How to use objects (like entry) in Xamarin.form in private void?

Issue

I want to use the button to add entry text to the editor but I get an error! Here is my code:

public MainPage()
        {
            InitializeComponent();
            var InputOrdersEntry = new Entry
            {
                FontSize = 10,
                Placeholder = "Enter Your order",
                PlaceholderColor = Color.Gray,
                TextColor = Color.White,
                BackgroundColor = Color.DarkGray,
                MaxLength = 1000,
                Keyboard = Keyboard.Text,
                IsSpellCheckEnabled = false,
                IsTextPredictionEnabled = false
            };
            Button EnterTextToEditorButton = new Button
            {
                FontSize = 10,
                Text = "Enter",
            };
            var LogsEditor = new Editor
            {
                FontSize = 10,
                TextColor = Color.White,
                BackgroundColor = Color.DarkGray,
                MaxLength = 100000,
                IsSpellCheckEnabled = false,
                IsTextPredictionEnabled = false,
                IsReadOnly = true,
            };
        }
        private void EnterTextToEditorButton (object sender, EventArgs e)
        {
            LogsEditor.Text += InputOrdersEntry.Text;
        }

And this is Errors: Error CS0103 The name 'LogsEditor' does not exist in the current context Error CS0103 The name 'InputOrdersEntry' does not exist in the current context

What should I do to fix this errors and do my job too?

Solution

You should declare the LogsEditor/InputOrdersEntry at the class level so that they can be accessed in whole class. If you declared them in one method, it can only be accessed in that method:

The complete code here:

public partial class MainPage : ContentPage
{
    //declaring here as a class level variable
    public Editor LogsEditor;
    public Entry InputOrdersEntry;

    public MainPage()
    {
        InitializeComponent();

        InputOrdersEntry = new Entry
        {
            FontSize = 10,
            Placeholder = "Enter Your order",
            PlaceholderColor = Color.Gray,
            TextColor = Color.White,
            BackgroundColor = Color.DarkGray,
            MaxLength = 1000,
            Keyboard = Keyboard.Text,
            IsSpellCheckEnabled = false,
            IsTextPredictionEnabled = false
        };
        Button EnterTextToEditorButton = new Button
        {
            FontSize = 10,
            Text = "Enter",
        };
        LogsEditor = new Editor
        {
            FontSize = 10,
            TextColor = Color.White,
            BackgroundColor = Color.DarkGray,
            MaxLength = 100000,
            IsSpellCheckEnabled = false,
            IsTextPredictionEnabled = false,
            IsReadOnly = true,
        };
    }
    private void EnterTextToEditorButton(object sender, EventArgs e)
    {
        LogsEditor.Text += InputOrdersEntry.Text;
    }
}
