我正在使用" netoffice"用于从word文件中提取文本的库。这应该是自动化过程。
但是,当word文件受密码保护时,会显示警告窗口,因此用户需要输入密码。由于这是自动过程,因此用户不输入密码,程序将在此处停止。
如何使用" netoffice"检测word文件是否受密码保护,如果无法做到这一点,如何禁用警报窗口显示?
我尝试将DisplayAlerts设置为WdAlertLevel.wdAlertsNone,但它不起作用。

以下代码将帮助您跳过受密码保护的文件:
int iFilesWithPassword = 0;
Factory.Initialize();
Application wordApplication = new NetOffice.WordApi.Application();
try
{
// Attempt to open existing document. If document is not password protected then
// passwordDocument parameter is simply ignored. If document is password protected
// then an error is thrown and caught by the catch clause the follows, unless
// password is equal to "#$nonsense@!"!
Document newDocument = wordApplication.Documents.Open(@"C:\Users\Giorgos\Desktop\myNextFile.doc",
confirmConversions: false,
addToRecentFiles: false,
readOnly: false,
passwordDocument: "#$nonsense@!");
// read text of document
string text = newDocument.Content.Text;
}
catch(Exception e)
{
Exception inner = e.InnerException;
if (inner != null && inner.InnerException != null)
{
inner = inner.InnerException;
string sErrorMessage = inner.Message;
if (sErrorMessage.Contains("The password is incorrect."))
{
iFilesWithPassword++;
}
}
}
finally
{
// close word and dispose reference
wordApplication.Quit();
wordApplication.Dispose();
}
