bing地图控件的内存问题 [英] Memory issue for bing map control

问题描述

In my application the memory usage becomes high when navigating from a page having map control.Is there any way to reduce memory usage for bing map control?

推荐答案

我相信这样做的原因是在您导航回上一页后会保留对 Map 控件的引用.除了释放任何引用，我发现使用 SetMode 方法也有助于释放引用:-

I believe the reason for this is that a reference to the Map control is maintained after you navigate back to the previous page. In addition to freeing any references, I found that using the SetMode method also helps free up the references :-

map1.SetMode(new NullMode(), false);

我想我使用以下论坛帖子作为参考(前一段时间):-

I think I used the following forum post as a reference (it was a while ago) :-

就我而言，我不得不做一些额外的清理工作，并更改与使用触发器和取消注册 MVVM Light Messenger 相关的代码结构.

In my case I had to do some additional cleanup and change to code structure with relation to using triggers and unregistring the MVVM Light Messenger.
