计划需要太多的内存 [英] Program takes too much memory

问题描述

我使用WPF开发康威的生命游戏的模拟器。

从某些原因，有时程序占用到内存400,000K（当我画很多细胞真快）的。

我怎样才能减少内存使用和/或减少因它的滞后。

细胞结构：

 结构细胞
 {
公众诠释邻居{搞定;设置;} 
公共布尔活着{搞定;组; } 
} 
  

编辑2：
我会尝试解释程序结构：
细胞是包含AutoProperty邻居ofType int类型的结构，AutoProperty的IsAlive ofType布尔

CellGrid是一个封装A级一个二维数组单元。
每次迭代，每个单元的邻居属性被更新，以包含邻居的数量还活着，然后在每个单元的的IsAlive设置为true或false，取决于邻居和以前的IsAlive状态的数量。

MainWindow类有一个类型CellGrid的对象。
这使得电网到屏幕上。

解决方案

这是使用的DrawingContext / DrawingVisual的结果。它实际上是良性的，都应该被垃圾收集系统需要它，但内存使用都可以报警。如果你要，而是画在画布上的形状，那么你可能不会看到这个问题。我碰到的，在过去​​的自定义绘制控件同样的问题。切换到更多的基于矢量的绘图技术（即在画布上的形状）固定内存消耗问题。

I'm using WPF to develop a simulator of Conway's Game of Life.

From some reason, sometimes the program takes up to 400,000K memory (When I draw a lot of cells really fast).

How can I reduce the memory usage and/or reduce the lags caused by it.

Edit 1: Main Window Code: http://pastebin.com/mz0z7tBu

Grid class: http://pastebin.com/ZHX1WBuK

cell struct:

struct Cell
{
    public int Neighbors {get; set;}
    public bool Alive { get; set; }
}

Edit 2: I'll try to explain Program Structure: Cell is a structure that contains AutoProperty neighbors ofType int, and AutoProperty IsAlive ofType bool.

CellGrid is a Class that wraps a 2D array of Cells. Every iteration, each Cell's Neighbors property is updated to contain the number of Neighbors alive, and then each Cell's IsALive is set to true or false, depends on number of neighbors and previous IsAlive state.

The MainWindow class has an object of type CellGrid. It renders the grid to the screen.

        <Setter Property="VerticalContentAlignment" Value="Center" />
        <Setter Property="MaxHeight" Value="32" />
    </Style>
    <Style TargetType="{x:Type MenuItem}" x:Key="ParentMenuItem">
        <Setter Property="Width" Value="46" />
    </Style>
</ResourceDictionary>

解决方案

This is the result of using a DrawingContext/DrawingVisual. It's actually benign and should all be garbage collected as the system needs it, but the memory usage can be alarming. If you were to, instead, draw shapes on a canvas then you would probably not see this problem. I've run into this same issue with custom drawn controls in the past. Switching to more vector-based drawing techniques (i.e., shapes on a canvas) fixed the memory consumption problem.
