VSTO 禁止EXCEL工作表中的右击菜单

    private void ThisWorkbook_Startup(object sender, System.EventArgs e)
    {
        this.ActivateEvent += new Microsoft.Office.Interop.Excel.WorkbookEvents_ActivateEventHandler(ThisWorkbook_ActivateEvent);
        this.SheetActivate += new Microsoft.Office.Interop.Excel.WorkbookEvents_SheetActivateEventHandler(ThisWorkbook_SheetActivate);
    }

    void ThisWorkbook_ActivateEvent()
    {
        Excel.Worksheet sh = ActiveSheet as Excel.Worksheet;
        sh.BeforeRightClick += new Microsoft.Office.Interop.Excel.DocEvents_BeforeRightClickEventHandler(sh_BeforeRightClick);
    }

    void ThisWorkbook_SheetActivate(object Sh)
    {
        Excel.Worksheet sh = ActiveSheet as Excel.Worksheet;
        sh.BeforeRightClick += new Microsoft.Office.Interop.Excel.DocEvents_BeforeRightClickEventHandler(sh_BeforeRightClick);
    }

    void sh_BeforeRightClick(Microsoft.Office.Interop.Excel.Range Target, ref bool Cancel)
    {
        Cancel = true;
    }

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

可能有人会问，除了ThisWorkbook_SheetActivate事件，为什么还要加上一个ThisWorkbook_ActivateEvent事件？

这是因为，打开表的时候，当前表并不会激发ThisWorkbook_SheetActivate事件，所以还需要加上工作簿的激活事件。
