使用C＃按顺序获取Windows右键单击项目 [英] Get windows right click items in order using C#

问题描述

我想按顺序返回窗口右键单击HKEY_CLASSES_ROOT中的项目。通过顺序，例如当您单击文件夹或某个扩展名时，您获得了不同的菜单，并且它们位于HKEY_CLASSES_ROOT的不同位置，当Windows处于不同的位置时，Windows如何知道按顺序返回它们？我怎么可能？在我的小项目中使用vs c＃，我也找不到所有的菜单项。



PS：我还年轻爱好程序员，我不太了解win shell / script，如果你能简单解释或链接一个关于这个的话题会很好。



我尝试了什么：



谷歌搜索没有帮助。

无法找到所有菜单项只有这两个：



HKEY_CLASSES_ROOT\Folder\shell

HKEY_CLASSES_ROOT \Directory\shell

I want to return the windows right click items that is in HKEY_CLASSES_ROOT in order. By order like when you click a folder or a certain extension you get different menus and they are in separate places in HKEY_CLASSES_ROOT, how does windows know to return them in order on right click when they are in separate places? and so how could I?, using vs c# in my small project, also I can't find all of the menu items.

P.S: I'm a young hobby programmer and I don't know much about win shell/script, it would be nice if you could explain briefly or link a topic about this.

What I have tried:

Googling didn't help.
Cant find all the menu items got only these 2:

HKEY_CLASSES_ROOT\Folder\shell
HKEY_CLASSES_ROOT\Directory\shell

推荐答案

如果您对此主题一无所知，那么我建议从一个更简单的项目开始。您可以在 https://www.codeproject.com/KB/shell/ 中找到许多有用的教程[< a href =https://www.codeproject.com/KB/shell/target =_ blanktitle =New Window> ^ ]部分，或者使用Google。

If you do not know anything about this subject then I would suggest starting with a simpler project. You can find lots of useful tutorials in the https://www.codeproject.com/KB/shell/[^] section, or by using Google.

这里有一个很好的示例，说明如何遍历注册表的所有密钥： https ：//stackoverflow.com/questions/1458653/iterate-through-registry-entries

在此处阅读注册表项类： https://docs.microsoft.com/en-us/dotnet/api/microsoft.win32.registrykey？ view = netframework-4.7.2



有多个键处理右键单击上下文菜单。

For文件：

HKEY_CLASSES_ROOT \ * \ shellex \ContextMenuHandlers \

S程序的其他菜单项存储在以下位置：

HKEY_CLASSES_ROOT \ * \ shell

HKEY_CLASSES_ROOT \ AllFileSystemObjects\ShellEx\ContextMenuHandlers



对于文件夹项目：

HKEY_CLASSES_ROOT \Folder\shellex\ContextMenuHandlers \

HKEY_CLASSES_ROOT \Directory \ shell



对于桌面商品：

HKEY_CLASSES_ROOT \Directory \ Background\shell

HKEY_CLASSES_ROOT \Directory \ Background\shellex \ContextMenuHandlers





获取密钥并遍历所有子密钥是一件简单的事。

There is a good example of how to loop through all the keys for a registry here: https://stackoverflow.com/questions/1458653/iterate-through-registry-entries
Read about the Registry Key Class here: https://docs.microsoft.com/en-us/dotnet/api/microsoft.win32.registrykey?view=netframework-4.7.2

There are multiple keys that deal with the right-click context menu.
For file items:
HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers\
Some additional menu items for programs are stored at these locations:
HKEY_CLASSES_ROOT\*\shell
HKEY_CLASSES_ROOT\AllFileSystemObjects\ShellEx\ContextMenuHandlers

For folder items:
HKEY_CLASSES_ROOT\Folder\shellex\ContextMenuHandlers\
HKEY_CLASSES_ROOT\Directory\shell

For desktop items:
HKEY_CLASSES_ROOT\Directory\Background\shell
HKEY_CLASSES_ROOT\Directory\Background\shellex\ContextMenuHandlers


It is a simple thing to get a key and loop over all the subkeys.

using Microsoft.Win32;

        public void EnumerateRegistryKeys()
        {
            RegistryKey key = Registry.<desired root here>.OpenSubKey("<desired key here>");
            foreach (string subKeyName in key.GetSubKeyNames())
            {
                //Do something with subKeyName
            }
        }

在上面的代码中，您必须将所需的根和键替换为角度文本括号。例如：

In the above code you must substitute your desired root and key for the text in angle brackets. For example:

RegistryKey key = Registry.ClassesRoot.OpenSubKey(@"Folder\shellex\ContextMenuHandlers\");

注意：读取注册表非常安全，但将值写入注册表可能会导致严重问题。在更改之前备份注册表。

NOTE: Reading the registry is pretty safe, but writing values to the registry can cause serious problems. Backup the registry before changing it.
