The greedy snake game written in C #, simple

These days playing mobile phone greedy snake play into the fan, want to write a play on the computer, also as a programming practice.

Greedy Snake game demand:
1. Play: Similar to Nokia mobile phone on the greedy snake, but with the keyboard key or mouse to control the movement of snakes.
2. Appearance: In order to reduce the difficulty, just write a rectangle on a form to show the location of the greedy snake movement, the greedy snake is like the kind of Nokia mobile phone, with a few squares composed on the line.
3. Eat beans: Snake every eat a bean, the length of the snake to increase one, score plus 5 points. (like a snake without beans)
4. Death: The death of a snake when it collides with a wall or its own body.

Running environments and programming languages
As a result of this time learning C #, the natural idea is to use the C # language to write this little game. After we complete this demo, we'll use Java to implement it.

Programming bad; Visual Studio. NET 2003 Chinese version
Operating system: Windows 2000 or above.

Use object-oriented usage to abstract some of the following classes:
A floor class that represents the place where snakes move.
Snake class, indicating snakes
Block class, which represents the blocks that make up a snake, where we think the snake object is made up of a piece of block object.
Bean class, which means beans,
There are detailed comments in the source program.

Next Update features:
1. Add the scoring function. The snake eats a single bean and scores one.
2. Snake speed increases with score.
3. Add keyboard control function, use arrow keys to control the direction of snake movement
