C＃WPF排序號碼

Question

我正在做一個項目，其中包括一個彩票號碼發生器，然後將其保存到txt文件，但我有一個問題：我怎樣才能按升序排序數字，當每個數字是在一個不同的標籤？

代碼

static Random Gerar = new Random(); 
    public static readonly string FilePath = "ChavesEuromilhões.txt"; 

    public GerarChave() 
    { 
     InitializeComponent(); 
    } 

private void gerarNumeros() // method to generate numbers 
    { 

     int a = Gerar.Next(1, 50); 
     int b = Gerar.Next(1, 50); 
     int c = Gerar.Next(1, 50); 
     int d = Gerar.Next(1, 50); 
     int e = Gerar.Next(1, 50); 
     int f = Gerar.Next(1, 12); 
     int g = Gerar.Next(1, 12); 

     num1.Content = a.ToString(); 
     num2.Content = b.ToString(); 
     num3.Content = c.ToString(); 
     num4.Content = d.ToString(); 
     num5.Content = e.ToString(); 
     num6.Content = f.ToString(); 
     num7.Content = g.ToString(); 


    } 

    private void button_voltar_Click(object sender, RoutedEventArgs e) 
    { 
     MainWindow sw = new MainWindow(); 
     sw.Show(); 
     this.Close(); 

    } 

    private void button_Guardar_Click(object sender, RoutedEventArgs e) // save the number 
    { 
     using (StreamWriter writer = new StreamWriter(GerarChave.FilePath, true)) 
     { 
      if (num1.Content == null || num2.Content == null || num3.Content == null || num4.Content == null || num5.Content == null || num6.Content == null || num7.Content == null || comboBox.SelectedValue == null || Date_Picker.SelectedDate == null) 
      { 
       System.Windows.MessageBox.Show("Todos Os campos São de Prenchimento Obrigatorio!"); 
      } 
      else 
      { 
       writer.WriteLine(num1.Content + "," + num2.Content + "," + num3.Content + "," + num4.Content + "," + num5.Content + "," + num6.Content + "," + num7.Content + "," + comboBox.SelectedValue + "," + Date_Picker.SelectedDate.Value.Date.ToShortDateString());     
       writer.Close(); 
       System.Windows.MessageBox.Show("Chave Guardada!"); 
      } 

     } 
    } 

    private void button_ordenar_Click(object sender, RoutedEventArgs e) 
    { 

     // button to order the numbers 
    } 
    } 
} 

}

例如，你可以存儲在一個List<int>的整數，你只需撥打Sort上，如：

private readonly List<int> theNumbers = new List<int>(); 
private void gerarNumeros() // method to generate numbers 
{ 
    int a = Gerar.Next(1, 50); 
    int b = Gerar.Next(1, 50); 
    int c = Gerar.Next(1, 50); 
    int d = Gerar.Next(1, 50); 
    int e = Gerar.Next(1, 50); 
    int f = Gerar.Next(1, 12); 
    int g = Gerar.Next(1, 12); 

    theNumbers.Clear(); 
    theNumbers.Add(a); 
    theNumbers.Add(b); 
    theNumbers.Add(c); 
    theNumbers.Add(d); 
    theNumbers.Add(e); 
    theNumbers.Add(f); 
    theNumbers.Add(g); 
    theNumbers.Sort(); 

    num1.Content = a.ToString(); 
    num2.Content = b.ToString(); 
    num3.Content = c.ToString(); 
    num4.Content = d.ToString(); 
    num5.Content = e.ToString(); 
    num6.Content = f.ToString(); 
    num7.Content = g.ToString(); 
} 

private void button_ordenar_Click(object sender, RoutedEventArgs e) 
{ 
    if (theNumbers.Count == 7) 
    { 
     num1.Content = theNumbers[0]; 
     num2.Content = theNumbers[1]; 
     num3.Content = theNumbers[2]; 
     num4.Content = theNumbers[3]; 
     num5.Content = theNumbers[4]; 
     num6.Content = theNumbers[5]; 
     num7.Content = theNumbers[6]; 
    } 
}
