Windows平台Electron实现文件管理器覆盖图标与右键菜单求助

需求概述 #

• 基于Electron JS开发云同步应用，将本地数据同步至云端
• 需实现两个核心功能：
  • 为文件/文件夹添加类似Google Drive、OneDrive的状态覆盖图标（对勾/叉号）
  • 在文件管理器中为目录添加右键菜单，支持添加/移除同步资产

已尝试的解决方案及问题 #

1. npm包尝试 #

测试过多个npm包实现覆盖图标和右键菜单功能，均未达到预期效果。

2. winreg修改注册表 #

使用winreg@1.2.4包修改注册表来实现覆盖图标，未成功。

3. 创建desktop.ini文件 #

通过代码生成desktop.ini文件，无效，代码如下：

fs.writeFileSync(desktopIconPath,
                `[ViewState]
                Mode=
                FolderType=Pictures
                Vid=
                
                [.ShellClassInfo]
                IconResource=${desktopicon}
                IconIndex=103
                  `);

4. C# DLL + edge-js调用（System.Runtime加载失败） #

创建C# DLL后，尝试用edge-js@19.3.0在Node.js中调用，出现无法加载System.Runtime的错误：

{ Error: Could not load file or assembly 'System.Runtime, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

edge-js调用代码

try {
    var helloDll = require('edge-js').func({
      assemblyFile: "src/ClassLibrary1.dll",
      typeName: "ClassLibrary1.test",
      methodName: "Add"
    });
    console.log(helloDll);
  } catch (error) {
    console.log(error)
  }
