Random.Next is not giving a random number

Question

Hi
This how I used the random but it always gives "1" index to indexOfAChosenListCell.
When I debug it it shows different values, but on regular running I get the same move every time..
What is the problem with Random , it's static not random... :)

internal Square getAutomaticMove()                      
{
            List<Square> LegalMovesArray = GetLegalSquares();
            Random randomListCell = new Random();
            int indexOfAChosenListCell = 0;

            if (CheckForLegalSquares())    
            {
                 indexOfAChosenListCell = randomListCell.Next(LegalMovesArray.Count-1);
            }

Answer 1

make randomListCell an instance variable and only initialize it once - otherwise you will keep getting the same numbers again.

From MSDN:

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.

Answer 2

Random.Next(Int32)

Returns a nonnegative random number less than the specified maximum

So the largest number you'll ever get is Count - 2, probably not what you wanted.
