Picker item value insert to database(firebase) in xamarin form - firebase

Question

My problem is to insert data to firebase in xamarin form.
This is my CreateAccount.xaml
`
<Picker
Title="Select Security Question"
TextColor="Black"
HorizontalOptions="StartAndExpand"
FontSize="Medium"
WidthRequest="250"
TitleColor="Black"
x:Name="entryField_SecurityQuestion"
>
<Picker.Items
>
<x:String>
Who is your first love?
</x:String>
<x:String>
what subject you failed?
</x:String>
<x:String>
What is the name of your dog?
</x:String>
<x:String>
Who is your first kiss?
</x:String>
</Picker.Items>
</Picker>
codebehind.cs
async public void signButton_Clicked(System.Object sender, System.EventArgs e)
{
Picker picker = sender as Picker;
//this is how I manage my some ID from my front end
string firstName = entryField_Firstname.Text;
string lastName = entryField_Lastname.Text;
string contactNumber = entryField_PhoneNumber.Text;
string securityQuestion = picker.SelectedItem.ToString(); // this line is my trial and error, I tried some code but I cant insert data to database
Customer customer = new Customer();
customer.FirstName = firstName;
customer.LastName = lastName;
customer.SecurityQuestion = securityQuestion;//this one also, this is my trial and error approach
customer.ContactNumber = contactNumber;
var Savedata = await customerRepo.Save(customer);
}
`
I expect that, I can get the picker's item, and save it to database.
Any link that will be posted related to my post, will be appreciated. Thank you so much

If you want to get the Picker's SelectedItem, you need to refer to the x:Name="entryField_SecurityQuestion" of your picker not Picker picker = sender as Picker;,just as Jason said.
You can refer to the following code:
private void signButton_Clicked(object sender, EventArgs e)
{
// remove the following code
//Picker picker = sender as Picker;
string securityQuestion = entryField_SecurityQuestion.SelectedItem.ToString();
Customer customer = new Customer();
customer.FirstName = firstName;
customer.LastName = lastName;
customer.SecurityQuestion = securityQuestion;
}
