最大阵列可能 [英] largest array possible

问题描述

我创建了一个7维数组[11,11,11,11,11,11,11]，它有19.5

百万元素。


当我尝试创建8维数组时，我越界系统

异常。有没有人知道这个限制是由于我的电脑中的内存量是多少？或者是c＃语言的限制？


感谢

嗨tony，


我不认为.net有这样的限制。

我会说这是一个记忆问题。

实际上，我猜有一个限制，因为长度属性限制了

。在1.0版本的框架中，长度

属性是一个32位整数，因此，你被限制为两个元素bbb左右。


使用1.1版本的框架，你有LongLength属性，

暴露64位整数的长度，这意味着你有一个上层

限制为9,223,372,036,854,775,808元素（不用说，很多）。


然而，你遇到的，如Miha所说，可能是因为

的内存约束。对于原始海报，你真的需要在阵列中有很多元素吗？你想做什么？取决于元素的类型，单个内存对于这样的阵列可能在性能方面受到限制。


希望这会有所帮助。

i have created a 7-dimensional array [11,11,11,11,11,11,11] which has 19.5
million elements.

when i try to create 8-dimensional array i get out of bounds system
exception. does anyone know if this limitation is due to amount of memory
in my pc or a limiation of c# language?

thanks

Hi tony,

I don''t think that .net has such limitations.
I would say that it is a memory issue.

Actually, I would guess there is a limit because of the limitation of
the Length propery. In the 1.0 version of the framework, the Length
property was a 32 bit integer, and because of that, you were limited to two
billion or so elements.

With the 1.1 version of the framework, you have the LongLength property,
which exposes the length in a 64 bit integer, which means you have an upper
limit of 9,223,372,036,854,775,808 elements (needless to say, a lot).

However, what you are running into, like Miha said, is probably because
of a memory constraint. To the original poster, do you really need to have
that many elements in the array? What are you trying to do? Depending on
the type of your elements, the memory alone for such an array could be
restrictive in terms of performance.

Hope this helps.
