C# 开发2048小游戏

　　这应该是几个月前，闲的手痒，敲了一上午代码搞出来的，随之就把它丢弃了，当时让别人玩过，提过几条更改建议，但是时至今日，我也没有进行过优化和更改（本人只会作案，不会收场，嘎嘎），下面的建议要给代码爱好的童鞋完成了。

更改建议：

a.当数字超过四位数时，显示的时候有部分被它的容器TextBox遮挡了，能不能把显示的数值变小点？答案是可以的。代码里有一段通过矩阵数据填充TextBox值的操作，可以在填充时，判断下数值长度，然后修改TextBox的文字大小。

b.玩游戏的时候，使用方向键移动时，焦点可能没有锁定在自定义控件的画布上，能不能使用方向键移动时，锁定画布？答案是可以的，不敢说出来，因为很简单，说出来就不值得提出这个问题让Reader来做了（哈哈）。

c.还有几条，真的记不住了，唉，老亦。

　　其实不难，就是多了点，杂了点，喜欢的可以拉走做毕业设计用，如果要说这里面有什么值得看的地方，我觉得应该没有吧，毕竟做的仓促，也没好好的修改。

1.应用程序的主入口点：文件名Program.cs，这个简单，可以略过

using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;
using System.IO;

namespace _2048
{
static class Program
{
/// <summary>
/// 应用程序的主入口点。
/// </summary>
[STAThread]
static void Main()
{
AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException);

Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}

static void Application_ThreadException(object sender, System.Threading.ThreadExceptionEventArgs e)
{
File.AppendAllText(AppDomain.CurrentDomain.BaseDirectory + "Exception.log", DateTime.Now.ToString() + "\t" + e.Exception.Message + Environment.NewLine);
}

static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
{
File.AppendAllText(AppDomain.CurrentDomain.BaseDirectory + "Exception.log", DateTime.Now.ToString() + "\t" + e.ExceptionObject.ToString() + Environment.NewLine);
}
}
}

2.用到的数据模型：文件名Unit.cs，这个简单，可以略过

using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;

namespace _2048
{
public class Unit
{
public Unit()
{

}

public Unit(int num, bool bMerge)
{
this._num = num;
this._bMerge = bMerge;
}

private int _num = 0;

public int Num
{
get { return _num; }
set { _num = value; }
}

private bool _bMerge = false;

public bool BMerge
{
get { return _bMerge; }
set { _bMerge = value; }
}

//private int _x = 0;

//public int X
//{
//    get { return _x; }
//    set { _x = value; }
//}

//private int _y = 0;

//public int Y
//{
//    get { return _y; }
//    set { _y = value; }
//}
}
}

3.自定义控件和算法（设计器和后台文件已合并）：文件名GridControl.cs，整个程序的核心内容都在这个文件里，包括2048游戏算法、自定义控件的伸缩、方向键移动控制等等吧，后半部分不用看了，设计器自动生成的，不可或缺，没什么嚼劲。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace _2048
{
public partial class GridControl : UserControl
{
/*
* 判断结束的必要条件：
* 无论如何移动（上、下、左、右），矩阵中没有空着的位置时，结束
*
*
*1. 初始化参数,初始化数量3
*2. 每次移动，相同数字合并加分
*3. 每次移动，在移动后的随机空格位置处产生一个新数
*/
private int _x = 0;

public int X
{
get { return _x; }
set
{
_x = value;
CreateTextBox();
}
}

private int _y = 0;

public int Y
{
get { return _y; }
set
{
_y = value;
CreateTextBox();
}
}

private Unit[][] _matrix = null;
private Random rand = new Random(DateTime.Now.Millisecond);
private int _score = 0;

public int Score
{
get { return _score; }
set { _score = value; }
}

public GridControl()
{
InitializeComponent();
}

public void InitControl()
{
/*初始化矩阵图，以下三个方法的顺序不能颠倒*/
this.InitMatrix();
this.InitParamter();
this.InputData();
}
