Array of dates returns object System datetime not the actual value of the array

Question is I have a function call "GetDatesBetween" what this does is looks at my two datepickers leave_s_dp and leave_e_dp and gets the dates between them. I then want to turn this array into a string for use in my full_range text box, But it always returns System.DateTime[]. Any help would be greatly appreciated.

public:
List<DateTime> ^GetDatesBetween(DateTime startDate, DateTime endDate)
{
    List<DateTime> ^allDates = gcnew List<DateTime>();

    for (DateTime date = startDate; date <= endDate; date = date.AddDays(1))
    {
            allDates->Add(date.Date);
    }



    return allDates;

}


private: 
System::Void submit_button_Click(System::Object^  sender, System::EventArgs^  e) {
             array<DateTime> ^dates = GetDatesBetween(leave_s_dp->Value.Date, leave_e_dp->Value.Date)->ToArray();

             //array<DateTime> ^dates = GetDatesBetween(leave_s_dp->Value, leave_e_dp->Value)->ToArray();


             String ^ days_between = dates->ToString();




             full_range_text->Text = days_between;


}
