c# practice problem. random number generator using lists instead of arrays

1. Declare 2 class level integer Lists to hold the random numbers.

   • There are 7 whole numbers chosen for the player.

   • There are 6 whole numbers chosen as the winning numbers.

2. Add the following user defined methods to your code:

   a) private void GenerateRandomNumbers(List numberList)

   • This method accepts one integer List as a parameter Lists are passed by reference, hence there is no need to pass back the List to the calling method.

   • This method will loop through the List generating random numbers between 1 and 49.

   • Add code that checks that the number has not been used before. b) private string BuildDisplayString(List numberList)

   • Inside this method, loop through the List that is passed in and add each element to a string variable.

   • Return this string to the calling method where it will display it to the appropriate label. c) privateintCompareTwoArrays(Listlist1,Listlist2)

   • This method will loop through one of the Lists. Each element of this List will checked against all elements of the second List checking for a match.

   • If a match is found, increment a variable holding the number of matching values when done, this value is passed back to the calling method.

3. Code the btnPlayer_Click( ) event handler method:

   • This event will require you to generate random numbers for the player and display these numbers to

     the appropriate label.

   • Use the appropriate methods you defined above.

4. Code the btnComputer_Click( ) event handler method:

   • This event will require you to generate random numbers for the computer the winning numbers

     and display them to the appropriate label.

   • The event will also determine the number of matching numbers between the winning numbers and the

     players numbers. Display this value to the appropriate label.

   • Use the appropriate methods you defined above
