Question

I’m currently working on a C# program that creates a List, of object Task, the object Task is a base class and many other inherit from it. What I want to is compare the type of one of the object within said list to see which form should be opened in order to edit it.

This is the code I have already created.

private void itemEdit_Click(object sender, EventArgs e)
    {
        int edi = taskNameBox.SelectedIndex;
        Task checkTask = todoList.ElementAt(edi);

        if(checkTask.GetType is Note)
        {
            noteBuilder editNote = new noteBuilder(todoList);
            editNote.Show();
        }

        else if(checkTask.GetType is extendedTask)
        {
            extendedTaskBuilder editTask = new extendedTaskBuilder(todoList);
            editTask.Show();
        }

        else if(checkTask.GetType is Reminder)
        {
            reminderBuilder editReminder = new reminderBuilder(todoList);
            editReminder.Show();
        }

        else if (checkTask.GetType is Appointment)
        {
            appointmentBuilder editAppointment = new appointmentBuilder(todoList);
            editAppointment.Show();
        }
    }

On a secondary note would it be easier if instead of passing the list between the forms and generating a new object of the form that display information that I instead pass a single object between forms and just update the form every time a new element is added to the list.

Many thanks

Have you tried checking like this:

if (checkTask is Note)
{

}
