GlobalHotKeyCore 1.2.0

Global Hot Key Core

Provides an easy way to setup system-wide hot keys and react on their events. Works well in both, WPF and WebForms applications without any need to use Windows API. This fork added .NET Core 3.1+ support.

Installation

Th package is available through the NuGet by running the command

PM> Install-Package GlobalHotKeyCore

Usage

An example below demonstrates how to register system-wide hotkey Ctrl+Alt+F5 and handle it:

// Include required namespaces.
using System.Windows.Input;
using GlobalHotKey;

// Create the hotkey manager.
hotKeyManager = new HotKeyManager();

// Register Ctrl+Alt+F5 hotkey. Save this variable somewhere for the further unregistering.
var hotKey = hotKeyManager.Register(Key.F5, ModifierKeys.Control | ModifierKeys.Alt);

// Handle hotkey presses.
hotKeyManager.KeyPressed += HotKeyManagerPressed;

private void HotKeyManagerPressed(object sender, KeyPressedEventArgs e)
{
    if (e.HotKey.Key == Key.F5)
        MessageBox.Show("Hot key pressed!");
}

// Unregister Ctrl+Alt+F5 hotkey.
hotKeyManager.Unregister(hotKey);

// Dispose the hotkey manager.
hotKeyManager.Dispose();

HotKeyManager class registers and unregisters system-wide hotkeys, handles them, and raises an event on hotkeys pressing. KeyPressedEventArgs class contains information about pressed hotkey and keys modifiers. Note, that it is not necessary to unregister all hotkeys manually before closing application, because Dispose() does it. Make sure that it is called.
