你可以看到里面有很多愚蠢的东西。我唯一不能做的是让随机数生成器出现，使用一个名称，即用户想要的次数。这是一个Windows窗体应用程序
你可以看到我把它们叫做oneRoll和twoRoll等等所以我得到了不同的值但是我想让oneRoll出现的次数和用户想要的不同并且给出不同的数字
正确-所以您需要某种形式的集合。例如:
List<int> rolls = new List<int>();
for (int i = 0; i < desiredRolls; i++)
{
rolls.Add(randGen.Next(1, 7) + randGen.Next(1, 7));
}
然后以类似的方式执行所需的其他操作，即循环。您甚至可能不需要存储所有的滚动-如果您只是增加出现次数，您可以使用:
for (int i = 0; i < desiredRolls; i++)
{
int roll = randGen.Next(1, 7) + randGen.Next(1, 7);
arrNumOccurrence[roll]++;
}
基本上不清楚你的赋值是什么，但是集合和for循环的混合可能会让你走上正确的轨道。
每次都用"Seed" 1初始化随机数生成器。不要那样做。这保证了序列总是相同的。在循环之前初始化生成器一次:
Random random = new Random();
for (int i = 1; i < numrolls; i++)
{
i = random.Next(1, 7) + random.Next(1, 7);
rolls = rolls + i;
}
这听起来像是你试图建立一个频率表，显示特定骰子滚动的频率(例如，理论上，从长远来看，骰子的每个值应该均匀地发生)。应该执行以下操作:
- 计算每个骰子有多少面(不是所有骰子都是6面)。
- 计算出你想同时投多少骰子。
- 每次掷骰子返回的域(可能值的集合)是掷出的骰子数和每个骰子上的面数的函数。例如，如果你投掷2个6面骰子，结果的定义域是一个2和12(包括12)范围内的整数，因为6面骰子的点数是1-6。对于像10面骰子这样的东西，范围通常是0-9(只是为了混淆)，所以投掷2个10面骰子的域是0-99范围内的整数。
- 计算所需的迭代次数。你可以把它叫做样本量:你要掷多少次骰子来检验你的假设?
- 正如@Jon Skeet指出的那样，你需要某种类型的集合来累积频率计数。您需要的是某种类型的键集合，其中集合的键是掷骰子的值，值是频率—特定骰子掷出的次数。因此，集合的大小显然取决于强制转换的域。注意"键集合"并不一定意味着"字典"或"哈希表":数组是[非正式的]键的，数组元素的索引作为键值。
- 对于指定的每次迭代，投掷骰子并将特定结果的频率计数增加1。
简单!
编辑说明:你只需要一个单一的熵源(随机数生成器)。
