方式1：

窗体中加入资源

 <UserControl.Resources>

        <RoutedUICommand x:Key="Cut" Text="剪切" />

        <RoutedUICommand x:Key="Copy" Text="复制" />

        <RoutedUICommand x:Key="Paste" Text="粘贴" />

        <RoutedUICommand x:Key="Select" Text="全选" />

    </UserControl.Resources>

    <UserControl.InputBindings>

        <KeyBinding Gesture="Ctrl+X" Command="{StaticResource Cut}" />

        <KeyBinding Gesture="Ctrl+C" Command="{StaticResource Copy}" />

        <KeyBinding Gesture="Ctrl+V" Command="{StaticResource Paste}" />

    </UserControl.InputBindings>

    <UserControl.CommandBindings>

        <CommandBinding Command="{StaticResource Cut}" Executed="CommandBinding_Cut"></CommandBinding>

        <CommandBinding Command="{StaticResource Copy}" Executed="CommandBinding_Copy"></CommandBinding>

        <CommandBinding Command="{StaticResource Paste}" Executed="CommandBinding_Paste"></CommandBinding>

    </UserControl.CommandBindings>

 

其中：CommandBinding_Cut ，CommandBinding_Copy ，CommandBinding_Paste 是按下快捷键对用的事件操作

 private void CommandBinding_Cut(object sender, ExecutedRoutedEventArgs e)

 {

           

 }

方式2：

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

 

private void Window_KeyDown(object sender, KeyEventArgs e)

        {

            try

            {

                if (e.Key == Key.Enter)

                {

                    //搜索

                    if (Keyboard.FocusedElement != null && Keyboard.FocusedElement == SearchTxt) Search_Click(SearchBtn, e);

                    //文件或者文件夹重命名

                    if (Keyboard.FocusedElement != null && Keyboard.FocusedElement.GetType().Name == "TextBox")

                    {

                        TextBox box = Keyboard.FocusedElement as TextBox;

                        FilesModel model = box.DataContext as FilesModel;

                        if (model != null) ReName_LostFocus(box, e);

                    }

                    Keyboard.ClearFocus();

                }

                //Ctrl+C 全选

                if ((e.KeyboardDevice.IsKeyDown(Key.LeftCtrl) || e.KeyboardDevice.IsKeyDown(Key.RightCtrl)) && e.KeyboardDevice.IsKeyDown(Key.C))

                {

                    if (Keyboard.FocusedElement != null && Keyboard.FocusedElement.GetType().Name == "TextBox") return;

                    CommandBinding_Copy(null, null);

                }

                //Ctrl+X 全选

                if ((e.KeyboardDevice.IsKeyDown(Key.LeftCtrl) || e.KeyboardDevice.IsKeyDown(Key.RightCtrl)) && e.KeyboardDevice.IsKeyDown(Key.X))

                {

                    if (Keyboard.FocusedElement != null && Keyboard.FocusedElement.GetType().Name == "TextBox") return;

                    CommandBinding_Cut(null, null);

                }

                //Ctrl+V 全选

                if ((e.KeyboardDevice.IsKeyDown(Key.LeftCtrl) || e.KeyboardDevice.IsKeyDown(Key.RightCtrl)) && e.KeyboardDevice.IsKeyDown(Key.V))

                {

                    if (Keyboard.FocusedElement != null && Keyboard.FocusedElement.GetType().Name == "TextBox") return;

                    CommandBinding_Paste(null, null);

                }

                //Ctrl+A 全选

                if ((e.KeyboardDevice.IsKeyDown(Key.LeftCtrl) || e.KeyboardDevice.IsKeyDown(Key.RightCtrl)) && e.KeyboardDevice.IsKeyDown(Key.A))

                {

                    SelectAllCheck.IsChecked = true;

                    SelectAll_Click(SelectAllCheck, e);

                }

                //Shift+D 删除

                if ((e.KeyboardDevice.IsKeyDown(Key.LeftShift) || e.KeyboardDevice.IsKeyDown(Key.RightShift)) && e.KeyboardDevice.IsKeyDown(Key.Delete))

                {

                    DeleteBtn_Click(null, e);

                }

            }

            catch (Exception)

            {

            }

        }
