打开Word文档，除非它具有C#密码 [英] Open Word document, unless it has password with C#

问题描述

我要执行的操作是在Word文档的文件夹中运行，然后使用Tiff打印机将它们转换为.tif文件.问题是，如果我遇到一个带有密码的文档，它应该跳过该文档而不提示您输入密码，而所有这些都应该保留在后台.

The thing i am trying to do is run through folders of word documents and convert them to .tif files using a tiff printer in word. The problem is, if i run into a document, with a password it should skip the document without prompting to ask for password, it should all remain in background.

我可以看到Document类具有HasPassword属性，但是在打开文档之前无法对其进行检查.

I can see that the Document class have a HasPassword property, but it cannot be checked before the document is opened.

word.Documents.OpenNoRepairDialog(@"c:\testfolder\testDocWithPw.docx", ReadOnly: true);

我还尝试给密码设置一个emtpy参数，并尝试捕获一个错误代码.但是我必须按取消"到提示输入密码的提示.

I also tried to give password a emtpy parameter, to and try to catch a errorcode. But i have to press cancel to the prompt asking for password to ever get there.

Application word = new Application();
word.DisplayAlerts = WdAlertLevel.wdAlertsNone;
try
{
    word.Documents.OpenNoRepairDialog(@"c:\testfolder\Doc2.docx", ReadOnly: true, PasswordDocument: "");
    word.ActivePrinter = "TIFF Image Printer 10.0";
    Doc.PrintOut(); //printout untested for now
    Doc.Close(false);
}
catch (System.Runtime.InteropServices.COMException ex)
{
    if (ex.ErrorCode == 0x12345678)
    {
        //skip file and log file name and position for review
    }
}

提前谢谢

只是尝试使用错误的密码来输入密码，而我可以使用错误代码部分，而最好的部分是，当没有密码时，即使您给了密码，它也会打开文件.所以它基本上可以满足我的要求. 在更糟糕的情况下，如果我不应该访问密码不正确的文档，我猜我应该不应该打开文档的某人的密码，则可以检查hasPassword属性.

Just tried to feed the password with wrong password, and i could use the errorcode part, and the best part is that, when there no password it will open the file even if u give it a password. So it basically does what i want. In worse case, that i guess someones password on a document that i shouldn't have opened, i can check on the hasPassword property, if i shouldn't have access to a poorly passworded document.

推荐答案

我自己回答这个问题，所以我没有悬而未决的问题. 解决方法很简单，只要打开一个密码就给一个密码，如果您留下一个空字符串，就和不提任何问题一样.然后可能会捕获到com异常，并且可以处理它，但是我想这样做.

I answer this my self, so i don't have a unanswered question hanging. Solution was simple, just give a password when open one, if you leave a empty string, its the same as not giving a question. Then a com exception could be catched and could handle it however i wanted.

Application word = new Application();
word.DisplayAlerts = WdAlertLevel.wdAlertsNone;
try
{
    word.Documents.OpenNoRepairDialog(@"c:\testfolder\Doc2.docx", ReadOnly: true, PasswordDocument: "RandomButSurelyNotRightPassword");
    word.ActivePrinter = "TIFF Image Printer 10.0";
    Doc.PrintOut(); //printout untested for now
    Doc.Close(false);
}
catch (System.Runtime.InteropServices.COMException ex)
{
    if (ex.ErrorCode == 0x12345678)
    {
        //skip file and log file name and position for review
    }
}
