[Solved] Help translating to C#

I need some help translating this random number generator in C#. Not so much the output and the for loop structure and what not, but basically how the cstdlib, and ctime would translate to C#, and the srand((unsigned)time(0)); Can anyone help me out?

C++ Code:

Code: [Select]

#include <iostream>
#include <cstdlib>
#include <ctime>

using namespace std;

int main()
{
srand((unsigned)time(0));
int n = 0, k = 0;
// Roll 30 Times.
for (k = 0;k < 30;k++)
{
// Get the random number
n = (rand() % 4);
cout << n << endl;
}
return 0;
}

You want the System.Random class

Re: Help translating to C#

Yeah I had that originally, but I realized where my error was. I was using this code:

Code: [Select]

private int RandomNumber(int min, int max)
{
    Random random = new Random();
    return random.Next(min, max);
}
I thought about it while talking to Min about it. Then I realized it was using the same seed since I was re-instantiating it every time I called the function. So I made random a class-wide variable, and it does what I want now. But thanks TheDarkJay.

Re: [Solved] Help translating to C#

Code: [Select]

private int RandomNumber(int min, int max)
{
    static Random random = new Random();
    return random.Next(min, max);
}
Would have solved the problem the same and used only one Random class regardless of how many instances of the class were used ^.^ (At least I'm fairly sure that's how statics in C# functions work )

Probably not useful for this particular problem but still...
