碰撞最小化窗口＆amp;关闭文件COM AddIn

Question

我尝试最小化并关闭DocumentBeforeClose事件方法中的文档。但如果我这样做，那么这个词就有可能崩溃。并非每次都可重现。

我构建了一个非常简化的插件版本。它只包含事件的注册和事件方法本身：

public void OnConnection(object application, Extensibility.ext_ConnectMode connectMode, object addInInst, ref System.Array custom)
{
      //Apply Application
      m_ApplicationObject = (Microsoft.Office.Interop.Word.Application)application;

      //Register event
      m_ApplicationObject.DocumentBeforeClose += new Microsoft.Office.Interop.Word.ApplicationEvents4_DocumentBeforeCloseEventHandler(m_ApplicationObject_DocumentBeforeClose);                    
}

private void m_ApplicationObject_DocumentBeforeClose(Microsoft.Office.Interop.Word.Document Doc, ref bool cancel)
{
     //Close Document. If you do so, the Word-Window will stay open! WINWORD.EXE will not exit!
     object doNotSaveChanges = MSword.WdSaveOptions.wdDoNotSaveChanges;
     object missing = System.Reflection.Missing.Value;                
     Doc.Close(ref doNotSaveChanges, ref missing, ref missing);

     //Minimize Word-Window.         
     m_ApplicationObject.WindowState = Microsoft.Office.Interop.Word.WdWindowState.wdWindowStateMinimize;
}

崩溃出现在Word 2016上。我无法测试旧版本。

如何重现： 打开随机word文档。点击＆＃39; X＆＃39;关闭文件将结束，单词将最小化。恢复单词并打开随机文档，点击＆＃39; X＆＃39;关闭...重复2-5次，然后发生崩溃。
