Replace Text Search String in Word Document with Image | C# .NET

Hello Awais Hafeez,

I am facing same issue, should i send my code or do you have generic code to resolve issue.

Thanks & Regards,
Manjunath.

@srisaimanjunath,

The following C# code of Aspose.Words for .NET API will replace a keyword in Word DOCX document with a PNG Image:

Document doc = new Document("C:\\Temp\\Word.docx");

FindReplaceOptions opts = new FindReplaceOptions();
opts.Direction = FindReplaceDirection.Backward;
opts.ReplacingCallback = new ReplaceEvaluator();

doc.Range.Replace("replace me", "", opts);

doc.Save("C:\\Temp\\21.5.docx");

private class ReplaceEvaluator : IReplacingCallback
{
    ReplaceAction IReplacingCallback.Replacing(ReplacingArgs e)
    {
        // This is a Run node that contains either the beginning or the complete match.
        Node currentNode = e.MatchNode;

        // The first (and may be the only) run can contain text before the match,
        // in this case it is necessary to split the run.
        if (e.MatchOffset > 0)
            currentNode = SplitRun((Run)currentNode, e.MatchOffset);

        // This array is used to store all nodes of the match for further removing.
        ArrayList runs = new ArrayList();

        // Find all runs that contain parts of the match string.
        int remainingLength = e.Match.Value.Length;
        while (
            (remainingLength > 0) &&
            (currentNode != null) &&
            (currentNode.GetText().Length <= remainingLength))
        {
            runs.Add(currentNode);
            remainingLength = remainingLength - currentNode.GetText().Length;

            // Select the next Run node.
            // Have to loop because there could be other nodes such as BookmarkStart etc.
            do
            {
                currentNode = currentNode.NextSibling;
            }
            while ((currentNode != null) && (currentNode.NodeType != NodeType.Run));
        }

        // Split the last run that contains the match if there is any text left.
        if ((currentNode != null) && (remainingLength > 0))
        {
            SplitRun((Run)currentNode, remainingLength);
            runs.Add(currentNode);
        }


        //// to insert new content
        DocumentBuilder builder = new DocumentBuilder((Document)e.MatchNode.Document);

        builder.MoveTo((Run)runs[runs.Count - 1]);
        builder.InsertImage("C:\\Temp\\Image.png");

        foreach (Run run in runs)
            run.Remove();

        return ReplaceAction.Skip;
    }

    private Run SplitRun(Run run, int position)
    {
        Run afterRun = (Run)run.Clone(true);
        afterRun.Text = run.Text.Substring(position);
        run.Text = run.Text.Substring((0), (0) + (position));
        run.ParentNode.InsertAfter(afterRun, run);
        return afterRun;
    }
}
