C# IndexOutof RangeException
本文关键字：RangeException IndexOutof | 更新日期: 2023-09-27 18:07:02
我得到一个系统。IndexOutOfRangeException:索引超出了数组的边界。在EvEOreCalculator.Program.Main()当我试图运行我的编译代码(我使用c#)。对于用户的输入，这些值的范围可以达到50亿。所有保存大数的int变量和数组都已经转换为long类型。唯一剩下的int型就在标准的for循环中，用于遍历数组。
在我纠正compressedOreList数组中的数据之前，我没有任何问题，该数组和orelist都是整型，直到我开始得到超出范围的异常，它作为整型运行良好，两个表中的数字在我进行更改之前一样长，所有改变的都是数字本身。
这基本上是一个概念证明控制台应用程序，我要改变成一个windows形式的应用程序，我试图确保它背后的数学是正确的。

Due to the amounts of Nocxium, Zydrine and Megacyte used in even titans being negligible in terms of space
(a Titan worth of Nocxium is not even half a JF) and to reduce the amounts of complexity of the problem
as well as only wanting to account for high sec ores as they are the most available in trade hubs and thus most likely to be used,
Nocxium totals will be subtracted if Pyroxeres is needed and will be removed from the total that is
sent back to the user.

乍一看，不确定这是否是唯一的问题，但是您声明
long[] oresTcount = new long[10];
oresTcount[10]++;
oresTcount数组的最大可用索引是9，(从索引0到9的10个元素)，所以，如果你想使用索引10，你需要用
long[] oresTcount = new long[11];
如果您真的从异常中读取堆栈跟踪，您会看到失败行是
oresTCount[10]++;
变量oresTCount被定义为new long[10]，表示其索引包含0& &;9域。
我认为问题出在您使用oresTcount上。它被定义为:
long[] oresTcount = new long[10];
但是你引用了oresTcount[10]:
oresTcount[10]++;
和
Console.WriteLine("Compressed Omber:" + oresTcount[10]);
只能使用oresTcount的当前定义引用索引0-9。
您应该能够查看异常的堆栈跟踪，以验证引起异常的行。
