Choosing a label at random

Thomas Mifsud

I'm a relative beginner with C#/Visual Studio and have recently been trying to put together a minesweeper game as practice. Does anybody know how I would choose 20 labels out of 100 on a form at random? I can't seem to think of any way.

Hi.
Here's a peace of code:

//CODE START *********************************************************
Label[,] MyLabels = new Label[10, 10];

for(int i = 0; i < 10; i++
   for(int j = 0; j < 10; j++)
   {
      MyLabels[i,j] = new Label();
      MyLabels[i,j].Parent = this;   // Or You can Add MyLabels[i,j] to your form controls
      // Set MyLabels Location According to i, j if you want to display a 2D array
      //Set MyLabels Size, Text etc.
   }

int[] numbers = new int[20];   // if you want, not to have repeated numbers, you need an array.
bool repeated = false;

Random R = new Random(100);

for(int i = 0; i < 20;)
{
   repeated = false;
   int temp = R.Next();

   for(int j = 0; j < i; j++)
      if(numbers[j] == numbers[i])
         repeated = true;

   if(repeated == false)
   {
      numbers[i] = temp;
      i++;
   }
}
//CODE END************************************************************

I hope it helps.

create an array of the labels and use something like Random, search for Random in your C# version of Help.
