This application uses one instance of the **Random()** class in the object **rnd**. It also allocates enough space to hold the totals for scores 3..18 in the array **Rolls\[\]**. [Member][] [functions][] **OneDice()** returns a value between 1 and 6 - **rnd.Next(n)** returns values in the range 0..n-1, while **ThreeDice()** calls **OneDice()** three times. The [constructor][] for the **RollDice()** clears the **Rolls** array then calls **ThreeDice()** however many times (10 million in this case) and increments the appropriate **Rolls\[\]** element.

此应用程序在对象**rnd中**使用**Random()**类的一个实例。 它还分配了足够的空间来保存数组**Rolls \[\]中**得分3..18的总数。 [成员][Member] [函数][functions] **OneDice()**返回1到6之间的值**-rnd.Next(n)**返回0..n-1范围内的值，而**ThreeDice()**调用**OneDice()** 3次。 **RollDice()**的[构造函数][constructor]清除**Rolls**数组，然后多次调用**ThreeDice()** (在这种情况下为1000万)，并递增适当的**Rolls \[\]**元素。

The last part is to print out the generated totals to see that it generates throws in accordance with the probabilities. A 6 sided dice has an average score of 3.5, so three dice should average about 10.5. The totals for 10 and 11 are roughly the same and occur about 12.5% of the time.

最后一部分是打印出生成的总数，以查看它根据概率生成了抛出。 6面骰子的平均得分为3.5，因此3个骰子的平均得分约为10.5。 10和11的总数大致相同，大约占时间的12.5％。

Here is the output of a typical run. It takes no more than a second. Because it's a console application, I included a

这是典型运行的输出。 只需要一秒钟。 因为它是一个控制台应用程序，所以我包含了一个

Console.ReadKey();

To wait until you hit a key before closing.

等待直到您敲关键再关闭。
