无法捕获WPF窗口Show()抛出的Win32Exception（配额不足）问题求助
我有一个桌面应用，其中包含第三方创建的小型XAML窗口。调用该窗口时会触发System.ComponentModel.Win32Exception导致崩溃，异常信息为**"Not enough quota is available to process this command"**，且仅在打开多个文件后才会触发。
触发异常的代码
触发操作是简单的window.Show()调用，我尝试了多种捕获方式均失败，代码如下：
try { var window = new System.Windows.Window { ResizeMode = ResizeMode.NoResize, Content = new EdgeBarPageView(), WindowStyle = WindowStyle.None }; window.Show(); return new WindowInteropHelper(window).Handle; } //catch (Exception e) //{ // MessageBox.Show(e.Message + "\n" + e.StackTrace, "GetEdgeBarView - Running GC and trying again."); //} catch (Win32Exception ex) when (ex.InnerException is Win32Exception) //catch(System.ComponentModel.Win32Exception e) { MessageBox.Show(ex.Message + "\n" + ex.StackTrace, "GetEdgeBarView - Running GC and trying again."); }
尝试过的捕获方案（均无效）
- 最初添加
Exception捕获分支，无法捕获异常 - 注释掉
Exception分支后单独捕获System.ComponentModel.Win32Exception，依然失败 - 参考代码添加带
when条件的捕获分支，还是无法拦截异常
环境与相关代码说明
- 异常发生时GDI对象计数低，系统内存充足（32GB物理内存+100GB交换空间，已提交内存不足32GB），但应用本身及处理的文件较大
- 第三方XAML控件代码简单：
public partial class EdgeBarPageView : UserControl { public EdgeBarPageView() { InitializeComponent(); } }
