跳棋 c# 每个玩家都玩一次不可能

Question

I created a WPF app to play checkers. While lauching, a bunch of white and black buttons are created(15 each). The white buttons are called btnWhite and the black btnBlack.

I'd like that, if I play with the whites, then the next button to be clicked can't be a white one. So we have white play, next black, next white...

I really don't know how to manage this, because as I have coded, white can play as many times as they want, so as the black..

Would be really appreciated if you guys could help me !

Here's how I create the buttons :

for (int i = 0; i < 10; i++)
        {
            for (int j = 0; j < 4; j++)
            {
                if ((i + j) % 2 != 0)
                {
                    Image img = new Image();
                    img.BeginInit();
                    img.Source = new BitmapImage(new Uri(@"./ressources/pionNoir.png", UriKind.Relative));



                    img.EndInit();

                    StackPanel stackPnl = new StackPanel();
                    stackPnl.Orientation = Orientation.Horizontal;
                    stackPnl.Margin = new Thickness(1);
                    stackPnl.Children.Add(img);

                    Button btnBlack = new Button();
                    btnBlack.Content = stackPnl;
                    btnBlack.Name = "Black";
                    btnBlack.Tag = "Black";
                    btnBlack.Click += Pawn_Click;
                    _grid.Children.Add(btnBlack);
                    Grid.SetRow(btnBlack, j);
                    Grid.SetColumn(btnBlack, i);
                    tab[i, j].initSide(false);
                }
            }
        }

Pawn_Click :

 public void Pawn_Click(object sender, RoutedEventArgs e)
    {
        Button b = sender as Button;
        if (t)
        {
            selectedPawn = b;
            t = false;
        }

        if (b.BorderBrush == Brushes.SteelBlue)
        {
            b.BorderThickness = new Thickness(1);
            b.BorderBrush = Brushes.Black;

        }
        else
        {
            b.BorderBrush = Brushes.SteelBlue;
            b.BorderThickness = new Thickness(3);

        }
        if (b != selectedPawn)
        {
            selectedPawn.BorderThickness = new Thickness(1);
            selectedPawn.BorderBrush = Brushes.Black;
        }
        selectedPawn = b;

        pawnPosition[0] = Grid.GetColumn(selectedPawn);
        pawnPosition[1] = Grid.GetRow(selectedPawn);

        isDraught = false;
        if (selectedPawn.Tag.ToString() == "White")
        {
            whoPlays = true;
        }
        else
        {
            whoPlays = false;
        }
        if (selectedPawn.Name.Contains("Draught"))
        {
            b.BorderBrush = Brushes.Red;
            b.BorderThickness = new Thickness(3);
            isDraught = true;
        }

@UPDATE I've tried this inside my Pawn_Click method :

    if(b.Name=="Black")
        {
            selectedPawn.IsEnabled = true;
        }
     else if(b.Name=="White")
        {
            selectedPawn.IsEnabled = false; ;
        }

So, I created a new method to get all the buttons grom the grid, as @Rup said and retrieved the tag of the buttons, so I could disable all buttons from one color and let the other color button's enabled :

 public void desactivate_Btn()
    {
        UIElement b;
        for (int i = 0; i < theGrid.Children.Count; i++)
        {
            b = theGrid.Children[i];
            if (whoPlays)
            {
                if (((Button)b).Tag.ToString() == "White")
                {

                    b.IsEnabled = false; // to disable all the buttons
                   selectedPawn = null; // to disable the selected button
                   t = true; // i had to put 't' true as this variable needs to be true at the beginning of my code


                }
                else if (((Button)b).Tag.ToString() == "Black")
                {
                    b.IsEnabled = true;
                }
            }
            else
            {
                if (((Button)b).Tag.ToString() == "Black")
                {
                    b.IsEnabled = false;
                   selectedPawn = null;
                    t = true;
                }
                else if (((Button)b).Tag.ToString() == "White")
                {
                    b.IsEnabled = true;

                }
            }
        }
    }

Thank you for your help, really appreciated !
