Today, I will talk to you about how to use OpenXML to operate PPT documents in C#. Many people may not know much about it. In order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.
OpenXML is an official Microsoft open source operation Word, Excel and PPT SDK, developed with C #, using this kind of library can easily operate the three main types of office documents, and do not need to install Office programs.

Using (PresentationDocument presentationDocument = PresentationDocument.Open (_ outfile, true))
{
Try
{
/ / SlideParts is every presentation page in the ppt document
SlideParts _ sdataParts = presentationDocument.PresentationPart.SlideParts
/ / get the first document presentation page
Var _ sdataPart = _ sdataParts.FirstOrDefault ()
/ / find where the text in the demo page contains forecasthour
Var chageText = _ sdataPart.Slide.Descendants () .FirstOrDefault (p = > p.Text.Contains ("forecasthour"))
/ / replace the text with the current date
ChageText.Text = _ dt.ToString ("yyyy-MM-dd HH:mm")
/ / find the list of pictures in the demo page
Var _ imgParts = _ sdataPart.ImageParts
/ / find the picture whose name is image7.png, and replace the file from the outside
ImagePart _ firImgPart = _ imgParts.FirstOrDefault (p = > p.Uri.ToString () .Contains ("image7.png"))
If (_ firImgPart! = null)

/ / replace the picture file
_ firImgPart.FeedData (fs)
}
}
}
Catch (Exception ex1)

}
}
