deserialization

问题 I'm writing an app that gets a Json list of objects like this: [ { "ObjectType": "apple", "ObjectSize": 35, "ObjectCost": 4, "ObjectTaste": "good", "ObjectColor": "golden" }, { "ObjectType": "books", "ObjectSize": 53, "ObjectCost": 7, "Pages": 100 }, { "ObjectType": "melon", "ObjectSize": 35, "ObjectTaste": "good", "ObjectCost": 5 }, { "ObjectType": "apple", "ObjectSize": 29, "ObjectCost": 8, "ObjectTaste": "almost good", "ObjectColor": "red" } ] I want to make a base class ItemToSell (size

问题 Update: I tried to debug in jackson source code and find out that in the method deserialize(JsonParser jp, DeserializationContext ctxt) of SettableBeanProperty.java when the _valueTypeDeserializer isn't null, it will never use _valueDeserializer . Is this a correct assumption that TypeDeserializer should be more proper than ValueDeserializer? I'm trying to use @JsonDeserialize to define custom deserializer for one field with polymorphic types. I can succeed to use @JsonDeserialize and

问题 We are using protobuf.net to serialize classes between mobile devices and back end services, but we now need to adjust what is sent back to the client based upon the 'context' of the user. We would typically do this by implementing the ISerializable interface and look at the context value to then decide what to serialize. Similarly in the constructor we would then deserialize the provided values. But it would appear that ISerializable isn't implemented/support (i can see why) for protobuf.net

问题 I need some help with XmlSerializer. I have to following xml fragment: <?xml version='1.0' encoding='UTF-8'?> <?xml-stylesheet href="http://www.blogger.com/styles/atom.css" type="text/css"?> <feed xmlns='http://www.w3.org/2005/Atom' xmlns:openSearch='http://a9.com/-/spec/opensearchrss/1.0/' xmlns:georss='http://www.georss.org/georss' xmlns:gd='http://schemas.google.com/g/2005' xmlns:thr='http://purl.org/syndication/thread/1.0'> <id>tag:blogger.com,1999:blog-4233645339430781865.archive</id>

问题 I try to deserialize xml file: <?xml version="1.0" encoding="utf-8"?> <XmlFile xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <OBJECTS ITEM="ItemValue" TABLE_NAME="TableExample"> </OBJECTS> </XmlFile> My deserialize class code looks like that: [Serializable] [XmlRoot("XmlFile")] public class SerializeObject { [XmlAttribute("ITEM")] public string Item { get; set; } [XmlAttribute("TABLE_NAME")] public string Table_Name { get; set; } } When I

问题 Here is my code: public static void Save<T>(T toSerialize, string fileSpec) { BinaryFormatter formatter = new BinaryFormatter(); DESCryptoServiceProvider des = new DESCryptoServiceProvider(); using (FileStream stream = File.Create(fileSpec)) { using (CryptoStream cryptoStream = new CryptoStream(stream, des.CreateEncryptor(key, iv), CryptoStreamMode.Write)) { formatter.Serialize(cryptoStream, toSerialize); cryptoStream.FlushFinalBlock(); } } } public static T Load<T>(string fileSpec) {

问题 I have a JSON stream being generated by a server side C++ program that is currently in development. I've been given a sample of the resulting JSON and I am concerned that I will have to parse the json by hand, that I won't be able to use normal class mapping provided by tools such as GSON or Jackson. Please take a look at the following (somewhat) contrived example they have provided. The sections I'm concerned with are the meta data "serie" array having different parameters. The key - "key"

问题 How Could I store integers (user id's ranging from 1 to 9999) serialized in a database column and retrieve them back? In my User model I have invites column, User model serialize: invites invites = text field Now I'm trying to do 2 things: Append the user_id integer (from 1 to 9999) serialized in a column "invites" Retrieve all the user id's back from the User.invited column ( deserialize it ? ) 回答1: From the fine manual: serialize(attr_name, class_name = Object) If you have an attribute that
