VB,这个程序为什么会下标越界，最后的数组为什么没有只有A2的元素而没有A1的元素

A = Array(Join(A1, ","), Join(A2, ","))这个A中有2个元素，最大下标是1，所以For i = 0 To 9肯定下标越界如果你要直接输出A：Label1.Caption = join(A)如果你想将这A1，A2二个数组合二为一：A = Array(Join(A1, ","), Join(A2, ","))A=join(a,",")
‘先将上面的数组A转化为以逗号分隔的字符串（因为A的二个元素join(A1,",")和join(A2,",")是用逗号分隔的字符串）然后再用split按逗号分隔为数组：A = split(a,",")这样如果你A1和A2加起来有10个元素...

A = Array(Join(A1, ","), Join(A2, ","))这句有问题。这句的意思是将A1和A2作为A中的一个元素来合并的。数组合并的话，可以考虑自己写个函数。用循环也行，用copymemory也可。...

A = Array(Join(A1, ","), Join(A2, ","))这样A只有2个成员如果A(2)就超了A(0) = Join(A1, ",")就是A1数组每个成员用，并为一个字符串如果要合并数组，不能这样写依次传值...
