count number

Hi, im beginner in c# and now im writing prog, that write 200 numbers from 1-50.I have to use arrays. Here is my code:
int[] talan = new int[200];
      Random slembi = new Random();
      for(int x=0;x<talan.Length;x++)
      {
        talan[x] = slembi.Next(1,50);
          ctr++;
        Console.WriteLine("Tala numer {0} er {1} ",ctr,talan[x]);
}


My q is how i can after the loop ask prog how many times like 4 or any other number came up and so on? Hope someone  can help me.
Thx
