问题 This question already has answers here : Json.net how to serialize object as value (6 answers) Closed 2 years ago . Sometimes, perhaps in a DDD situation, you might want to use C# to create Value Objects to represent data, to give more meaning to your domain than using primitive types would, with the added benefit of being immutable. For example: public class PostalCode // Bit like a zipcode { public string Value { get; private set; } public PostalCode(string value) { Value = value; } //

问题 In a test I want to populate an object (a view model) from a JSON string. For example, the target object has this property: public string Query { get; set; } So I want to be able to do this: var target = ...; JsonConvert.PopulateObject(target, "{ 'Query': 'test' }"); However, the Query property is not being set. Debugging through the code, it appears that properties on target are ignored because member serialization is opt-in. Since the target class is not a data contract and is not populated

问题 I'm struggling with custom json serialization in .Net core, I'm trying to make all properties required by default except if property has specific type. Here is an example of what I'm trying to achieve: Let's assument that I have following type: F#: type FooType = { id: int name: string optional: int option } you can think about below code as similar to following in C#: class FooType = { int Id {get;set;}; string Name {get;set;}; Nullable<int> Optional {get;set;}; } What I'm trying to do is to

问题 XPath 2 states that the nodes order of a selection should be returned in their order in the document. It looks this is not the case when you SelectTokens(JSONPath) in JSON.Net When I process the following document string json = @" { ""Files"": { ""dir1"": { ""Files"": { ""file1.1.txt"": { ""size:100""}, ""file1.2.txt"": { ""size:100""} } }, ""dir2"": { ""Files"": { ""file2.1.txt"": { ""size:100""}, ""file2.2.txt"": { ""size:100""} } }, ""file3.txt"": { ""size:100""} } }"; The order is the

问题 I am attempting to serialize and deserialize a complex object graph: Class A contains an read only property containing an immutable array of objects of type B . The objects of type B , as well as the immutable array, are created in the constructor of type A . Other types contain references to objects of type B that are obtained by accessing the array of an object of type A . During deserialization, I need any references to a B to end up pointing at the appropriate object created by the A

问题 I have a generic type that wraps a single primitive type to give it value equality semantics public class ValueObject<T> { public T Value { get; } public ValueObject(T value) => Value = value; // various other equality members etc... } It is used like: public class CustomerId : ValueObject<Guid> { public CustomerId(Guid value) : base(value) { } } public class EmailAddress : ValueObject<string> { public EmailAddress(string value) : base(value) { } } The issue is when serializing a type like:

问题 I have the following installed: <package id="Nancy" version="1.4.2" targetFramework="net4" /> <package id="Nancy.Owin" version="1.4.1" targetFramework="net4" /> <package id="Nancy.Serialization.JsonNet" version="1.4.1" targetFramework="net4" /> <package id="Newtonsoft.Json" version="7.0.1" targetFramework="net4" /> <package id="Owin" version="1.0" targetFramework="net4" /> And also: public sealed class Startup { public void Configuration(IAppBuilder app) { var options = new NancyOptions();

问题 Is there a way to get the $type property when using Deserialize ? I serialize with TypeNameHandling on, but when I deserialize, I don't have the assemblies that contain the type information. I need to use the Type name to store it in the right collection, it looks like $type is not brought over to the JObject. Edit: If I deserialize as a JObject, I can get the $type, but if I deserialize as a class that has an object as a property, the type is null. Not sure why its getting stripped out as

问题 My problem is I want to deserialize a json object to a C# object, but the trick is that the C# object contains List< abstract class > and this abstract class is a super class of another 10 classes. public sealed class SearchAPIResult { public string Status; public SearchAPIQuery Query; public SearchResults Result; public SearchAPIResult() { } public SearchAPIResult(string status) { Status = status; } } and SearchAPIResult is: public sealed class SearchResults { public string TextAnswer;

问题 I am trying to parse a JSON string, that looks like that: { "totalCreditsRemoved": 1, "invalidReceivers": [], "ids": [100070531], "validReceivers": ["+33635938286"] } I retrieve this from a web API, and stock it as a String: var reader = new StreamReader(respStream); String result = reader.ReadToEnd().Trim(); response = result; Response is a public string Then, in another method: I try to parse my json string: var json = response; var objects = JArray.Parse(json); foreach (JObject root in
