有谁知道什么会导致 WPF 应用程序出现以下异常？在 Windows 7 x64 上部署后开始发生。应用程序正在使用 .NET 3.5，并且没有导致此问题的特定操作，并且应用程序运行的时间长度是随机的。

我至少找到了导致此问题的 1 个原因。如果将 DataGrid 放入像 StackPanel 这样允许子控件无限调整大小的容器中，那么当您绑定一个大列表（对我来说是 17k 行）时，您会得到一个 OutOfMemoryException。

如果将 DataGrid 放置在像 Grid 这样的固定高度容器中，那么它可以正常工作。

具有讽刺意味的是，我通过试用 DevExpress WPF 库发现了这一点。在这种情况下，他们的网格实际上引发了带有以下文本的异常。

DevExpress.Xpf.Grid.v13.2.Core.dll 中出现“DevExpress.Xpf.Grid.InfiniteGridSizeException”类型的第一次机会异常附加信息：默认情况下，不允许无限网格高度，因为将呈现所有网格行因此网格将非常缓慢地工作。要解决此问题，您应该将网格放入一个容器中，该容器将为网格提供有限的高度，或者您应该手动指定网格的高度或 MaxHeight。请注意，您也可以通过将 GridControl.AllowInfiniteGridSize 静态属性设置为 True 来避免此异常，但在这种情况下，网格将运行缓慢。

一旦我看到这一点，便士就掉了，然后我可以复制并使用 Microsoft DataGrid 修复原始行为。
