在C＃XNA中，每次游戏加载时如何在随机位置显示我的精灵？

I am having trouble with loading my sprites in random places when the game loads, I have currently got them set in specific positions as shown below:

我在游戏加载时在随机位置加载我的精灵时遇到问题，我现在已将它们设置在特定位置，如下所示：

BlackBallRectangle = new Rectangle(150, 300, 25,25);
BlackBallRectangle2 = new Rectangle(500, 400, 25, 25);
BlueBallRectangle = new Rectangle(500, 150, 25, 25);
GreenBallRectangle = new Rectangle(100, 500, 25, 25);
OrangeBallRectangle = new Rectangle(180, 200, 25, 25);
PinkBallRectangle = new Rectangle(260, 260, 25, 25);
RedBallRectangle = new Rectangle(300, 450, 25, 25);
YellowBallRectangle = new Rectangle(550, 300, 25, 25);

I have created a Random Randome = new Random(); but I am unsure if this is needed. Any help would be great as I need them to be in random places for each level

我创建了一个Random Randome = new Random（）;但我不确定是否需要这样做。任何帮助都会很棒，因为我需要它们在每个级别的随机位置

You have to make use of Random.

你必须使用随机。

Random Randome = new Random();
BlackBallRectangle = new Rectangle(Randome.Next(0, 150), Randome.Next(0, 300), 25, 25);
BlackBallRectangle2 = new Rectangle(Randome.Next(0, 500), Randome.Next(0, 400), 25, 25);
// the same thing for others

This Randome.Next(0, 150) generate a value between 0 and 150. You can replace minValue and maxValue to match your needs.

此Randome.Next（0,150）生成0到150之间的值。您可以替换minValue和maxValue以满足您的需要。

Note: If you make same instance of the class with the Random property, I recommend you to mark it as static, otherwise there are chances to generate for same clases type same set of values.

注意：如果使用Random属性创建类的相同实例，我建议您将其标记为static，否则有可能生成相同的clases类型相同的值集。
