WPF自定义快捷命令

1、创建一个类

public class CustomCommandTest
{
    private static RoutedUICommand customCommand;
 
    public static RoutedUICommand CustomCommand
    {
        get { return customCommand; }
    }
 
    static CustomCommandTest()
    {
        InputGestureCollection inputGestureCollection = new InputGestureCollection();
        inputGestureCollection.Add(new KeyGesture(Key.R, ModifierKeys.Control, "Ctrl+R"));
        customCommand = new RoutedUICommand("", "CustomCommand", typeof(CustomCommandTest), inputGestureCollection);
    }
}

2、在xaml中使用该类

<Window.CommandBindings>
    <CommandBinding Command="{x:Static local:CustomCommandTest.CustomCommand}" Executed="CustomCommand_Execute"/>
Window.CommandBindings>

        -- 其中的Executed就是摁下快捷键要调用code_behind的方法
