Adding image in word document

Question

When I add an image to a word document then, when I open word it is showing me an XML error. The file cannot be opened because there is a problem with the content.

See error ->

I took reference from the below link.

Adding image to word document using OpenXML

and from Microsoft site

https://docs.microsoft.com/en-us/office/open-xml/how-to-insert-a-picture-into-a-word-processing-document

My Code is as follows : add Open XML to your project reference.

using DocumentFormat.OpenXml;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Wordprocessing;
using System.IO;
using DW = DocumentFormat.OpenXml.Drawing.Wordprocessing;
using A = DocumentFormat.OpenXml.Drawing;
using PIC = DocumentFormat.OpenXml.Drawing.Pictures;

namespace InsertImageWord

    }

Please help me out of this. Thanks in Advance

Answer 1

your imageparttype has to match the mimetype of your image
