如何使用Microsoft.Office.Interop打开文件时禁用弹出窗口

Microsoft.Office.Interop.[OFFICE_APP].Application app = new Microsoft.Office.Interop.[OFFICE_APP].Application();
app.DisplayAlerts = false;

Application wordApp = new Application()
{
    Visible = false,
    AutomationSecurity = Microsoft.Office.Core.MsoAutomationSecurity.msoAutomationSecurityForceDisable
};

Microsoft.Office.Interop.Word.Application appWord = new 
Microsoft.Office.Interop.Word.Application();

appWord.DisplayAlerts = Microsoft.Office.Interop.Word.WdAlertLevel.wdAlertsNone;

app.DisplayAlerts = false

var app = new Application();
app.DisplayAlerts = false;
var workbook = app.Workbooks.Open(filePath, "fakePassword"); // Bypasses dialog, throws error
