how to insert bookmark in word using c#/VB.NET

Question

I am trying to add bookmarks in word document using C# but it doesn't work and I can't find any help neither in msdn documentation nor on internet. Here is how I am trying to do.

I am reading word documents and then search a keyword in that document and then I convert that text to a hyperlink and that works great. Now, I want to create that text to a bookmark instead of hyperlink. I am doing all this in C#

Answer 1

Dim _wordApp As ApplicationClass
Dim _doc As Document
Dim pos, len As Integer
Dim reg As Regex
Dim bookmarkName As String
Dim rng As Object
Dim search As String = "Some Text to search"

Dim nullobj As Object = System.Reflection.Missing.Value
Dim isReadOnly As Object = False
_wordApp = New ApplicationClass()

'open the word document
_doc = _wordApp.Documents.Open(fileName, isReadOnly, nullobj, nullobj, nullobj, _
     nullobj, nullobj, nullobj, nullobj, nullobj, nullobj, _
     nullobj, nullobj, nullobj, nullobj, nullobj)

    _wordApp.Visible = False


' keyword that you want to search
reg = New Regex(search)
' find the text in word file
Dim m As Match = reg.Match(_doc.Range.Text, 0)
pos = m.Index

' start is the starting position of the token in the content...
len = search.Length
' select the text
rng = _doc.Range(pos, len + pos)

bookmarkName = "MyBookmarkName"
_doc.Bookmarks.Add(bookmarkName, rng)

You need to get to grips with the Open XML SDK. It's not well documented...

I posted some significant time ago about inserting images into Word documents. Not the same thing at all, but you never know, you might find some pointers to get you started...
