i have 7 teams and i want with using the class random and the next method(a,b), i want to create and save the results randomly.

i'll tell you what the program dowes so, you can understand what i want to do:
firstly, when the program runs, it will ask for a username and a password. Then, the user will give the dateConduct so, the randomly creation begin.

public class Game{

Other.Date dateConduct;
Team[] Teams;
Team winner;
bool conduct=false;

}

public class Team{

string name;
string captain;
int points;
}

i want you to tell me how i can create randomly results for the 7 teams. Using the randonm Class and the method Next(a,b)

Well, this is how to use the Random class and Next(int a, int b,)

Random rnd = new Random()

//Generates a random number between 0 and 10
points = rnd.Next(0,10);

So you could give the team a method which when called uses the above to generate a points score for them? Obviously changing the upper and lower bounds as you see fit.

MSDN: Here

From what I understand Mitja, it is used to randomly generate a points total for each of the seven teams specified, hence the team having an int points;

:)

But it has no point in this.
Points are (in my opinion) the points -for football (in europe):
3 - for winning
1- for equal
0 - for loosing

---

So really dont see the point in using Random, only in case if he want to shuffle teams in between to create, lets says, some kind of championship.
Who knows... :)

You want it like football scores?

Could do this then for each "match fixture"

Random rnd = new Random();
int[] availablePoints = new int[3] { 0, 1, 3 }

points = availablePoints[rnd.Next(0,2)];

Giving a random result of either 0 1 or 3 when applied to the array :)

Edit: If no one beats me to it i'll make a match fixture thing tonight when back from work

Freedom - PLEASE next time you write into here, define EXACTLY what you wound want from this project to do. But I mean exactly - not "this is what I want it to do", or "yes, random scores".

We dont know now what to think, you saw me I have guessed what you had been thinking about.

Agree with Mitja, I'll write a bit of team code and it'll be up tonight regardless of what you want, gives me something to do :)

Its finally done, quite basic but shows the concepts of using the random class to create a tournament.

Points to note about the code below:
- Tournament plays only 20 games
- There is no validation in terms of all teams playing even amounts of matches
- Its very basic :)

Hopefully though it'll give you an idea on how the random class can be used.

            Console.WriteLine();
