在WPF C＃内存泄漏 [英] Memory leaks in wpf C#

问题描述

我开发一个WPF MVVM（在v3.5版本）的应用程序使用GalaSoft.MvvmLight套件和WPF工具包的DataGrid 和的DatePicker 。但是我每一次我在主窗口加载用户控件面临着大量的内存泄漏的应用程序。我想获得通过赛特内存分析器确切的问题，但我有一些严肃的问题：

I am developing a WPF MVVM (in v3.5) application using GalaSoft.MvvmLight suite and WPF Toolkit for DataGrid and DatePicker. However I am facing lots of memory leaks in the application every time I load a UserControl in MainWindow. I am trying to get the exact issue via Scitech Memory profiler, though I have some serious questions :

1. 如何解开/解除绑定的 RelayCommand 从事件在虚拟机？
2. mscorlib程序和presentationFramework也消耗大量内存，其中大部分是字符串。我不知道他们是从哪里来的。

1. How to unhook/unbind the RelayCommand from the Event in VM?
2. mscorlib and PresentationFramework are also consuming lots of memory and most of them are strings. I don't know where they are coming from.

请帮忙。
