检测受密码保护的单词文件 [英] Detect password protected word file

问题描述

我正在使用"netoffice"库从Word文件中提取文本.这应该是自动化过程.

I am using "netoffice" library for extracting the text from word files. This should be automated process.

但是，当Word文件受密码保护时，会显示警报窗口，因此用户需要输入密码.由于这是自动过程，因此用户无需输入密码，程序将在此处停止.

However, when the word file is password protected, the alert windows is shown so the user needs to enter the password. Because this is automated process, the user does not enters the password, and the program stops here.

如何检测单词文件是否受到"netoffice"的密码保护，并且如果无法实现，如何禁用警报窗口?

How can I detect if the word file is password protected with "netoffice", and if this is not possible, how can I disable the alert windows from showing up?

我尝试将DisplayAlerts设置为WdAlertLevel.wdAlertsNone，但是它不起作用.

I tried setting DisplayAlerts to WdAlertLevel.wdAlertsNone, but it isn't working.

以下代码段将帮助您跳过受密码保护的文件:

The following piece of code will help you skip password-protected files:

        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();
        }
