第二个没读懂，你换个方式试试，如：

'Dim bts() As Byte = My.Computer.FileSystem.ReadAllBytes("")

Dim bst As System.IO.BinaryReader = New System.IO.BinaryReader(System.IO.File.OpenRead("D:\Program Files(Green)\人机对战五子棋-绿色免安装单机版v1.0.exe"))

Dim bs() As Byte

Const aLength As Integer = 50000

Do

bs = bst.ReadBytes(aLength)

Console.WriteLine(bs.Length)

Loop Until bs.Length  aLength

bst.Close()

文件读到最后一块总会小于指定长度的，你的代码先定义数组长度，然后再读取，这样最后读取的一块二进制数组必然有一部分无效的。

五子棋游戏程序设计（VB）

五子棋的AI构想 有句话叫“当局者迷，旁观者清。”，但这句话在由AI所控制的计算机玩家上是不成立的，因为计算机必须知道有那些获胜方式，并计算出每下一步棋到棋盘上任一格子的获胜几率，也就是说，一个完整的五子棋的AI构想必须：

1、能够知道所有的获胜组合； 2、建立和使用获胜表； 3、设定获胜的分数； 4、使电脑具有攻击和防守的能力； 一、求五子棋的获胜组合 在一场五子棋的游戏中，计算机必须要知道有那些的获胜组合，因此我们必须求得获胜组合的总数。我们假定当前的棋盘为10*10。 （1）计算水平方向的获胜组合数，每一列的获胜组合是：6，共10列，所以水平方向的获胜组合数为：6*10=60 （2）计算垂直方向的获胜组合总数，每一行的获胜组合是：6，共10行，则垂直方向的获胜组合数为：6*10=60 （3）计算正对角线方向的获胜组合总数，正对角线上的获胜组合总数为6+（5+4+3+2+1）*2=36 （4）计算反对角线方向的获胜组合总数，反对角线上的获胜组合总数为6+（5+4+3+2+1）*2=36 ，这样所有的获胜组合数为：60+60+36+36=192 二、建立和使用获胜表 我们已经计算出了一个10*10的五子棋盘会有192种获胜方式，这样我们可以利用数组建立获胜表，获胜表的主要作用是：1，判断当前的获胜方式是否有效；2，判断当前的获胜方式中到底有多少子落入该获胜组合中。详细的使用您将在后面的程序中可以看出。 三，分数的设定 在游戏中为了让计算机能够决定下一步最佳的走法，必须先计算出计算机下到棋盘上任一空格的分数，而其中最高分数便是计算机下一步的最佳走法。 原理：我们判定当前讨论的空格与当前讨论的点有几种获胜的方式，有几种该空格就加几分。这种原理初听起来似乎是无法入手，没关系，当您了解我们后面的程序后您就会明白这种决策原理了。 这种决策有一些缺陷，因为如果只根据这个模型设计，就有可能出现电脑或玩家有三个子连成一线的时候，计算机却判断不出，它认为其他某些空格是当前的获胜的最佳位置而不去攻击或防守。没关系我们完全可以通过一个加强算法来改变当前的分值情况，也就是说当电脑或玩家有三个子或四个子连成一线时，我们通过加强算法将当前与三个子或四个子有关的空格的分值提高，从而可以弥补这一缺憾。 四、攻击与防守 以上的方式，事实上计算机只是计算出了最佳的攻击位置，为了防守我们还应计算当前玩家的最佳的攻击位置。这样有什么用呢？道理很简单，如果玩家最佳攻击位置的分数大于计算机最佳攻击位置上的分数，那么计算机就将下一步的棋子摆在玩家的最佳攻击位上以阻止玩家的进攻，否则计算机便将棋子下在自己的最佳攻击位置上进行攻击。 事实上，这个AI构想是很强大的如果你不是很厉害的五子棋高手的话，可能很快会被计算机打败。我在联众上可是中级棋手啊，跟这种构想打的时候胜率也不是很高。 使用vb.net编写五子棋 一、编写前的准备： 1、用计算机的思想描述整个下棋的过程 考虑步骤： （1）为了简便我们可以先让电脑先走第一步棋，电脑每走一步就会封掉许多玩家的获胜可能情况。 （2）当玩家走棋的时候我们首先应该考虑玩家走棋的合法性。 （3）如果合法，那么玩家也会封掉许多电脑的获胜的可能情况。 （4）电脑的思考路径：首先判断当前玩家和电脑的所有获胜组合是否需要进行加强赋值，

是进行加强赋值，否则进行普通的赋值。 （5）比较当前玩家和电脑谁的分值最大。将分值最大的点作为电脑的下一步走法。 2、利用vb.net窗体和图形工具建立五子棋的棋盘界面 （1）添加一个picturebox控件 作用：使用picturebox控件绘制棋子和棋盘 （2）添加一个label控件 作用：显示当前的获胜标志，也就是当某一方获胜或和棋时显示此标签。 （3）添加一个mainmenu控件 作用：控制游戏的开始或结束 （4）添加一个mediaplay组件 作用：使程序可以播放音乐。 3、设置整体框价 我们采取10*10的棋盘，为主要的平台。利用数组定义整个棋盘桌面，利用数组定义获胜组合以及获胜标志等。 二，声明全局数组和变量 定义虚拟桌面： Dim table(9, 9) As Integer 定义当前玩家桌面空格的分数： Dim pscore(9, 9) As Integer 定义当前电脑桌面空格的分数： Dim cscore(9, 9) As Integer 定义玩家的获胜组合： Dim pwin(9, 9, 191) As Boolean 定义电脑的获胜组合： Dim cwin(9, 9, 191) As Boolean 定义玩家的获胜组合标志： Dim pflag(191) As Boolean 定义电脑的获胜组合标志：

Dim cflag(191) As Boolean 定义游戏有效标志： Dim theplayflag As Boolean 三、初始化游戏 '*****************************************************************************

C#写五子棋，如何实现，落子

软糖有一个五子棋源码，不过是VB.net的。

棋盘是用int[,]二维数组做的，值为0就是空，1是白方，2是黑方。

落子判断值是否为0，然后根据当前玩家的赋值为1或2。
