Using String Array As Object Argument

So I have a class that has an argument of a string array. What I want to do is store multiple strings to this array that is part of this class. The code looks something like this:

//Class part of it. Class is called "Event"//

public class Event
{
   public string [] seats= new string [75];

   public Event(string[] seats)
   {
      this.seats=seats;
   }
}

// the main code that uses said Class

string[]seatnumber=new string[75];
Event show= new Event (seatnumber[]); //And that is where the error comes in. 

Any help would be greatly appreciated!
