打开XML -合并(连接)Word文档

Question

我有一个包含多个。docx文档的文件夹，我想创建一个新文档，将它们按字母顺序合并在一起。

我使用的代码是合并他们使用AltChunks -但顺序是错误的。

代替:

"a, b, c, d, e" 

I am getting

"a, e, d, c, b."  

似乎很清楚，所有的插入都发生在同一位置，我无法获得插入正确(我总是在第一个文档之后插入-而我想在最后一个文档之后插入)

代码如下:

private void GenerateMergedDoc(string directoryPathToUse, string outputFolder)
{
string altChunkIdBase = "acID";
int altChunkCounter = 1;
string altChunkId = altChunkIdBase + altChunkCounter.ToString();
MainDocumentPart wdDocTargetMainPart = null;
DocumentFormat.OpenXml.Wordprocessing.Document docTarget = null;
AlternativeFormatImportPartType afType;
AlternativeFormatImportPart chunk = null;
AltChunk ac = null;
System.IO.DirectoryInfo di = new System.IO.DirectoryInfo(directoryPathToUse);
IEnumerable<System.IO.FileInfo> docFiles = di.EnumerateFiles();
List<string> filenames = new List<string>();
foreach (var fileInfo in docFiles)
{
filenames.Add(fileInfo.FullName);
}
filenames.Sort();

using (WordprocessingDocument wdPkgTarget = WordprocessingDocument.CreateFromTemplate(filenames[0], true))
{
wdDocTargetMainPart = wdPkgTarget.MainDocumentPart;
if (wdDocTargetMainPart == null)
{
wdDocTargetMainPart = wdPkgTarget.AddMainDocumentPart();
DocumentFormat.OpenXml.Wordprocessing.Document wdDoc = new DocumentFormat.OpenXml.Wordprocessing.Document(
new Body(
new DocumentFormat.OpenXml.Wordprocessing.Paragraph(
new Run(new Text() { Text = "First Para" })),
new DocumentFormat.OpenXml.Wordprocessing.Paragraph(new Run(new Text() { Text = "Second para" })),
new SectionProperties(
new SectionType() { Val = SectionMarkValues.NextPage },
new PageSize() { Code = 9 },
new PageMargin() { Gutter = 0, Bottom = 1134, Top = 1134, Left = 1318, Right = 1318, Footer = 709, Header = 709 },
new Columns() { Space = "708" },
new TitlePage())));
wdDocTargetMainPart.Document = wdDoc;
}
docTarget = wdDocTargetMainPart.Document;
SectionProperties secPropLast = docTarget.Body.Descendants<SectionProperties>().Last();
SectionProperties secPropNew = (SectionProperties)secPropLast.CloneNode(true);
//A section break must be in a ParagraphProperty
DocumentFormat.OpenXml.Wordprocessing.Paragraph lastParaTarget = (DocumentFormat.OpenXml.Wordprocessing.Paragraph)docTarget.Body.Descendants<DocumentFormat.OpenXml.Wordprocessing.Paragraph>().Last();
ParagraphProperties paraPropTarget = lastParaTarget.ParagraphProperties;
if (paraPropTarget == null)
{
paraPropTarget = new ParagraphProperties();
}
paraPropTarget.Append(secPropNew);
Run paraRun = lastParaTarget.Descendants<Run>().FirstOrDefault();
//lastParaTarget.InsertBefore(paraPropTarget, paraRun);
lastParaTarget.InsertAt(paraPropTarget, 0);
//Process the individual files in the source folder.
//Note that this process will permanently change the files by adding a section break.
for (int i = 1; i < filenames.Count; i++)
{                    
using (WordprocessingDocument pkgSourceDoc = WordprocessingDocument.Open(filenames[i], true))
{
IEnumerable<HeaderPart> partsHeader = pkgSourceDoc.MainDocumentPart.GetPartsOfType<HeaderPart>();
IEnumerable<FooterPart> partsFooter = pkgSourceDoc.MainDocumentPart.GetPartsOfType<FooterPart>();
//If the source document has headers or footers we want to retain them.
//This requires inserting a section break at the end of the document.
if (partsHeader.Count() > 0 || partsFooter.Count() > 0)
{
Body sourceBody = pkgSourceDoc.MainDocumentPart.Document.Body;
SectionProperties docSectionBreak = sourceBody.Descendants<SectionProperties>().Last();
SectionProperties copySectionBreak = (SectionProperties)docSectionBreak.CloneNode(true);
DocumentFormat.OpenXml.Wordprocessing.Paragraph lastpara = sourceBody.Descendants<DocumentFormat.OpenXml.Wordprocessing.Paragraph>().Last();
ParagraphProperties paraProps = lastpara.ParagraphProperties;
if (paraProps == null)
{
paraProps = new ParagraphProperties();
lastpara.Append(paraProps);
}
paraProps.Append(copySectionBreak);
}
pkgSourceDoc.MainDocumentPart.Document.Save();
}
//Insert the source file into the target file using AltChunk
afType = AlternativeFormatImportPartType.WordprocessingML;
chunk = wdDocTargetMainPart.AddAlternativeFormatImportPart(afType, altChunkId);
System.IO.FileStream fsSourceDocument = new System.IO.FileStream(filenames[i], System.IO.FileMode.Open);
chunk.FeedData(fsSourceDocument);
//Create the chunk
ac = new AltChunk();
//Link it to the part
ac.Id = altChunkId;
docTarget.Body.InsertAfter(ac, docTarget.Body.Descendants<DocumentFormat.OpenXml.Wordprocessing.Paragraph>().Last());
docTarget.Save();
altChunkCounter++;
altChunkId = altChunkIdBase + altChunkCounter;
chunk = null;
ac = null;
}
string volText = String.Empty;
if (volumeToCreate.VolumeNumber > 1)
{
volText = "_Vol_" + volumeToCreate.VolumeNumber;
}
string categoryText = String.Empty;
if (volumeToCreate.Prefix.Contains("SDS"))
{
categoryText = "-" + volumeToCreate.Category;
}
newMergeFileName = outputFolder + volumeToCreate.Prefix + "-Merged-V-V" + categoryText + volText + ".docx";

wdPkgTarget.SaveAs(newMergeFileName);
}
}

如果在第一个文档之后追加内容的假设是正确的，则只需更改插入顺序

for (int i = filenames.Count-1; i > 0; i--)
{
Foo();
}   

然后将e, d, c和b加到a，得到最终结果a,b,c,d,e。这可能不是你想要的解决方案，但它会解决你的问题。
