如何对Arraylist数据进行排序

Question

这是我对ArrayList数据进行排序的代码

ArrayList myList = new ArrayList();
int firstNumber=int.Parse(txt1.Text);
int secondNumber = int.Parse(txt2.Text);
for (int i = firstNumber; i <= secondNumber; i++) {
    if (i%2==0) {
        myList.Add(i);
        lstbox1.Items.Add(myList);
    }
}

但是当我运行这个程序时，就会发生这种情况：

Xaml Code

    <Grid>
            <TextBox x:Name="txt1" HorizontalAlignment="Left" Height="23" Margin="10,15,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="120"/>
            <TextBox x:Name="txt2" HorizontalAlignment="Left" Height="23" Margin="10,58,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="120"/>
            <Button x:Name="btnOk" Content="Button" HorizontalAlignment="Left" VerticalAlignment="Top" Width="75" Margin="150,15,0,0" Click="btnOk_Click"/>
            <Label x:Name="lbl1" Content="Label" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="150,55,0,0"/>
            <ListBox x:Name="lstbox1" HorizontalAlignment="Left" Height="100" VerticalAlignment="Top" Width="100" Margin="10,102,0,0"/>
        </Grid>
