WPF System.OutOfMemoryException System.Windows.Automation.Peers.AutomationPeer.UpdateSubtree

问题描述

我已经在.NET Framework 4.5.1上构建了WPF桌面应用程序.它通常"可以正常工作，但是在某些计算机上，在运行时将显示WPF数据网格时出现System.OutOfMemoryException.

I've built a WPF desktop application on .NET framework 4.5.1. It "usually" works fine, but, on certain machines, at runtime, a System.OutOfMemoryException when a WPF datagrid is going to be shown.

堆栈跟踪报告:

An error of type System.OutOfMemoryException occurred.

非工作计算机为32位，Windows 7、2 GB RAM，.NET Framework 4.5.1..

Non-working machines are 32 bit, Windows 7, 2 GB of RAM, .NET framework 4.5.1.

我必须说，数据网格仅显示几行.我一直在网上寻找类似的错误，但是找不到任何合适的解决方案.

I must say that the datagrid only displays few rows.I've been looking for similar errors on the web, but I couldn't find any suitable solution.

有什么建议吗?

谢谢！
