Is it possible to make array size size depended on the atribute value(int)? c# -

now question how can make when make new object type trip, arrayofpeople size of value numberofrooms?

class trip {     private person[] arrayofpeople;      public person[] arrayofpeople { return arrayofpeople; }         set { arrayofpeople = value; }  }  class ship   {      private int numberofrooms;       public int numberofrooms     {         { return numberofrooms; }         set { numberofrooms = value; }     }  } 

i thinking of making numberofrooms static , in trip constructor setting arrayofpeople = new person[ship.numberofrooms] not sure if right aproach. feel free correct me if wrong.

the comments in code answer question, check out :)

public class trip {     // define constructor trip takes number of rooms     // provided ship.     public trip(int numberofrooms)     {         this.arrayofpeople = new person[numberofrooms];     }      // removed field arrayofpeople becuase if     // going set , return array without manipulating     // don't need private field backing, property.     private person[] arrayofpeople { get; set; } }  public class ship {     // define constructor takes number of rooms ship     // ship knows it's room count.     public ship(int numberofrooms)     {         this.numberofrooms = numberofrooms;     }      // removed numberofrooms field same reason     // above arrayofpeople     public int numberofrooms { get; set; } }  public class myshipprogram {     public static void main(string[] args)     {         // create ship x number of rooms         var ship = new ship(100);          // can create trip using ship's number of rooms         var trip = new trip(ship.numberofrooms);     } }
