Random number generator problem

You are right. But if you want to generate a 50 digit number, you should use a bigger range..

See this description from MSDN

"The random number generation starts from a seed value. If the same seed is used repeatedly, the same series of numbers is generated. One way to produce different sequences is to make the seed value time-dependent, thereby producing a different series with each new instance of Random. By default, the parameterless constructor of the Random class uses the system clock to generate its seed value, while its parameterized constructor can take an Int32 value based on the number of ticks in the current time. However, because the clock has finite resolution, using the parameterless constructor to create different Random objects in close succession creates random number generators that produce identical sequences of random numbers. The following example illustrates that two Random objects that are instantiated in close succession generate an identical series of random numbers."

You should set the min, max range Random.Next[^]

Random rnd  = new Random();
//inside your loop use it like
int newNumber = rnd.Next(0,7); // gets the random number between 0-7

for (int i = 0; i < 50; i++)
{
RandomizeAnswers();
}
 
public void RandomizeAnswers()
{
int x = rn.Next(0,7);      //it will display values between 0,7; confirm
// Then printing...
Console.WriteLine(x);
} 

Dont hesitate in asking any Question

Thanx

Try using this

int x = rn.Next() % 7;

Maybe it helps you.

This might solve your problem:

Random rand = new Random((int)DateTime.Now.Ticks);
int numIterations = 0;
numIterations=  rand.Next(0, 7);
Response.Write(numIterations.ToString());

Radnom r = new Radnom();
int temp;
for (int i =0; i<=7; i++)
{
temp = r.next(0,7);
Console.WriteLine(temp);
}

First you should specify a seed in your Random() constructor. As siny13 said you should use (int)DateTime.Now.Ticks to insure that each new instance wont return the same sequences.

Also you are using the same max value of 7 so that limits how random you can have it.
Also your loop is iterating 50 times so your going to have a lot of duplication.
