Insert BookmarkEnd into Section.ChildEntities

[Motunrayo Ogunyinka]

Hi,

I need to delete content between two paragraphs in a word document. I can Identify the paragraphs and have inserted the bookmark start before the first paragraph.

If the second paragraph is in the same seciton as the first, then I want to insert the bookmarkend before the second paragraph. If not then I want to insert the bookmarkend as the last item in the section. My aim is to delete the first paragraph and everything following it until (but excluding the second paragraph).

I tried the following:
int stopEntityIndex = -1;
try
{
stopEntityIndex = section.ChildEntities.IndexOf(secondParagraph);
}
catch(ArgumentOutOfRangeException)
{

}

if (stopEntityIndex == -1)
{
stopEntityIndex = section.ChildEntities.Count - 1;
}

BookmarkEnd end = new BookmarkEnd(outDoc,"bkmark");
section.ChildEntities.Insert(stopEntityIndex , end as Entity);

My problem is that I get a System.InvalidOperationException when I try to insert saying {"Cannot insert an object to SectionChildEntities collection."}
