtml, Version=7.0.3300.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"> <EmbedInteropTypes>True</EmbedInteropTypes></Reference><Reference Include="System" /><Reference Include="System.Data" /><Reference Include="System.Drawing" /><Reference Include="System.Windows.Forms" /><Reference Include="System.Xml" />
创建文件的方式与更新IE11文件的方式相同。
IEAddon.cs
您可以取消注释IE11版本中的以下几行：
...// @Eric Stob: Thanks for this hint!// This was used to prevent this method being executed more than once in IE8... but now it seems to not work anymore.if (pDisp != this.site) return;...
互操作
与IE11版本相同。
最后是表格，我们将使用它来配置选项。在此表格中，放置a
TextBox和Ok
Button。将按钮的 DialogResult 设置为
Ok 。该代码与IE11插件相同。
在项目属性中，执行以下操作：
- 用强力钥匙在组件上签名；
- 在“调试”选项卡中，将“ 启动外部程序” 设置为
C:Program Files (x86)Internet Exploreriexplore.exe
- 在“调试”选项卡中，将“ 命令行参数” 设置为
http://msdn.microsoft.com/en-us/library/ms976373.aspx#bho_getintouch
在“构建事件”选项卡中，将 “构建后事件”命令行设置 为：

“ C： Windows Microsoft.NET framework v4.0.30319 RegAsm.exe” /取消注册“ $（TargetDir）$（TargetFileName）”
“ C： Windows Microsoft.NET framework v4.0.30319 RegAsm.exe”“ $（TargetDir）$（TargetFileName）”
注意： 由于我的计算机是x64，因此我的计算机上gacutil可执行文件的路径中有一个特定的x64，可能与您的不同。
64位IE 需要64位编译和64位注册的BHO。使用64位RegAsm.exe（通常位于C： Windows Microsoft.NET
framework64 v4.0.30319 RegAsm.exe中）
此加载项如何工作
它遍历所有DOM树，用黄色背景本身替换使用按钮配置的文本。如果单击发黄的文本，它将调用动态插入页面的javascript函数。默认单词是“浏览器”，因此它与很多单词匹配！
编辑：
更改要突出显示的字符串后，您必须单击URL框，然后按Enter键。F5将不起作用，我认为这是因为F5被视为“导航”，并且需要收听导航事件（也许）。我稍后将尝试解决。
现在，该走了。我很累。随便问问题…也许是因为我要去旅行而无法回答…三天后我会回来，但在此期间我会尽量来这里。
