无法以MS Word读取openXML表

Question

I'm trying to read all the tables from a word file into a list, although for some reason the count is 0 regardless of how many tables are in the file. Here's my code.

public void FindAndReplace(string DocPath)
{
  using (WordprocessingDocument doc = WordprocessingDocument.Open(DocPath, true))
  {
    using (StreamReader reader = new StreamReader(doc.MainDocumentPart.GetStream()))
    {
      //Text titlePlaceholder = doc.MainDocumentPart.Document.Body.Descendants<Text>().Where((x) => x.Text == "Compliance Review By:").First();
      List<Table> tables = doc.MainDocumentPart.Document.Descendants<Table>().ToList();
      System.Console.WriteLine(tables.Count);

tables.Count = 0. What am I doing wrong?

Answer 1

If all you're trying to do is READ the tables, then there's no need to open the document for editing (which is what you're doing currently)

Set the second parameter to false in WordprocessingDocument.Open() to open for reading. This will prevent the error related to opening an entry more than once in Update mode (I assume that's what you're running into anyway).

Solution based on chatter

The real culprit here has to do with using the wrong OpenXml namespace when examining tables in the document. When looking for Descendants of type Table, the passed-in type must be OpenXml. Wordprocessing .Table, NOT OpenXml. Drawing .Table

I don't know what type of object the OpenXml.Drawing.Table is used for. I'll ask about this in a separate question.

Answer 2

You probably are referencing a wrong Table . This should work:

var tables = doc.MainDocumentPart.Document.Descendants<DocumentFormat.OpenXml.Wordprocessing.Table>().ToList();

Answer 3

Anu start had the answer in the comments. The problem was that I was using an incorrect namespace. Instead of using DocumentFormat.OpenXml.Wordprocessing.Table I was using DocumentFormat.OpenXml.Drawing.Table
