Yêu cầu:

1) Tạo lớp đối tượng Project gồm các trường thông tin: string name (tên đề tài), string projectType: Nhóm dự án (group chỉ nhận 3 giá trị là Development & Design Website, Website Developer, Application Developer) - 1 điểm

2) Tạo lớp đối tượng Group gồm các thuộc tính: string name (tên nhóm), string center: tên trung tâm aptech, project (kiểu dữ liệu là Project) - 1 điểm

Viết getter/setter cho tất cả các thuộc tính của lớp đối tượng - 1 điểm

Viết hàm Input, Display của đối tượng trên - 2 điểm

Tạo class Program có chưa 1 method Main. Yêu cầu khai báo mảng List<Group> groupList. Yêu cầu nhập vào ngẫu nhiên N nhóm (N có giá trị từ 2 tới 10) - 5 điểm

Tạo 1 delegate như sau

delegate void ShowInfor();

Khai báo 1 đối tượng delegate ShowInfor -> Thực hiện quản lý tất cả các phương thức Display() của tất cả các đối tượng Project trong đối tượng này. Yêu cầu gọi thực thi delegate vừa được tạo ra.  - 5 điểm
