问题 I am having some trouble figuring out a clean (as possible) way to deserialize some JSON data in a particular format. I want to deserialize the data to strongly typed data object classes, pretty flexible regarding the specifics of this. Here is an example of what the data looks like: { "timestamp": 1473730993, "total_players": 945, "max_score": 8961474, "players": { "Player1Username": [ 121, "somestring", 679900, 5, 4497, "anotherString", "thirdString", "fourthString", 123, 22,

问题 ASP.Net Core 2.2 allows to set serializer settings using MvcJsonOptions.SerializerSettings property. The problem is that it affects both input and output. Is there a way to have separate options for input (deserialization) and output (serialization)? In particular, I need to set a different behavior for NullValueHandling settings: ignore null errors for non-nullable fields when deserializing client json but keep nulls for defined model fields when serializing the result. For example, I have a

问题 I'm trying to deserialize some json from a 3rd party provider, and occasionally it returns some invalid date field (like -0001-01-01 or something). This causes the process to throw an exception. Is there a way to tell Json.Net to ignore fields that are invalid? Thanks Matt 回答1: To expand on the answer from David, I have used a custom DateTime converter: public class SafeDateTimeConvertor : DateTimeConverterBase { public override object ReadJson(JsonReader reader, Type objectType, object

问题 I have a JSON resonse (HTTPWebResponse) coming back from my WCF Service. It looks like this : { "New SessionResult": [ { "Key": "Token", "Value": "token_value" } ] } I am using JSON.NET (http://james.newtonking.com) and I cant figure out how to deserialize this response into a Dictionary<string, string>. I have tried several things but each one says in different wording "cannot convert JSON into sting". Currently I tried this : Dictionary<string, string> values = JsonConvert.DeserializeObject

问题 In my WPF code, I'm using Newtonsoft.Json to deserialize json into my models. First, I receive a Json string ('json') which I then parse into 'message'. (The object I want to deserialize is wrapped in a "data" field in the json string). Activity message = JObject.Parse(json)["data"].ToObject<Activity>(); My Activity class uses several [JsonProperty] attributes to generate its fields. One of them is an enum called 'ActivityType'. [JsonProperty("type")] [JsonConverter(typeof

问题 I want to deserialize a JSON structure like this: { "Name": "Foo", "bar": { "Name": "Bar", "DefaultableProperty": "default" } } ... where it is optional to define "bar" . And in the case that it is not defined, I want to load an object of type Bar with some default values. Here are my class definitions for Foo and Bar public class Foo { [JsonConstructor] public Foo() { string bardefaults = @"{ ""Name"": ""defaultname""}"; b = new Bar(bardefaults); } public string Name { get; set; } public Bar

问题 I have a class that has a field of type Object that may contain a TimeSpan object.

How can I get this to

问题 I am getting a response back from a Google Search Appliance suggest service in the form of JSON in the following format string jsonString = @"{ ""query"": ""t"", ""results"": [ { ""name"": ""tom"", ""type"": ""suggest"" }, { ""name"": ""tim"", ""type"": ""suggest"" }]}"; I want to sort the results list by name alphabeticaly and change the names to sentence case. I can do this in jquery but would prefer to do it on the server side for performance reasons. I can sort the results but that
