winform直接&D就OK,还是没有winform方便。

 方式1：

资源

输入快捷键与资源绑定

资源绑定调用操作

    <Window.Resources>
        <RoutedUICommand x:Key="download" Text="download"/>
    </Window.Resources>
    <Window.InputBindings>
        <KeyBinding Gesture="Alt+D" Key="D"  Command="{StaticResource download}"></KeyBinding>
    </Window.InputBindings>
    <Window.CommandBindings>
        <CommandBinding Command="{StaticResource download}" CanExecute="Button_Click"></CommandBinding>
    </Window.CommandBindings>

方式2：

写控件或者窗体的KeyDown事件 PreviewKeyDown="Window_KeyDown"

//Alt+D 
if ((e.KeyboardDevice.IsKeyDown(Key.LeftAlt) || e.KeyboardDevice.IsKeyDown(Key.RightAlt)) && e.KeyboardDevice.IsKeyDown(Key.D))
{
    if (Keyboard.FocusedElement != null && Keyboard.FocusedElement.GetType().Name == "TextBox") return;
    Button_Click(null, null);
}
