datacontractserializer

问题 I am trying to find the best way to conditionally include and remove properties from my datacontract serialization in my .net WebApi project. In my Api, I want to allow users to specify the fields that they want returned. For example, assume I want my API to return an instance of the following class. public class Car { public int Id { get; set; } public string Year { get; set; } public string Make { get; set; } public string Model { get; set; } public string Color { get; set; } } But instead

问题 I am serializing an object in code (not via a WCF call), and I am getting a little hung up with known types (I have used them with WCF, but not with the DataContract serializer as a "stand-alone" serializer) I get an exception when I run the code below. I expected it to run without error because I supplied Known Types. What am I getting wrong here? public class Parent {} public class Child: Parent {} // the code -- serialized is a serialized Child // type is typeof(Parent) (I know it works if

问题 I have the following data contract: [CollectionDataContract(Name="MyStuff")] public class MyStuff : Collection<object> {} [DataContract(Name = "Type1")] [KnownType(typeof(Type1))] public class Type1 { [DataMember(Name = "memberId")] public int Id { get; set; } } [DataContract(Name = "Type2")] [KnownType(typeof(Type2))] public class Type2 { [DataMember(Name = "memberId")] public int Id { get; set; } } Which I serialize to xml as follows: MyStuff pm = new MyStuff(); Type1 t1 = new Type1 { Id =

问题 Are there any serialization/deserialization scenarios that DataContractSerializer can handle, while DataContractJsonSerializer can't ? In particular, I am thinking of circular references: this MSDN page explains how circular references can be managed by DataContractSerializer via the use of IsReference = true in the DataContractAttribute constructor. On the other hand, the DataContractAttribute.IsReference documentation does not explicitly state that its applicability is limited to

问题 I'm building an XNA game and I'm trying to save game/map etc. state completely, and then be able to load and resume from exactly the same state. My game logic consists of fairly complex elements (for serializing) such as references, delegates etc. I've done hours of research and decided that it's the best to use a DataContractSerializer that preserves the object references. (I also got around for delegates but that's another topic) I have no problem serializing and deserializing the state, re

问题 MVC3 comes out of the box with JsonValueProviderFactory() which is very handy for binding incoming JSON to a model. Unfortunately, I can't figure out how to setup model contracts with names that differ from the incoming JSON. For example: [DataContract(Name = "session")] public class FacebookSession { [DataMember(Name = "access_token")] public string AccessToken { get; set; } [DataMember(Name = "expires")] public int? Expires { get; set; } [DataMember(Name = "secret")] public string Secret {

问题 Are there any ways to tell WCF to serialize the whole class when it returns? Do I literally have to add DataMember to every property? 回答1: Since .NET 3.5 SP1, you don't have to do this anymore. If you don't have any [DataContract] and [DataMember] attributes, the DataContractSerializer class will behave like the old XmlSerializer: it will serialize all public read/write properties that are listed in the class. You do lose a few things in the process though: since you don't have [DataMember]

问题 I am using a DataContractSerializer to serialize an object to XML. The main object is SecurityHolding with the namespace "http://personaltrading.test.com/" and contains a property called Amount that's a class with the namespace "http://core.test.com". When I serialize this to XML I get the following: <ArrayOfSecurityHolding xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://personaltrading.test.com/"> <SecurityHolding> <Amount xmlns:d3p1="http://core.test.com/"> <d3p1:Amount>1

问题 This seems to be the same question as below but that answer hasn't resolved it: Deserializing a Simple JSON Array I am using DataContractJsonSerializer to convert from XML to JSON and vice versa. Everything works with complex data types and arrays of complex data types but I'm having a problem producing JSON for a string array. The JSON I need to produce should have this structure: { "data": { "x_axis": { "labels": [ "Jan", "Feb", "Mar", "Apr","May", "Jun", "Jul", Aug","Sep", Oct", "Nov",

问题 I'm having an issue where a class decorated with the [DataContract] attribute and appropriate [DataMember] attributes on properties is not serialising nested [DataContract] classes. This is the class i'm trying to serialise: [DataContract(Namespace = "http://foo.bar.com.au")] [KnownType(typeof(Point))] [KnownType(typeof(Site))] public sealed class Alarm : IExtensibleDataObject { [DataMember] public Point SourcePoint { get; set; } [DataMember] public Site SourceSite { get; set; } [DataMember]
