魔兽密保卡效果，精通数组的大虾请进！
我想做一个类似魔兽密保卡的系统：密保卡如下
但我的数组学的不好，哪位高人帮忙解决下
所要效果如下
登录账号时随即生成6个字母 比如 AEBDHF
那吗需要用户从密保卡上找到对应的数字填入才能验证成功登录
验证是先找行再找列 AEBDHF 对应的数字为115432
A B C D E F G H I J K L M N
A 11 12 13 14 15 16 17 18 19 20 21 22 23 24
B 25 26 27 28 29 30 31 32 33 34 35 36 37 38
C 39 40 41 42 43 44 45 46 47 48 49 50 51 52
D 53 54 55 56 57 58 59 60 61 62 63 64 65 66
E 11 12 13 14 15 16 17 18 19 20 21 22 23 24
F 25 26 27 28 29 30 31 32 33 34 35 36 37 38
G 39 40 41 42 43 44 45 46 47 48 49 50 51 52
H 53 54 55 56 57 58 59 60 61 62 63 64 65 66
我想应该是用二维数组吧
很紧急 高手帮忙 小弟不甚感激

验证是先找行再找列 AEBDHF 对应的数字为115432
是怎么找的，我怎么还没有看出来名堂……
雪雨星风 发布留言 2008-6-17 12:55
最上面不是有一行字母吗
左边也有列字母
要想找到唯一的数字必须根据横坐标和纵坐标找交叉点吧
产生的字母是先根据横坐标（也就是行）和纵坐标（也就是列）产生的
比如产生的ED 意思就是先在行上找到E再在列上找到D 他们相交的那个数就是要验证的数 57
hebingbing 发布留言 2008-6-17 13:01
哦，那样的话就比较好找了啊……
比如一个数组a，则第一行就是a[0,0]--a[0,26]然后一次类推……
比如要找DE，D是第四个，E是第五个，则要的数组就是a[3,4]……
雪雨星风 发布留言 2008-6-17 15:05
是啊 但是如何判断？[em04]
hebingbing 发布留言 2008-6-17 15:07
那你就事先将数组赋值啊，然后判断是否输入相等啊……

你运行下看看 最终结果显示出来了 但是它对应的字母组取不到[em10]
hebingbing 发布留言 2008-6-17 18:18
那ABCD这些字母干什么啊，数组中不要保存这些字母，但是在网页中显示重来就可以了嘛……

实例化生成器内错误
为什么把myArray[rdm.Next(1, 12), rdm.Next(1, 10)]这就写在循环内?
每循环一次变化一次 怎么比较啊?
雪雨星风 发布留言 2008-6-18 13:30
只要能产生字母可以验证成功
只是有时会出现取不到值 和 超出范围[em04] [em04]
191638141 发布留言 2008-6-18 16:54
让再说一次吗?
没取到值原因:
你每循环一次 随机产生一次 当循环几次还没取到值,这时随机数随到你前面循环的位置 你能取到值?比如 你循环X-2次 Y-3次 当随机产生为myarry[1,],myarry[1,..] ...或者myarry[2,1],...myarryp[2,2]你能取到相等值吗?
超出范围原因:
当你X循环9次以上,Y循环随便循环几次的时候 你的myarry[y,x]能不超出范围.
行和列的数目又不是相等的..
ps:不要一味的个人主义 好的建议就要先考虑再做判断 不要浪费大家的所谓的无意义的时间.
