如何在其他類中使用CalculationWindow而不是MainWindow？

我正在寫簡單的WPF計算器應用程序，現在我已經實現了一些基本功能，如添加，減法等。我已經意識到我的代碼看起來很糟糕，一個類可以承擔一切。我努力將每個按鈕點擊事件方法中的一些代碼提取到其他類和方法，但沒有任何結果。我知道固體原理，但作爲初學者，我在執行它們時遇到了一些困難，特別是單一可重複性原則。 CalculationWindow是TextBox的名稱。我會很感激，如果你能告訴我如何將CalculationWindow.Text = CalculationWindow.Text + "8"提取給其他班級。如何在其他類中使用CalculationWindow而不是MainWindow？

一些方法，

namespace CalculatorApplication 
{ 
    public partial class MainWindow : Window 
    { 
     private double inputFirstDigit; 
     public string actionOperator;` 

     public MainWindow() 
     { 
      InitializeComponent(); 
     } 

     private void NumberOneButton_Click(object sender, RoutedEventArgs e) 
     { 
      CalculationWindow.Text = CalculationWindow.Text + "1"; 
     } 

     private void NumberTwoButton_Click(object sender, RoutedEventArgs e) 
     { 
      CalculationWindow.Text = CalculationWindow.Text + "2"; 
     } 

     private void NumberThreeButton_Click(object sender, RoutedEventArgs e) 
     { 
      CalculationWindow.Text = CalculationWindow.Text + "3"; 
     } 

     private void NumberFourButton_Click(object sender, RoutedEventArgs e) 
     { 
      CalculationWindow.Text = CalculationWindow.Text + "4"; 
     } 

     private void NumberFiveButton_Click(object sender, RoutedEventArgs e) 
     { 
      CalculationWindow.Text = CalculationWindow.Text + "5"; 
     } 

     private void NumberSixButton_Click(object sender, RoutedEventArgs e) 
     { 
      CalculationWindow.Text = CalculationWindow.Text + "6"; 
     } 

     private void NumberSevenButton_Click(object sender, RoutedEventArgs e) 
     { 
      CalculationWindow.Text = CalculationWindow.Text + "7"; 
     }

可以作爲依賴於主窗口的構造函數（其他類注射），如：

private OtherClass otherClass; 
public MainWindow(OtherClass otherClass) 
    { 
     InitializeComponent(); 
     this.otherClass = otherClass; 
    }

然後你可以在MainWindow.xaml.cs中的任何地方引用它
