How to get the value from my picker? Xamarin forms

Question

I have trouble to get out the selected string from my picker. This is my code:

XAML:

<Picker x:Name="thePicker" >
    <Picker.Items>
        <x:String>info1</x:String>
        <x:String>info2 </x:String>
    </Picker.Items>
</Picker>

CODE:

thePicker.SelectedIndex = 1; //here is the problem i suppose, any idea what i should type?
var ourPickedItem = thePicker.Items[thePicker.SelectedIndex];

Now I only get the value "info1" even if i select number 2. It has something to do with the SelectedIndex so it only picks the "1", but I am not sure how to write the code to make it work for the selected item.

You should take a look at this:

picker.SelectedIndexChanged += (sender, args) =>
{
    if (picker.SelectedIndex == -1)
    {
        boxView.Color = Color.Default;
    }
    else
    {
        string colorName = picker.Items[picker.SelectedIndex];
        boxView.Color = nameToColor[colorName];
    }
};

Otherwise in new Xamarin Forms Release 2.3.4 exists the

Bindable Picker

you can set an ItemSource

<Picker ItemsSource="{Binding Countries}" />

and Bind the SelectedIndex property

SelectedIndex="{Binding CountriesSelectedIndex}"
