问题 I have read a few pieces of conflicting information regarding MVC 4's out-of-the-box support for JSON.NET I gathered that MVC is serializing JSON by default using JSON.NET now, however I still have the tell-tale MS date format in my JSON output.

问题 What is the difference between the JToken.ToObject<T>() method and the JToken.Value<T>() extension method (the one without the key parameter)? var jToken = JToken.Parse("123"); var toObjectStrResult = jToken.ToObject<string>(); var valueStrResult = jToken.Value<string>(); // toObjectStrResult == valueStrResult == "123" var toObjectLongResult = jToken.ToObject<long>(); var valueLongResult = jToken.Value<long>(); // toObjectLongResult == valueLongResult == 123L 回答1: The difference is as follows

问题 I use Metadata and JsonIgnore to remove special field from being serializing. [Authorize(Roles = "admin")] public class UserController : ApiController { public IEnumerable<user> Get() { using (var mydb = new ModelContainer()) { return mydb.userSet.ToList(); } } } [MetadataType(typeof(user_Metadata))] public partial class user { private class user_Metadata { [JsonIgnore] public virtual password { get; set; } public virtual adminFile { get; set; } } } How can I dynamic control which field

问题 I am trying to create a configuration file using Json that will hold configuration for various types of objects. Consider this file: { "cameras": [ { "type": "Some.Namespace.CameraClass", "assembly": "Some.Assembly", "configuration": { "ip": "127.0.0.1", "port": 8080 } } ] } At runtime I will use the two "type" and "assembly" properties to construct an object supporting a specific interface, and then I would like to load the configuration into that object. However, at compile time I do not
