我正在Outlook中开发VSTO，它要求MSWord创建一个Word文档，然后将其另存为PDF，然后VSTO退出单词。我正在使用VS2017 Professional和Office365-MSWord版本16。
如果MSWord未打开-下面的代码就像对待。但是，如果打开了MSWord，我会收到一条警告，提示“ Word无法保存文件，因为它已经在其他位置打开了（normal.dotm）” 。现在，我知道这个问题已经被解决了很多次，我已经尝试了所有可以在StackExchange和其他地方找到的解决方案。该问题以前是通过引用this question中的答案来解决的，但是自从Office365最近更新以来，同样的警告又回来了。
下面是我正在使用的代码的子集-所有文件名等均有效。
// start word to create PDF file
Word.Application wordApp = new Word.Application();
Word.Document wrdDoc = new Word.Document();
object saveOption = false;
//Word.WdSaveOptions.wdDoNotSaveChanges;
object oMissing = Type.Missing;
Word.Documents d = wordApp.Documents;
try
{
// set the word app invisible
wordApp.Visible = false;
// open the document with the tmpfilename
wrdDoc = d.Open(FileNameIn, Visible: true);
//set the page size ...
//wrdDoc.PageSetup.PaperSize = Word.WdPaperSize.wdPaperA4;
}
catch (COMException es)
{
throw (es);
}
try
{
//Save/Export our document to a PDF
wrdDoc.ExportAsFixedFormat(OutputFileName: FileNameOut, ExportFormat: Word.WdExportFormat.wdExportFormatPDF,
OpenAfterExport: false, OptimizeFor: Word.WdExportOptimizeFor.wdExportOptimizeForPrint,
Range: Word.WdExportRange.wdExportAllDocument, From: 0, To: 0, Item: Word.WdExportItem.wdExportDocumentContent,
IncludeDocProps: true, KeepIRM: true, CreateBookmarks: Word.WdExportCreateBookmarks.wdExportCreateNoBookmarks,
DocStructureTags: true, BitmapMissingFonts: true, UseISO19005_1: false);
// trick our Word App into thinking that we have been saved
wordApp.NormalTemplate.Saved = true;
}
catch (COMException es)
{
// there is an actual error reporting mechanism here
throw (es);
}
finally
{
try
{
// make our document think its been saved
wrdDoc.Saved = true;
// close our document
wrdDoc.Close(ref saveOption, ref oMissing, ref oMissing);
// trick our Word App into thinking that we have been saved
wordApp.NormalTemplate.Saved = true;
wordApp.Quit(ref saveOption, ref oMissing, ref oMissing);
// release our document object
Marshal.ReleaseComObject(wrdDoc);
// release our documents object
Marshal.ReleaseComObject(d);
// release our application object
Marshal.ReleaseComObject(wordApp);
}
catch (Exception es)
{
// there is an actual error reporting mechanism here
throw (es);
}
finally
{
//
}
}

最近几天，我从错误中学到了很多东西，我在上面寻求了一些帮助。
我了解到，为了正确调试Outlook和MSWord的问题，应该卸载当前正在运行的所有第三方加载项，然后尝试解决问题。在我的特殊情况下，我发现一个名为Nuance Paperport的程序具有将Word文档转换为PDF的加载项，该加载项锁定normal.dotm模板，并且在要求退出代码中的单词时不遵守规则。尽管对某些人来说这可能是微不足道的，但对我来说却是一个宝贵的教训。
下面是将Word文档转换为PDF的代码，这是我目前确定要使用的代码。
/// <summary>
/// A test to see if word is working
/// this function takes a valid word document and converts it to a PDF
/// and takes the user to explorer with the converted file selected
/// </summary>
/// <param name="WordDocIn">a valid path\filename to an existing word document (doc, docx, rtf, htm, mhtml</param>
/// <returns>returns False if there are no errors and the function completed successfully</returns>
private bool WordToPDF(string WordDocIn)
{
// check and make sure our file parameter actually exists
if(!File.Exists(WordDocIn))
{
MessageBox.Show("The file does not exist\n\n" + WordDocIn + "\n\n", "Office Assist: Error()", MessageBoxButtons.OK, MessageBoxIcon.Error);
return true; // true meaning there are errors
}
string tmpFilename = WordDocIn;
// create a temp filename in temp directory
string opFileName = GetTempFilePathWithExtension("pdf");
// set our return value
bool ErrorsPresent = false; // false meaning there are NO errors
// create our word app
Word.Application wordApp = new Word.Application();
// get our documents collection (if any)
Word.Documents d = wordApp.Documents;
// create our new document
Word.Document wrdDoc = new Word.Document();
// create our word options
object saveOption = false;// Word.WdSaveOptions.wdDoNotSaveChanges;
// create our missing object
object oMissing = Type.Missing; ;// Type.Missing;
try
{
// set the word app visisble for the moment sp
// we can see what we're doing
wordApp.Visible = false;
// suppress our alerts
wordApp.DisplayAlerts = Word.WdAlertLevel.wdAlertsNone;
// we dont need any addins - unload all of our addins
// need to open word with no addins loaded ...
wordApp.AddIns.Unload(true); // True to remove the unloaded add-ins from the AddIns collection
// (the names are removed from the Templates and Add-ins dialog box).
// False to leave the unloaded add-ins in the collection.
// open the document with the tmofilename
wrdDoc = d.Open(tmpFilename, Visible: true);
//set the page size ... to A4 (note this will throw an error if the default printer does not produce A4)
wrdDoc.PageSetup.PaperSize = Word.WdPaperSize.wdPaperA4;
//
// export our document to a PDF
//
wrdDoc.ExportAsFixedFormat(OutputFileName: opFileName, ExportFormat: Word.WdExportFormat.wdExportFormatPDF,
OpenAfterExport: false, OptimizeFor: Word.WdExportOptimizeFor.wdExportOptimizeForPrint,
Range: Word.WdExportRange.wdExportAllDocument, From: 0, To: 0, Item: Word.WdExportItem.wdExportDocumentContent,

DocStructureTags: true, BitmapMissingFonts: true, UseISO19005_1: false);
// trick our Word App into thinking that the document has been saved
wrdDoc.Saved = true;
// close our word document
wrdDoc.Close(ref saveOption, ref oMissing, ref oMissing);
// close our documents collection
//d.Close(ref saveOption, ref oMissing, ref oMissing);
foreach (Word.Template template in wordApp.Templates)
{
switch (template.Name.ToLower())
{
case "normal.dotm":
template.Saved = true;
break;
}
}
// quit word
wordApp.Quit(ref saveOption, ref oMissing, ref oMissing);
}
// catch our errors
catch (COMException es)
{
string errcode = "ComException : " + es.Message + "\n\n" + "Show this message to your admin";
MessageBox.Show("Check the default printer has the ability to print A4\nSelect a new printer and try again\n\n" + errcode, "Office Assist: Error()", MessageBoxButtons.OK, MessageBoxIcon.Error);
ErrorsPresent = true;
//throw (es);
}
catch (Exception es)
{
string errcode = "Exception : " + es.Message + " \n\n " + "Show this message to your admin";
MessageBox.Show(errcode, "Office Assist: Error()", MessageBoxButtons.OK, MessageBoxIcon.Error);
ErrorsPresent = true;
//throw (es);
}
finally
{
try
{
// release our objects
Marshal.ReleaseComObject(wrdDoc);
Marshal.ReleaseComObject(d);
Marshal.ReleaseComObject(wordApp);
}
catch (Exception es)
{
string errcode = "Exception : " + es.Message + " \n\n " + "Show this message to your admin";
MessageBox.Show(errcode, "Office Assist: Error()", MessageBoxButtons.OK, MessageBoxIcon.Error);
ErrorsPresent = true;
}
}
// if there are no errors present
// open explorer and select the pdf created
//
if (!ErrorsPresent)
{
// set our switches
string argument = "/select, \"" + opFileName + "\"";
// open explorer and select the file
Process.Start("explorer.exe", argument);
}
return ErrorsPresent;
}
鉴于我花费了很多时间来解决此问题，并且看到了与将Word文档转换为PDF以及规范模板的类似性质或类似问题有关的帖子数量，我认为应该发表评论关于我所学到的知识并发布对我有用的代码，以希望将来对其他人有帮助。
