[英]Can't get the pages count from a word document with OpenXml
I use the OpenXML SDK v2.11.3 with .net core 3.1 and when I try to get the total pages count from a word document sometimes it returns a null value.我将 OpenXML SDK v2.11.3 与 .net 核心 3.1 一起使用,当我尝试从 word 文档获取总页数时,有时它会返回 null 值。
using (var document = WordprocessingDocument.Open(memoryStream, true))
{
var pages = Convert.ToInt32(document.ExtendedFilePropertiesPart.Properties.Pages.Text);
}
System.NullReferenceException: 'Object reference not set to an instance of an object.'
System.NullReferenceException:“对象引用未设置为 object 的实例。” DocumentFormat.OpenXml.ExtendedProperties.Properties.Pages.get returned null.
DocumentFormat.OpenXml.ExtendedProperties.Properties.Pages.get 返回 null。
What is the best way to get the total pages count from a docx file?从 docx 文件中获取总页数的最佳方法是什么?
Since自从
you cannot necessarily obtain a page count from an arbitrary DOCX file.您不一定能从任意 DOCX 文件中获取页数。
