C＃一次隐藏多个图像 [英] C# hide multiple images at once

问题描述

我在一个函数中一次创建50个奇数（星星）。 将这些星星的可见度设置为一次隐藏的好方法是什么？ - 或者只是摧毁星星。

I create 50 odd (stars) at once in a function.  What is a good way to set the visibility of these stars to hidden in one go? - or just destroy the stars.

谢谢，我对C＃相对较新

Thanks, I'm relatively new to C#

public void showStars() {
                for (int i = 0; i < 50; i++)
                {
                    Image aStar = new Image();
                    aStar.Width = 20;
                    aStar.Height = 20;
                    aStar.Visibility = Visibility.Visible;
                    aStar.HorizontalAlignment = Windows.UI.Xaml.HorizontalAlignment.Left;
                    aStar.VerticalAlignment = Windows.UI.Xaml.VerticalAlignment.Top; 
                    aStar.Source = new BitmapImage(new Uri("ms-appx:///Assets/star_small.png", UriKind.Absolute));

//注意我剪了随机为了简单起见，这里的东西是
double yLocation =（MainPage.ActualHeight / 2）* xRandD;
double xLocation =（MainPage.ActualWidth）* xRandD;
aStar.Margin =新厚度（xLocation，yLocation，0,0）;
MainPageGrid.Children.Add（aStar）;
}

}

//Note I cut the random stuff out here for simplicity double yLocation = (MainPage.ActualHeight / 2) * xRandD; double xLocation = (MainPage.ActualWidth) * xRandD; aStar.Margin = new Thickness(xLocation, yLocation, 0, 0); MainPageGrid.Children.Add(aStar); } }

推荐答案

有两种方式。

1。要么改变每颗恒星的可见度，要在for循环中折叠。

1. Either change the visiblity of each star to collapsed in a for loop.

2。或更改包含星星的容器的可见性.i.e MainPageGrid.Visibility = System.Windows.Visibilty.Collapsed;

2. Or Change visibility of container containing stars .i.e MainPageGrid.Visibility=System.Windows.Visibilty.Collapsed;
