C# WPF Buttons which have same event but they have different Tag as output [duplicate]

Question

Hello I have a question. I need to know how i can put one event for many buttons. Where every button will make labelfloor different text value(1-4 fro example)

   using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace WpfApp1
{
    /// <summary>
    /// Interakční logika pro MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            bool Aktive;
            bool lights;
            int actualyfloor;
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {

            labelFloor.Content = button(1-4).Tag.ToString(); // When i click at 1-4 button its will change value in labelFloor to (1-4)
        }
    }

The button that was clicked should be given to you in the parameter sender. Check that it is of type Button and then read the Tag property from it.

private void Button_Click(object sender, RoutedEventArgs e)
{
    Button button = sender as Button;
    if (button == null) return;

    labelFloor.Content = button.Tag.ToString();
}
