How to check if an item has already been entered in a list in C #

  • Classes list exists
  • Within this list I put class objects
  • Each object has (string) nameTurma.Text & a numerical value (int) numericUpDown1.Value

  • I use the addTurma method to place the objects in the groups list 

        public static List<turma> turmas = new List<turma>();

    public static void addTurma(turma x)
    {

        turmas.Add(x);

    }
 turma x = new turma(nomeTurma.Text,(int)numericUpDown1.Value);
 //Se nomeTurma.Text não exite na lista turmas
  {
  turma.addTurma(x);
  }

    • I just want to add class-type objects that do not have the same name, ie verify that stringTurma.Text already exists in the / strong>
