随机无代问题 [英] Random No generation problems
问题描述
如何调用一些
人建议的随机数生成器。理想情况下，我想要做的是实例化随机数。
生成器，其种子值不重复值，并且可以从任何类调用
，因为我必须从
几个不同的类别调用随机数发生器。
这是我的代码：
使用系统;
class cMain
{
static void Main（）
{
}
}
公共类cGetRandom
{
静态随机rand = new Random（）;
private static int GetRandom （）
{
锁定（兰特）
{
返回rand.Next（）;
}
}
}
公共类cClass1
{
private static int Class1（）
{
int lnRand = 0;
lnRand = cGe tRandom.rand.Next（1,49）;
}
}
TIA

将Environment.TickCount传递给Random构造函数。那应该是
为发电机播种并为你提供所需的随机性。
你好Chris，
是的我看到类似于Random（Environment.TickCount）的东西是
这样：
随机（未选中）（（int） DateTime.Now.Ticks））;
但我想知道的是我是否每次都需要创建一个Random
构造函数的实例在类中生成随机数。你需要看看我必须在几个不同的类中生成随机数，所以理想情况下我想要只使用一次构造函数，就像你在C ++中那样使用
br />
（srand（（无符号）时间（NULL））每次都得到一个随机数然后
总是使用同一个实例生成一个随机数。这可能吗？
谢谢
Roy

Hi,
How do I invoke the random number generator that was suggested by a few
people. Ideally, what I would like to do is to instantiate the random no.
generator with a seed value that does not repeat the values and that can be
called from any class, as I have to call the random number generator from a
few different classes.
Here is my code:
using System;
class cMain
{
static void Main()
{
}
}
public class cGetRandom
{
static Random rand = new Random();
private static int GetRandom()
{
lock ( rand )
{
return rand.Next();
}
}
}
public class cClass1
{
private static int Class1()
{
int lnRand=0;
lnRand=cGetRandom.rand.Next(1, 49);
}
}
TIA

Pass Environment.TickCount into the Random constructor. That should
seed the generator and give you the randomness you need.
Hi Chris,
Yes I have seen something similar to Random(Environment.TickCount) that is
like this:
Random(unchecked((int)DateTime.Now.Ticks));
but what I want to know is if I have to create an instance of the Random
constructor every time I want to generate a random number in a class. You
see I have to generate random numbers in a few different classes, so ideally
I would have like to just use a constructor only once just as you do in C++
(srand( (unsigned)time( NULL ) ) to get a random number every time and then
always use that same instance to generate a random number. Is that possible?
Thanks
Roy
