El problema es que tienes que inicializar el array. dale el tamaño maximo.

Código:

  
string[] weekDays = new string[7];



      switch (DiasSemana)
      {

          case "Lu-Vi":

              weekDays = new string[] { "Monday", "Tuesday", "Wednesday", "Thursday", "Friday" };

              break;



          case "Lu-Dom":

              weekDays = new string[] { "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday" };
              break;



          case "Lu-Sab":

              weekDays = new string[] { "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday" };

              break;

      }     


                       foreach (string dia in weekDays)

                           MessageBox.Show(dia);
