OpenXML 创建 Word 文档总是损坏 C#

Question

我正在开发一个旧的 webforms 应用程序，我正在尝试通过其中一个页面中的 C# 中的 OpenXml 创建一个 word 文档。我正在尝试从 SQL 中读取数据以填充 table 我将按照 http://www.ludovicperrichon.com/create-a-word-document-with-openxml-and-c/

中的示例在 word 文档中创建

但是，每次我运行代码都会生成 Word 报告已损坏的文档并显示以下消息：

我看不出问题是什么，我一直在尝试寻找类似问题的解决方案，但我只能找到关于流问题的提及，但这似乎只有在阅读现有文档进行编辑时才会出现没有创建一个新的。

我的示例代码如下（不包括加载数据的 DataTable dt，因为该元素工作正常）。

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

                        // Create a TableProperties object and specify its border information.

Answer 1

您正在使用来自错误命名空间的 table 元素。而不是

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

使用

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

这也适用于所有其他 table 元素（单元格等）。

我推荐使用 OpenXMLSDK。如果您最终得到一个无效文件，它会告诉您它有什么问题。
