使用OpenXml-sdk和C＃来访问Word文件的当前上下文中不存在名称“ c”

问题描述

我正在使用c＃并在服务器上上传后打开xml sdk 2.0来访问Word文件。

我想根据给定的文本检索章节和段落。

这些章插入在表chapter

中

各章和各段插入在表章subheading

中

使用System.Linq可以找到章节Contains Chapter

foreach (Paragraph c in wordDoc.MainDocumentPart.Document.Body.Descendants<Paragraph>().Where<Paragraph>(c => c.InnerText.Contains("Chapter")))

和副标题Starts With "- "

foreach (Paragraph p in wordDoc.MainDocumentPart.Document.Body.Descendants<Paragraph>().Where<Paragraph>(p => p.InnerText.StartsWith("- ")))

但是在进行Visual Studio调试时出现此阻止错误

CS0103: The name 'c' does not exist in the current context

请帮助我
