class - Problems with random # generators in c# (EDITED) -

i have in main, set objects , call player class. sorry lack of comments in code.

        player myplayer;     myplayer = new player();     hiders[] myhiders = new hiders[4];        (i = 0; < 4; i++)     {         myhiders[i] = new hiders();     }      while (foundall == false)     {         myplayer.move();         (i = 0; < 4; i++)         {             myhiders[i].displaydistance(myplayer.x, myplayer.y);         }         (i = 0; < 4; i++)         {             myhiders[i].checkcapture(myplayer.x, myplayer.y);         }          foundall = true;         (i = 0; < 4; i++)         {             if (myhiders[i].found == false)             {                 foundall = false;             }         }     }     console.writeline("you win!"); 

and these classes

    class player {     public int x;     public int y;      public void move()     {         string buffer;         console.writeline("where move?");         buffer = console.readline();         if (buffer == "u")         {             x++;         }         if (buffer == "d")         {             x--;         }         if (buffer == "l")         {             y--;         }         if (buffer == "r")         {             y++;         }     } } class hiders {     private int x;     private int y;      public bool found;     int[,] map = new int[10, 10];     random myrandom = new random();     int randomhx;     int randomhy;      public hiders(int hx, int hy)     {         myrandom = new random();         randomhx = myrandom.next(1, 10);         randomhy = myrandom.next(1, 10);     }      public hiders()     {      }      public void displaydistance(int px, int py)     {         double distance;          distance = math.sqrt(math.pow(x - px, 2) + math.pow(y - py, 2));          console.writeline(distance);     }      public void checkcapture(int px, int py)     {         if (randomhx == px & randomhy == py)         {              found = true;           }     } } 

all of hiders getting same value. how make change 1-10. should working.

each instance of hiders instantiating own instance of random. since being instantiated simultaneously, , random uses system clock default seed, instances of random produce same value sequence. recommendation have instances of hiders share single instance of random.
