问题描述

我不知道为什么不能将else语句中的索引分配给整数数组.

I don't know why I can't assign the index in my else statement to my integer array.

每次我的程序转到else语句时，它都会中断，并显示System.Index.OutOfRangeException.

Everytime my program goes to the else statement it breaks saying System.Index.OutOfRangeException.

有什么建议吗?

推荐答案

声明数组时，必须说它的大小(可以容纳多少个元素，哪个范围从0到size-1)

When you declare an array, you have to say how big it is (how many elements it can hold, which will range from 0 to size-1)

您要声明输出数组的大小为零！

You are declaring the output array with a zero size!

int indexTwo = 0;
int[] output = new int[indexTwo]; // zero-element array!

因此，任何设置数组元素的尝试都将导致OutOfRangeException.

So any attempt to set an element of the array will result in an OutOfRangeException.

查看您的代码，索引可以从0循环到maxsize-1(maxsize元素).因此output []至少必须那么大.将声明更改为:

Looking at your code, index can loop from 0 to maxsize-1 (maxsize elements). And so output[] must be at least that big. Change your declaration to:

int[] output = new int[maxsize];
