Workbook.Close 未在 Excel 插件 C# 中触发 WorkbookBookBeforeClose 事件

Question

在我的 ThisAddins.cs 中有 WorkbookBookBeforeClose 事件，并且在 Ribbon.cs 文件中有一个按钮事件，我写了 workbook.close (true,workbook.fullname,null) 它在处理多个文件时没有触发 WorkbookBookBeforeClose 事件。

调用 workbookBeforeClose 事件有什么要遵循的吗？

以下代码在我这边工作正常：

    public partial class ThisAddIn
    {
        private void ThisAddIn_Startup(object sender, System.EventArgs e)
        {
            this.Application.WorkbookBeforeClose += ApplicationOnWorkbookBeforeClose;
        }

        private void ThisAddIn_Shutdown(object sender, System.EventArgs e)
        {
        }

        // Catch the before close event
        private void ApplicationOnWorkbookBeforeClose(Excel.Workbook wb, ref bool cancel)
        {          
            MessageBox.Show("ApplicationOnWorkbookBeforeClose");
        }

      

        #region VSTO generated code

        /// <summary>
        /// Required method for Designer support - do not modify
        /// the contents of this method with the code editor.
        /// </summary>
        private void InternalStartup()
        {
            this.Startup += new System.EventHandler(ThisAddIn_Startup);
            this.Shutdown += new System.EventHandler(ThisAddIn_Shutdown);
        }

        #endregion
    }
