我正在為 Visual Studio 2017 開發一個擴展，其中包含自定義“toolwindow”。此“工具窗口”包含WPF control訂閱view model了Workspace.WorkspaceChanged和EnvDTE.DTE.Events.WindowEvents.WindowActivated事件。我知道當用戶關閉“toolwindow”時，它實際上并沒有被破壞，而是“隱藏”了。但是，它仍然對我的事件做出反應。所以，我想知道兩個問題的答案：如何檢查工具窗口是否被隱藏？我可以“關閉”工具窗口以便將其銷毀嗎？編輯：創建工具窗口的代碼：protected virtual TWindow OpenToolWindow(){ ThreadHelper.ThrowIfNotOnUIThread(); // Get the instance number 0 of this tool window. This window is single instance so this instance // is actually the only one. // The last flag is set to true so that if the tool window does not exists it will be created. ToolWindowPane window = Package.FindToolWindow(typeof(TWindow), id: 0, create: true); if (window?.Frame == null) { throw new NotSupportedException("Cannot create tool window"); } IVsWindowFrame windowFrame = (IVsWindowFrame)window.Frame; Microsoft.VisualStudio.ErrorHandler.ThrowOnFailure(windowFrame.Show()); return window as TWindow;}

要檢測工具窗口何時關閉，您可以從IVsWindowFrameNotify3繼承它并在 OnShow 方法中檢查 fShow == (int) __FRAMESHOW.FRAMESHOW_WinClosed。

只是為了添加到@Sergey Vlasov 的回答 - 我發現了第二種方法，如果窗口被隱藏/顯示，則會收到通知。這是我的 WPF 控件視圖模型中的代碼。
EnvDTE.DTE dte = MyVSPackage.Instance.GetService<EnvDTE.DTE>();
// _visibilityEvents is a private field.
// There is a recommendation to store VS events objects in a field
// to prevent them from being GCed
_visibilityEvents = (dte?.Events as EnvDTE80.Events2)?.WindowVisibilityEvents;
if (_visibilityEvents != null)
{
_visibilityEvents.WindowShowing += VisibilityEvents_WindowShowing;
_visibilityEvents.WindowHiding += VisibilityEvents_WindowHiding;
}
