内存超出范围异常 [英] Memory out of range exception

问题描述

在我的应用程序中，我使用非常大的点列表，即

Hi ,
In my application i am using very big lists of points i.e.

List<point> Lst=new List<point>(1008000);

我创建了25个这样的大名单。但遗憾的是CLR抛出了内存异常。

请让我知道如何处理这个问题。

我尝试了什么：



我已经用Google搜索并发现编译为x64解决了这个问题，但我不想将应用程序更改为x64。有没有其他方法来处理内存超出范围问题。

I am creating 25 such big lists. But unfortunately CLR throws out of memory exception.
Please let me know how i can handle this issue.

What I have tried:

I already googled and found that compiling as x64 solves the issue, but i do not want to change application to x64. Is there any other way to handle memory out of range issue.

推荐答案

在x86机器（32位）上，内存总共限制为4gb，其中操作系统占用1GB理论上3gb用于应用程序，但实际上你只限于1.8gb-2.5gb，具体取决于你的硬件。



如果要强烈重新考虑在内存中保留大量数据，除非那里这是一个很好的理由，阻塞/分块数据在大多数情况下效率更高，你不会受到硬件限制。



看看Key / Value数据存储，甚至是为处理数据而设计的关系数据库。

On x86 machines (32bit) the memory is limited to 4gb total of which the OS takes 1gb which leaves theoretically 3gb for apps but practically you are limited to 1.8gb-2.5gb depending on your hardware.

If should strongly rethink keeping a lot of data in memory unless there is a very good reason for it, blocking/chunking data is much more efficient in most cases and you will not be limited by your hardware.

Look at Key/Value data stores, or even relational databases which were designed for handling data.
