WPF中设置快捷键

标签：

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)
            {
            }

        }
