Answer 1

Using Linq

 var jArr = JArray.Parse(json); jArr.Descendants().OfType<JProperty>() .Where(p => p.Name == "attachments") .ToList() .ForEach(att=>att.Remove()); var newJson = jArr.ToString(); 

or using anonymous classes

 var anon = new[] { new{spent_hours="", description=""} }; var newJson = JsonConvert.SerializeObject( JsonConvert.DeserializeAnonymousType(json, anon));
