Question

here's my code :

var doc = webBrowser.Document as mshtml.HTMLDocument;
            if (doc != null)
            {
                var currentSelection = doc.selection;
                if (currentSelection != null)
                {
                    var selectionRange = currentSelection.createRange();

Answer 1

public IHTMLTxtRange CurrentSelection
{
    get
    {
        var htmlDocument = webBrowser.Document.DomDocument as IHTMLDocument2;
        IHTMLSelectionObject currentSelection = htmlDocument.selection;
        IHTMLTxtRange range = null;
        if (currentSelection != null)
        {
            range = currentSelection.createRange() as IHTMLTxtRange;
            //range.moveStart("wdCell",1);
            //range.moveEnd("wdCell",1);
        }
        return range;
    }
}
