@SalesDhorde, 以下是用图像替换单词 computer 的示例：

string image = "computer.png";

Document doc = new Document("in.docx");

FindReplaceOptions options = new FindReplaceOptions
{
    MatchCase = false,
    ReplacingCallback = new ReplaceTextWithImage(image)
};

doc.Range.Replace("computer", "", options);
doc.Save("out.docx");


public class ReplaceTextWithImage : IReplacingCallback
{
    private string mImage;
    public ReplaceTextWithImage(string image)
    {
        mImage = image;
    }

    public ReplaceAction Replacing(ReplacingArgs args)
    {
        Node currentNode = args.MatchNode;
        Console.WriteLine("here");

        // 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 (args.MatchOffset > 0)
            currentNode = SplitRun((Run)currentNode, args.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 = args.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)args.MatchNode.Document);
        builder.MoveTo((Run)runs[runs.Count - 1]);

        // Insert image
        Shape img = builder.InsertImage(mImage);
        img.WrapType = WrapType.Inline;
        img.Width = 20;
        img.Height = 20;

        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;
    }
}
