  1. POBest approach to a class representing JSON with variable parameters in C#
    text
    copied!<p>I have a webservice in WCF whose operations require requests and responses in JSON format. I know that I can just write C# objects with properties that I want represented in JSON, but my problem is that the JSON parameters may change. For example, my method contract is the following:</p> <pre><code> [WebInvoke(Method = "PUT", UriTemplate = "users", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)] [OperationContract] Response PutUserAccount(User user); </code></pre> <p>User's parameters may contain any number of parameters, so an instance of User may be sometimes:</p> <pre><code>{ "Name" : "John", "LastName" : "Doe", "Email" : "jdoe@gmail.com", "Username" : "jdoe", "Gender" : "M" "Phone" : "9999999" } </code></pre> <p>or even:</p> <pre><code>{ "Name" : "John", "LastName" : "Doe", "Email" : "jdoe@gmail.com", "Username" : "jdoe", "FavoriteColor" : "Blue" } </code></pre> <p>What is the best approach to have an object with a mutable number of properties to represent a JSON document?</p> <p><strong>EDIT</strong> This class allowed me to have a flexible JSON representation, since I can't use a <code>JObject</code> with WCF (Should I post this as answer?):</p> <pre><code>using System; using System.Collections.Generic; using System.Runtime.Serialization; namespace MyNamespace { [Serializable] public class Data : ISerializable { internal Dictionary&lt;string, object&gt; Attributes { get; set; } public Data() { Attributes = new Dictionary&lt;string, object&gt;(); } public Data(Dictionary&lt;string, object&gt; data) { Attributes = data; } protected Data(SerializationInfo info, StreamingContext context) : this() { SerializationInfoEnumerator e = info.GetEnumerator(); while (e.MoveNext()) { Attributes[e.Name] = e.Value; } } public void GetObjectData(SerializationInfo info, StreamingContext context) { foreach (string key in Attributes.Keys) { info.AddValue(key, Attributes[key]); } } public void Add(string key, object value) { Attributes.Add(key, value); } public object this[string index] { set { Attributes[index] = value; } get { if (Attributes.ContainsKey(index)) return Attributes[index]; else return null; } } } </code></pre> <p>}</p>
