0到20秒之間的隨機時間？

Question

如何創建一些隨機時間，如10秒。所以當我點擊按鈕時，我必須等待10秒才能看到新的按鈕？我的問題是如何創建隨機時間？而且它必須是在XAML

我的代碼：

public void randomButton() 
     {    
      newBtn.Content = "A New Button"; 
      Random myRandom = new Random(); 
      int rand1 = myRandom.Next(0, 400); 
      int rand2 = myRandom.Next(0, 400); 
      panelButton.Children.Add(newBtn); 

      Canvas.SetLeft(newBtn, rand1); 
      Canvas.SetTop(newBtn, rand2); 

      iRandom = row.Next(-350, 350); 
      newBtn.Click += newBtn_Click; 
      newBtn.Margin = new Thickness(iRandom, iRandom, 0, 0); 
     } 

     private void newBtn_Click(object sender, RoutedEventArgs e) 
     { 
      *// here i want the random time to happen!* 
      iRandom = row.Next(-350, 350); 
      newBtn.Margin = new Thickness(iRandom, iRandom, 0, 0); 
     } 

請幫助我，我真的很想知道它！對不起，我的英語不好！

Answer 1

private async void newBtn_Click(object sender, RoutedEventArgs e) 
{ 
    // here i want the random time to happen! 
    await Task.Delay(5000); // 5 sec, make it random 

    iRandom = row.Next(-350, 350); 
    newBtn.Margin = new Thickness(iRandom, iRandom, 0, 0); 
}
