使用Response.Write（）时内存泄漏 [英] Memory leak when using Response.Write()

问题描述

大家好。


我有一个网络应用程序，我使用框架。我的主框架由

三个内框组成。


当在框架A中按下某个按钮时，框架B的内容为

重新加载。我正在使用这样的代码来实现这个目标：

string strRedirect;

strRedirect ="< script language =''Javascript''>" ;;

strRedirect + =" parent.body.location.href =''WFSearchResult.aspx'';" ;

strRedirect + ="< / script>" ;;

Response.Write（strRedirect）;


I注意到我的应用程序中存在内存泄漏。我使用.NET内存

Profiler来跟踪它们，我发现在加载某些帧的内容时，内存的使用会增加

- 我在PageLoad上有一个断点
方法在所有帧中，但使用内存后增加了

Response.Write代码和之前的PageLoad框架。


所以我认为框架的旧内容未发布，这是内存泄漏的原因。

有没有人知道一些方法来防止内存泄漏情况我

描述？也许有一些方法我可以到旧框架和

处理它？<​​br />

提前谢谢，

Hi all.

I have a web app, in which I use frames. My main frameset consists of
three inner frames.

When some button is pressed in frame A, then content of frame B is
reloaded. I am using such code to achieve this:
string strRedirect;
strRedirect = "<script language=''Javascript''>";
strRedirect += "parent.body.location.href=''WFSearchResult.aspx'';" ;
strRedirect += "</script>";
Response.Write(strRedirect);

I noticed that there are memory leaks in my app. I used .NET Memory
Profiler to trace them and I discovered that usage of memory increases
when content of some frame is loaded - I had a breakpoint on PageLoad
method in all frames, but usage of memory increasead after
Response.Write code and before PageLoad of frame.

So I think that old content of frame is not released and that is the
cause of memory leak.

Does anybody know some method to prevent memory leaks in situation I
described? Maybe there is some way I can get to the old frame and
dispose it?

Thanks in advance,
Piotrek

推荐答案

我真的没有看到代码中存在内存泄漏的问题

你已经表明了它使用了一些内存，但是当发生

垃圾收集时它应该全部返回。


您可以将创建的字符串数量从三个减少到一个：


string strRedirect;

strRedirect ="< script language =''Javascript''>" +

" parent.body.location.href =''WFSearchResult.asp x'';" +

"< / script>" ;;

Response.Write（strRedirect）;


这减少了金额代码使用的内存。不过它确实不会产生那么大的差别。


Piotrek写道：

I don''t really see how there could be a memory leak from the code that
you''ve shown. It uses some memory, but it should all be returned when a
garbage collection occurs.

You can reduce the number of strings created from three to one:

string strRedirect;
strRedirect = "<script language=''Javascript''>" +
"parent.body.location.href=''WFSearchResult.asp x'';" +
"</script>";
Response.Write(strRedirect);

This reduces the amount of memory the code uses. Not that it really
should make that much of a difference, though.

Piotrek，

我认为你假设一个带有框架的ASP.NET应用程序，它严格地是客户端浏览器处理的构造，是
，是谬误。所有

ASP.NET页面都知道它正在被请求，它不关心它是否被加载到框架中。与否 - 它仍然完全相同的工作。

Piotrek,
I think your assumption that an ASP.NET application with frames, which are
strictly a client-side browser-handled construct, is fallacious. All the
ASP.NET page knows is that it is being reqeusted, it cares not whether it is
being loaded "into a frame" or not - it still does exactly the same work.
