C# WPF Gui Checkbox Name as array

I created with WPF some CheckBoxex. Its important for my program that i can access my Checkboxes with an array.

eg.

iGPIO[1].IsChecked

 <ScrollViewer>
            <StackPanel Margin="0,0,10,0">
                <CheckBox Name="iGPIO[0]" Content="GPIO 1"></CheckBox>
                <CheckBox Name="iGPIO[1]" Content="GPIO 2"/>
                <CheckBox Content="GPIO 3"/>
                <CheckBox Content="GPIO 4"/>
                <CheckBox Content="GPIO 5"/>
                <CheckBox Content="GPIO 6"/>
                <CheckBox Content="GPIO 7"/>
                <CheckBox Content="GPIO 8"/>
                <CheckBox Content="GPIO 9"/>
                <CheckBox Content="GPIO 10"/>
