❔ Item.Is a Number

Hey, I have this list:

        { "+", "-", "*", "/", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9" };

        { "+", "-", "*", "/", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9" };

I iterate through the list with a foreach. I want to check if the item is a number or not. So is there something like

foreach
   if((int)item.Is a number)
      .....

foreach
   if((int)item.Is a number)
      .....

Hey, I want to set the label on a random position. After this I want to edit the content of the label, buy how can I do that if my label are object or UIElement

foreach (var OR UIElement label in RememberScreen.Children)
                if (typeof(Label).IsInstanceOfType(label))
                {
                    while (true)
                    {
                        // increment i
                        i++;
                        // set position from left
                        posL ......
                        // set position from top
                        posT = .....
                        Debug.WriteLine(posL + " " + posT);

                        if (oldPosT.Contains(posT) != true)
                        {
                            label.Content = $"{i}"; // HERE IS THE ERROR
                            Canvas.SetLeft(labels[i], posL);
                            Canvas.SetTop(labels[i], posT);
                            label.Visibility = Visibility.Visible;
                            // add the position to the list
                            oldPosT.Add(posT);
                            Debug.WriteLine(oldPosT[i]);
                            break;
                        }

foreach (var OR UIElement label in RememberScreen.Children)
                if (typeof(Label).IsInstanceOfType(label))
                {
                    while (true)
                    {
                        // increment i
                        i++;
                        // set position from left
                        posL ......
                        // set position from top
                        posT = .....
                        Debug.WriteLine(posL + " " + posT);

                        if (oldPosT.Contains(posT) != true)
                        {
                            label.Content = $"{i}"; // HERE IS THE ERROR
                            Canvas.SetLeft(labels[i], posL);
                            Canvas.SetTop(labels[i], posT);
                            label.Visibility = Visibility.Visible;
                            // add the position to the list
                            oldPosT.Add(posT);
                            Debug.WriteLine(oldPosT[i]);
                            break;
                        }

Can I replace the label from my canvas with a new label than it's exactly the same with different content?
