Question

给定一个带命令的WPF按钮，我如何获得指定的快捷方式（例如复制 - > Ctrl + C ）

Answer 1

您可以在此处使用您要查找的命令替换 ApplicationCommands.Copy 。

foreach (KeyBinding binding in InputBindings)
{
    if (binding.Command == ApplicationCommands.Copy)
    {
        MessageBox.Show(binding.Modifiers.ToString() + " + " + binding.Key.ToString());
    }
}

Answer 2

抱歉，我认为这是您问题的实际答案：

Button b = new Button();

b.Command = ApplicationCommands.Copy;

List<string> gestures = new List<string>();

if (b.Command is RoutedCommand)
{
    RoutedCommand command =  (b.Command as RoutedCommand);

    foreach (InputGesture gesture in command.InputGestures)
    {
        if (gesture is KeyGesture)
        gestures.Add((gesture as KeyGesture).DisplayString);
    }
}

如果您想要获得的原因是将其显示在按钮内容中，您可以随时执行此操作：

<Button Command="ApplicationCommands.New" Content="{Binding RelativeSource={RelativeSource Self}, Path=Command.Text}"></Button>

按钮会显示“新建”。

Answer 3

使用KeyBinding - http://msdn.microsoft.com/en-us/library/ms752308.aspx

 <Window.InputBindings>
    <KeyBinding Key="C"
          Modifiers="Control" 
          Command="ApplicationCommands.Copy" />
 </Window.InputBindings>
