如何在Windows(8.1)中将自定义应用程序注册为Web浏览器?

我正在尝试注册我自己的应用程序,以便它显示在列表中,以便使用我找到的信息在Windows中选择默认浏览器 around the internet 。代码运行时没有问题,似乎创建了正确的注册表项,但我的应用程序在Windows 8.1的浏览器选择选项中没有显示。

我还没有设置 UserChoice 在一些在线代码示例中显示的值,因为看起来它实际上设置了默认浏览器(只有一个值),我不想这么做,只将其注册为选项。

相关代码在RegisterBrowser中,但为了方便起见,我已经包含了完整的类。

using System;
using System.Reflection;
using Microsoft.Win32;

namespace MyApp
{
    class Program
    {
        const string AppID = "MyApp";
        const string AppName = "My App";
        const string AppDescription = "My App";
        static string AppPath = Assembly.GetExecutingAssembly().Location;
        static string AppIcon = AppPath + ",0";
        static string AppOpenUrlCommand = AppPath + " %1";
        static string AppReinstallCommand = AppPath + " --register";

        static void Main(string[] args)
        {
            if (args == null || args.Length != 1 || !HandleArg(args[0]))
                ShowHelpInfo();
        }

        static bool HandleArg(string arg)
        {
            if (string.Equals(arg, "--register", StringComparison.OrdinalIgnoreCase))
                RegisterBrowser();
            else if (string.Equals(arg, "--unregister", StringComparison.OrdinalIgnoreCase))
                UnregisterBrowser();
            else if (arg.StartsWith("http://", StringComparison.OrdinalIgnoreCase) || arg.StartsWith("https://", StringComparison.OrdinalIgnoreCase) || arg.StartsWith("ftp://", StringComparison.OrdinalIgnoreCase))
                LaunchBrowser(arg);
            else
                return false;

            return true;
        }

        static void ShowHelpInfo()
        {
            Console.WriteLine("Usage:");
            Console.WriteLine("    MyApp.exe --register               Register as web browser");
            Console.WriteLine("    MyApp.exe --unregister             Unregister as web browser");
            Console.WriteLine("    MyApp.exe \"http://example.org/\"  Launch example.org in specified browser");
        }

        static void RegisterBrowser()
        {
            // Register application.
            var appReg = Registry.LocalMachine.CreateSubKey(string.Format("SOFTWARE\\Clients\\StartMenuInternet\\{0}", AppID));
            appReg.SetValue("", AppName);
            appReg.CreateSubKey("DefaultIcon").SetValue("", AppIcon);
            appReg.CreateSubKey("shell\\open\\command").SetValue("", AppOpenUrlCommand);

            // Install info.
            var appInstallInfo = appReg.CreateSubKey("InstallInfo");
            appInstallInfo.SetValue("IconsVisible", 1);
            appInstallInfo.SetValue("ShowIconsCommand", AppPath); // TOOD: Do I need to support this?
            appInstallInfo.SetValue("HideIconsCommand", AppPath); // TOOD: Do I need to support this?
            appInstallInfo.SetValue("ReinstallCommand", AppReinstallCommand);

            // Register capabilities.
            var capabilityReg = appReg.CreateSubKey("Capabilities");
            capabilityReg.SetValue("ApplicationName", AppName);
            capabilityReg.SetValue("ApplicationIcon", AppIcon);
            capabilityReg.SetValue("ApplicationDescription", AppDescription);

            // Set up protocols we want to handle.
            var urlAssoc = capabilityReg.CreateSubKey("URLAssociations");
            urlAssoc.SetValue("http", AppID);
            urlAssoc.SetValue("https", AppID);
            urlAssoc.SetValue("ftp", AppID);
        }

        static void UnregisterBrowser()
        {
            Registry.LocalMachine.DeleteSubKeyTree(string.Format("SOFTWARE\\Clients\\StartMenuInternet\\{0}", AppID), false);
        }

        static void LaunchBrowser(string arg)
        {
            Console.WriteLine(arg);
            Console.ReadLine();
        }
    }
