About DATAbinding，How to Binding a temporary object's properties to a INT array[] in C#?

我的程式預計要在C#中以迴圈創造數個物件，並將他們的Text依序綁到一個全域的整數陣列中，用以顯示陣列中隨時變化的數值
如此:

My Project want to creat Buttons in C#，and Binding their Text to the Target array[] to display it's number
Like this:

int target[100]=0;

    void CreatButton()
    {

        for (int i = 1; i <= N; i++)
        {

            StackLaout_Hello.Children.Add(  TheButton(i)    );
        }
    }

以及 and

Button TheButton(int i)
{
     Button B
    {
        BindingContext=???  ///???
        text=??? ///???
    };
        B.SetBinding( Label.TextProperty , new Binding ( Source=target[i+1]  ); ///???
    return B;

}

我發現我若使用 setBinding 的方式來綁定的話，只有在執行 setBinding 這一行程式時才會更新一次目標數值，是不是我的綁訂條件出了點差錯，最好直接是定BindingContext的條件?
I Found a problem that if I use the code setBinding(QQQ,XXX) to Binding，it will be update Button'text only once when Run this Line，is my Binding code wrong somewhere?or should I set the BindingContext and Text properties Button?
