C# WPF Using List

標題：C# WPF使用List功能
C# (MainWindow.xaml.cs)：

using System;
using System.Windows;

namespace WPFVectorList
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        public System.Collections.Generic.List<int> arr = new System.Collections.Generic.List<int>();

        private void btn_show_Click(object sender, RoutedEventArgs e)
        {
            tbk.Text = "";
            foreach (int i in arr)
            {
                tbk.Text += i + "\n";
            }
        }

        private void btn_add_Click(object sender, RoutedEventArgs e)
        {
            arr.Add(Int32.Parse(tbx.Text));
        }
    }
}

WPF (MainWindow.xaml)：

<Window x:Class="WPFVectorList.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <TextBlock Margin="12,12,12,65" Name="tbk" />
        <Button Content="ADD" Height="40" HorizontalAlignment="Left" Margin="118,259,0,0" Name="btn_add" VerticalAlignment="Top" Width="100" Click="btn_add_Click" />
        <Button Content="Show" Height="40" HorizontalAlignment="Left" Margin="224,0,0,12" Name="btn_show" VerticalAlignment="Bottom" Width="100" Click="btn_show_Click" />
        <TextBox Height="40" HorizontalAlignment="Left" Margin="12,0,0,12" Name="tbx" VerticalAlignment="Bottom" Width="100" Text="1" />
    </Grid>
</Window>

說明：
在C# WPF使用System.Collections.Generic的List實現在陣列Push新值的功能。
