Question

I am using the following code:

var images = from pic in slidePart.Slide.Descendants<DocumentFormat.OpenXml.Presentation.Picture>()
             select pic;

foreach (var image in images)
       image.Remove();

The problem is with the loop which executing only once and images contain multiple objects. How can I call image.Remove on all objects.

Answer 1

Try this:

slidePart
    .Slide
    .Descendants<DocumentFormat.OpenXml.Presentation.Picture>()
    .ToList()
    .ForEach(pic => pic.Remove());

Why the .ToList() call? Because you need to ensure that you don't modify the collection you are iterating over.
