Deserialize JSON with json.NET into C# dynamic

阅读更多关于 Deserialize JSON with json.NET into C# dynamic

I have following problem: I have a json file that looks like this { "Path": { "FirstPath": "/1/2/text()" } } If I parse this JSON-File with Newtonsoft like this dynamic dyn = JObject.Parse(json); or this dynamic dyn = JsonConvert.DeserializeObject(json); I get a dynamic object that needs to be used like this dyn.Path.FirstPath.Value How can I get rid of the Value stuff? All of my objects in the JSON end up being a string. I don't want to always write ".Value" at the end if it is not necessary. I tested this using Newtonsoft 8.0.2 and it works fine. dynamic dyn = JObject.Parse(json); string

How to set Json.NET ContractSerializer for a certain specific type instead of globally?

阅读更多关于 How to set Json.NET ContractSerializer for a certain specific type instead of globally?

I want to set a contract serializer just for certain types in my ASP.NET Web API application. I can set the settings globally in the App_Start/FormatterConfig.cs like this: public static void RegisterGlobalFormatters(MediaTypeFormatterCollection formatters) { jsonSerializerSettings.ContractResolver = new CriteriaContractResolver(new List<string>(new string[]{"mdData", "name", "label"})); ... but how can I just apply this to one or more specific class types? The reason I want to do this is because I need to be able to set what fields should be serialized at runtime based on configuration or

问题 When adding a new object to a JArray each object is added to the first entry in the array ([0]) along with being appended to the array. response = client.GetAsync(new Uri(urlIndexDoc)).Result; result = response.Content.ReadAsStringAsync().Result; JObject OPDDoc = JObject.Parse(result); JArray indexCEM = new JArray(); JObject oNew = new JObject(); int idxcount = Convert.ToInt32(ConfigurationManager.AppSettings["IndexCount"]) + 1; for (int i = 1; i < idxcount ; i++) { string istring = i

问题 I have an API that returns a big list of car features.... all are either bool or ints... and basically I only want to display the ones that return true values or >0 for the ints. I am using JSON.net so that I san use the ShouldSerialize() property to determine if I should serialize the property based upon its value and my code looks like this: public class Features { public bool ABS { get; set; } public bool ShouldSerializeABS() { // don't serialize the ABS property if ABS is false return

问题 Am using a custom JsonConverter to convert my JSON object. This is achieved via the JsonConverter attribute to the IQuery object below [JsonConverter(typeof(CustomConverter<IQuery>))] public interface IQuery { } The custom generic class is below (some bits removed for brevity) public class CustomConverter<T> : JsonConverter { // This should be created via AutoFac public ICustomObjectCreator<T> ObjectCreator { get; set; } // This default constructr always gets called public CustomConverter() {

JSON.NET Why does it Add to List instead of Overwriting?

问题 public class MyClass { public List<int> myList = new List<int> { 1337 }; public MyClass() {} } var myClass = JsonConvert.DeserializeObject<MyClass>("{myList:[1,2,3]}"); Console.WriteLine(string.Join(",", myClass.myList.ToArray())); //1337,1,2,3 Why does it display 1337,1,2,3 instead of 1,2,3? Is there a way/setting to make JSON.NET overwrite List instead of adding elements to it? I need a solution that doesn't modify the constructor. 回答1: If you don't want this behavior, you can change it by

Getting SerializeObject to use JsonProperty “name” defined inside interface

阅读更多关于 Getting SerializeObject to use JsonProperty “name” defined inside interface

问题 When calling "JsonConvert.SerializeObject" I am passing in an object that implements an interface. It is the interface that defines the JsonProperty attributes to set the desired JSON object property name. However when I examine the JSON object that is produced it is using the actual .NET property name, rather than JsonPropertyAttribute value. This leads me to believe it is only reflecting over the implementation of the interface to find the JsonProperty attributes, rather than the interface

Insert a single object into json file without rewriting entire file

阅读更多关于 Insert a single object into json file without rewriting entire file

问题 I'm working on a method that uses JSON.NET to add a horse object to a JSON-formatted database of horses. One option is to deserialize the entire file into a list of horses, add the new horse, then serialize the list and rewrite the whole file. I've implemented this approach in the code below. // adds a horse to the db public int AddHorse(Horse horse) { // identify and assign next available id to horse var horses = GetAllHorses(); int nextId = horses.Max(h => h.ID) + 1; horse.ID = nextId; //
