Parse json property to a specific type

由 丶灬走出姿态 提交于 2019-12-08 08:19:12
问题 My starting point is something like this (simplified here) : private object GetPropValue(JToken token, Type type) { return JsonConvert.DeserializeObject(token["prop"].ToString(), type); } Usage : var value = GetPropValue(JObject.Parse(someJsonWithAPropertyNamedProp), typeof(someTypeFoundByReflection)); This works, except then the type is string. According to the doc, ToString() of a JValue should return a JSON, but when the JValue is a type string, the value returned is not a JSON, but rather

JSON to Dynamic Object vs. Strongly Typed Object

由 我与影子孤独终老i 提交于 2019-12-08 08:14:36
问题 I'm not sure if I don't get the big picture or if I just miss something but what are the benefits of parsing a JSON-String to a dynamic object? If I have a class like this class Product { public string Name { get; set; } public double Price { get; set; } public string Category { get; set; } } and I use the HttpClient to get the object like this Product product = await response.Content.ReadAsAsync<Product>(); What do I benefit from this code? string content = await response.Content

Which .NET JSON serializers can deal with NHibernate proxy objects?

问题 Which .NET JSON serializers can deal with NHibernate proxy objects? I tried using JSON.NET but it craps out when it hits a proxied object. 回答1: I would say that the best idea would be to deal with the proxy objects rather than actually find another way to serialise JSON. I have answered another question which involves eager loading these proxy objects in a legacy database which returns either the correct object or null here. Please also note that with the proper database set up with foreign

How to custom map property to JSON

由 对着背影说爱祢 提交于 2019-12-08 07:07:54
问题 Desired JSON: "MyRootAttr": { "value": "My Value" } Property definition in the class: public string MyRootAttr { get; set; } So, the question is, without defining a new class, with a single string property, how can i achieve the JSON I want? 回答1: If you don't want to alter your class structure, you can use a custom JsonConverter to achieve the result you want: class WrappedStringConverter : JsonConverter { public override bool CanConvert(Type objectType) { return (objectType == typeof(string)

JSON Serialisation - How to flatten nested object structures using JSON.net/Newtonsoft

由 我与影子孤独终老i 提交于 2019-12-08 06:38:39
问题 I have the following JSON structure : { "Name":"", "Children":[ { "ID":"1", "MetaData":[ { "Info":{ "GUID":"cdee360d-7ea9-477d-994f-12f492b9e1ed" }, "Data":{ "Text":"8" }, "Name":"DataId" } ] } ] } and I want to flatten the MetaData and nested Info and Data objects in the array.

JSON.NET (WebApi2) - Serialize property, but skip during deserialization

由 ╄→гoц情女王★ 提交于 2019-12-08 06:23:23
I know of [JsonIgnore] which ignores properties altogether, I know of ShouldSerializePropertyName which gives conditional serialization, but I cannot find anything to mark property to be serialized into JSON normally, but not set during deserialization. I could write a workaround: [JsonIgnore] public string MyValue{get;set;} public string MyValueForJson {get{return MyValue;} but it is a last resort. Is there some way - other than custom converters etc. - to express that I don't want that field to be populated during deserialization? As I understand you want to serialize object with all
