How to handle error in Json.Net parsing

由 ↘锁芯ラ 提交于 2019-12-07 07:55:04
问题 I'm using Json.Net for Json deserialization. On occasion the Json string I read is not correct (which I can't fix since I don't produce it). In particular, at one specific place, where there should be a string, sometimes there is a serialized object instead. Json.Net then complains, not surprisingly, about finding an object where it expected a string. I found I can intercept this by using Error in JsonSerializerSettings and also make Json.Net ignore the problem by setting ErrorContext.Handled

JSON.NET customizing the serialization to exclude a property name

由 回眸只為那壹抹淺笑 提交于 2019-12-07 06:59:28
I am using Json.NET and I have the following code. public class Row { [JsonProperty] public IDictionary<string, object> Cells { get; set; } } The rows and cells are dynamically generated and I had C# dynamic/Expando feature to create those Cells. When Json.NET serializes the dynamic instances, it produces the correct json structure I want. However for a large data structure it has an adverse effect on the performance. For example, JsonSerializer calls DynamicObject TryGetMember quite extensively during the serialization. Therefore I needed a static data structure so the serialization would be

Why can't use LINQ methods on JObject?

由 风流意气都作罢 提交于 2019-12-07 06:42:37
问题 Newtonsoft.Json.Linq.JObject implemented IEnumerable<T> , and not explicit implementation, but why can't do this: using System.Linq; ... var jobj = new JObject(); var xxx = jobj.Select(x => x); //error foreach(var x in jobj) { } //no error WHY? Thanks. 回答1: JObject implements both IEnumerable<KeyValuePair<string, JToken>> and IEnumerable<JToken> (by inheriting from JContainer ). Thus you cannot use LINQ (e.g. Select ) directly since it doesn't know which of the enumerables to 'extend'. Thus
