Programmatically generate key events in C#
Simulating key events in C# can be achieved through a variety of techniques. Here's a detailed way to use the WPF framework:
WPF Solution
To simulate a key press on a specific WPF element, such as pressing the Insert key on the currently focused element:
<code class="language-csharp">var key = Key.Insert; // 要发送的键 var target = Keyboard.FocusedElement; // 目标元素 var routedEvent = Keyboard.KeyDownEvent; // 要发送的事件 target.RaiseEvent( new KeyEventArgs( Keyboard.PrimaryDevice, PresentationSource.FromVisual(target), 0, key) { RoutedEvent = routedEvent } );</code>
This solution raises the KeyDown event directly to the target, bypassing meta-processing.
Text input simulation
To simulate a TextInput event, use the following code:
<code class="language-csharp">var text = "Hello"; var target = Keyboard.FocusedElement; var routedEvent = TextCompositionManager.TextInputEvent; target.RaiseEvent( new TextCompositionEventArgs( InputManager.Current.PrimaryKeyboardDevice, new TextComposition(InputManager.Current, target, text)) { RoutedEvent = routedEvent } );</code>
