关于类中多维数组的问题
圣诞节快乐，麻烦各位帮忙解惑。关于多维数组方法返回值的问题。有三个构造函数，Class1和Class2是关于多维数组返回的，Class3是一维数组返回的问题。
textbox1中输入一个值，在Class1和Class2进行多维数组运算，然后将计算结果返回到主程序中，return m1[0][0]返回的是多维数组的初值，return a[0]则返回的是一维数组的运算结果。请帮忙解决下。

例如：textbox1的值是2，计算结果在窗口中Label1和Label2中显示的是1, 3, 4, 2, 6, 4 4, 2, 3, 6 6, 5, 1；Label3中显示的是3，5，6，4，8，6
