C# 而循环卡在代码的随机点上
我需要帮助，我有我的朋友帮我调试这段代码，我们发现代码在代码上的任意点停止，有时在第一个循环上，有时在最后一个循环上，等等。 代码只是用来制作一个9x9数独板，上面应用了所有的规则。当我分别测试每个模块时，它工作正常，并且打印出了一个做得很好的数独板，但这里的问题是，不知怎么的，它被卡住了。 我们将不胜感激C# 而循环卡在代码的随机点上,c#,loops,multidimensional-array,random,C#,Loops,Multidimensional Array,Random,我需要帮助，我有我的朋友帮我调试这段代码，我们发现代码在代码上的任意点停止，有时在第一个循环上，有时在最后一个循环上，等等。 代码只是用来制作一个9x9数独板，上面应用了所有的规则。当我分别测试每个模块时，它工作正常，并且打印出了一个做得很好的数独板，但这里的问题是，不知怎么的，它被卡住了。 我们将不胜感激 int[,] helpblock = new int[10, 10]; int[,] helplines = new int[10, 10]; int[,] helpcols = new i
