I have been using your product for more than 6 years and I finally upgradet to the latest veriosn. There was rather a lot of changes I had to do in my code and I have managed most of them. However, I need help with the following: I have this line of code;

doc.Range.Replace(new Regex((@"[[Lönetillägg]]"), RegexOptions.IgnoreCase), new Utskick.ReplaceEvaluator(), false);

which is marked as obsolete. The ReplaceEvaluator looks like this:

public 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))
remainingLength = remainingLength - currentNode.GetText().Length;

// Select the next Run node.
// Have to loop because there could be other nodes such as BookmarkStart etc.
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);

// Create Document Buidler
DocumentBuilder builder = new DocumentBuilder(e.MatchNode.Document as Aspose.Words.Document);

builder.MoveTo((Run)runs[runs.Count - 1]);

string bookm = e.Match.Value.Replace("[[", “”).Replace("]]", “”);
//Your code comes here
// Now remove all runs in the sequence.
foreach (Run run in runs)

// Signal to the replace engine to do nothing because we have already done all what we wanted.
return ReplaceAction.Skip;


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

What shall I do instead?

Best regards

Hi Robert,

Thanks for your inquiry. Please note that ReplaceAction, IReplacingCallback and ReplacingArgs are now moved to Aspose.Words.Replacing namespace.Please refer to the release notes:
Aspose.Words for .NET 16.7.0 Release Notes

Please use the following code to find and replace the text.

FindReplaceOptions options = new FindReplaceOptions();

options.ReplacingCallback = new ReplaceEvaluator();

int count = doc.Range.Replace(new Regex((@"\[\[Lönetillägg\]\]")), "", options);
