C # Health Package program

A small project written with a generic collection

1. To achieve a new medical checkup plan, and if you already have the medical plan can not be created again,

2. To implement the package list dynamic update, not add a health checkup package, in the package list will automatically add an item;

3. Add a check item to the current package list, there is no duplicate medical examination item in a medical examination plan;

4. Dynamic calculation plan current price;

5. Dynamic Dgvlist of the current package of the package list in the program;

6. Implementation of the removal of physical examination items:

Here is the implementation:

New Checkup Package:

Add a physical examination to the health plan and calculate the package price:

To delete a selected medical item:

Select a health plan in the package list to view specific items and package prices:

Cannot add duplicate packages, each plan cannot have duplicate medical items:

Here's the code:
