LINQ到SQL的DataContext温莎IoC的内存泄漏问题 [英] Linq to SQL DataContext Windsor IoC memory leak problem

问题描述

我有使用Castler温莎的IoC。

I have an ASP.NET MVC app that creates a Linq2SQL datacontext on a per-web-request basis using Castler Windsor IoC.

由于某种原因，我不完全理解，每一个新的datacontext创建时间（每个web请求）的内存大约8K被吸收而不是释放 - 这不可避免地会导致内存不足异常。

For some reason that I do not fully understand, every time a new datacontext is created (on every web request) about 8k of memory is taken up and not released - which inevitably causes an OutOfMemory exception.

如果我强迫垃圾收集内存被释放确定。

If I force garbage collection the memory is released OK.

我的DataContext类是非常简单的：

My datacontext class is very simple:

 public class DataContextAccessor : IDataContextAccessor
 {
    private readonly DataContext dataContext;
    public DataContextAccessor(string connectionString)
    {
        dataContext = new DataContext(connectionString);           
    }
    public DataContext DataContext { get { return dataContext; } }
 }

温莎国际奥委会webconfig实例，这看起来像这样：

The Windsor IoC webconfig to instantiate this looks like so:

 <component id="DataContextAccessor"
             service="DomainModel.Repositories.IDataContextAccessor, DomainModel"
             type="DomainModel.Repositories.DataContextAccessor, DomainModel"
             lifestyle="PerWebRequest">       
    <parameters>
      <connectionString>
        ...
      </connectionString>
    </parameters>
  </component>

有谁知道问题是什么，以及如何解决它？

Does anyone know what the problem is, and how to fix it?

推荐答案

L2S的DataContext实现了IDisposable。你的界面也有实现它，并调用DataContext.Dispose（），以便温莎知道有正在资源被布置

L2S DataContext implements IDisposable. Your interface also has to implement it, and call DataContext.Dispose(), so that Windsor knows that there're resources to be disposed.

顺便说一句提防温莎/ IDisposable的问题：
