Write random text into Textbox

Question

I'm creating n 8th ball and I'm trying to randomly generate one of the eight phrases into a textbox once a button is tapped and can't get my head around how to get my phrases in a textbox when a button is tapped.

private void Button1_Tapped(object sender, TappedRoutedEventArgs e)
    {
        Random num = new Random();
        int a = num.Next(9);

        switch (a)
        {
            case 0:
               Console.;
                break;
            case 1:
                Console.WriteLine.TextBox("Yes");
                break;
            case 2:
                Console.WriteLine.TextBox("No");
                break;
            case 3:
                Console.WriteLine.TextBox("Maybe");
                break;
            case 4:
                Console.WriteLine.TextBox("You could say that");
                break;
            case 5:
                Console.WriteLine.TextBox("Most certain");
                break;
            case 6:
                Console.WriteLine.TextBox("Dont even try");
                break;
            case 7:
                Console.WriteLine.TextBox("Full steam ahead");
                break;
        }
    }

Console.WriteLine() normally writes to the Console output in a Console App. So it seems you are mixing something up...

Your textbox in the wpf app needs to have a variable name e.g. theTextBox and then you assign the string to the .Text property.

private void Button1_Tapped(object sender, TappedRoutedEventArgs e)
{
    Random num = new Random();
    int a = num.Next(9);

    switch (a)
    {
        case 0:
            theTextBox.Text = "";
            break;
        case 1:
            theTextBox.Text = "Yes";
            break;
        case 2:
            theTextBox.Text = "No";
            break;
        case 3:
            theTextBox.Text = "Maybe";
            break;
        case 4:
            theTextBox.Text = "You could say that";
            break;
        case 5:
            theTextBox.Text = "Most certain";
            break;
        case 6:
            theTextBox.Text = "Dont even try";
            break;
        case 7:
            theTextBox.Text = "Full steam ahead";
            break;
    }
}
