OpenXML创建Word文档总是损坏C＃

Question

我正在研究一个旧的WebForms应用程序，并且正在尝试通过其中一个页面中的C＃中的openxml创建Word文档。我正在尝试阅读来自SQL的数据以填充一张表格，我将在Word文档中创建的表格，以按照 http://www.ludovicperrichon.com/create-a-word-document-with-popenxml-and-and-c/

但是，每次我运行该代码会生成一个文档，该文档已损坏了一个文档并显示以下消息：

我看不到问题是什么，我一直在尝试找到解决方案的类似问题，但我只能找到提到流的问题，但这似乎只有在阅读现有文档以编辑不创建新文档时才是。

我的示例代码在下面（不包括加载数据的数据表DT，因为该元素可以正常工作）。

                var header = "";

                using (var stream = new MemoryStream())
                {
                    using (var wordDoc = WordprocessingDocument.Create(stream, WordprocessingDocumentType.Document))
                    {
                        // Add a main document part.
                        MainDocumentPart mainPart = wordDoc.AddMainDocumentPart();

                        // Create the document structure and add some text.
                        mainPart.Document = new Document();
                        Body docBody = new Body();
                        mainPart.Document.Body = docBody;

                        // Load study plan and build word table to hold data
                        // Create an empty table.

Answer 1

您正在使用错误的名称空间中的表格。而不是

var table = new DocumentFormat.OpenXml.Drawing.Table();

使用

var table = new DocumentFormat.OpenXml.Wordprocessing.Table();

此其他表元素（单元格等）而不是使用它。

我建议使用 openxmlsdk 。如果您最终得到一个无效的文件，它将向您显示它出了什么问题。
