serialization

问题 Consider the following Student defintion: public class Student { public Guid Id {get; set;} public String FirstName {get; set;} public String LastName { get; set; } } Using C# serialization attributes, how can you apply two different serialization configurations?

I have a two runtime use cases: Only serialize the Guid Full serialization of the Object. 回答1: I don't know

问题 I've been trying to figure out how to get this to work for along time but without any luck. Due to a complex logic in an app I'm working on, I need to create an isolated clone of a entity collection without preserving what so ever relation to the database. Whatever changes I do on the cloned collection should not be tracked by Doctrine at all and should be treated as if it doesn't exist at all. Here's an example code: /* * @ORM\Entity() */ class Person { /** * @var integer * * @ORM\Id * @ORM

问题 I have the following code import com.google.gson.Gson; /** * * @author yccheok */ public class JavaApplication18 { public static class Holder { public Object value; } /** * @param args the command line arguments */ public static void main(String[] args) { Gson gson = new Gson(); Integer i = new Integer(123); Holder holder = new Holder(); holder.value = i; String json = gson.toJson(holder); System.out.println(json); Holder newHolder = gson.fromJson(json, Holder.class); System.out.println

问题 I have the following ComboBox in my MainWindow.xaml: <ComboBox ItemsSource="{Binding ComboItemsProperty}" /> In MainWindow.xaml.cs: ObservableCollection<string> ComboItemsField = new ObservableCollection<string>(); public ObservableCollection<string> ComboItemsProperty { get { return ComboItemsField; } set { ComboItemsField = value; } } This works perfectly! I can add items to the Property and successfully Serialize the ComboBox Element. My question is, why is it when I have this EXACT code

问题 I have a class which contain an interface member variable.How can i deserialize this class interface ISensor { } [Serializable] class Sensor: ISensor { } [Serializable] class Root { [XmlElement("Sensor")] public List<ISensor> SensorList{ get; set; } } My XML will be like this <?xml version="1.0" encoding="us-ascii"?> <Root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Sensor > <SensorName>Name1</SensorName> <SensorValue>0.0</SensorValue>

问题 I have an EventType and Events classes to serialize/deserialize. In Xml for Events there is a XmlElement named "type". <?xml version="1.0" encoding="UTF-8"?> <events type="array"> <event> <where /> <project-users-can-edit type="boolean">false</project-users-can-edit> <description /> <attending-user-ids type="integer">164316</attending-user-ids> <notify-user-names>Levent A.</notify-user-names> <attending-user-names>Levent A.</attending-user-names> <status>active</status> <owner> <first-name

问题 I have a simple class derived from a generic list of string as follows: [Serializable] [System.Xml.Serialization.XmlRoot("TestItems")] public class TemplateRoleCollection : List<string> { } when I serialize this, I get the following XML: <TestItems> <string>cat</string> <string>dog</string> <string>wolf</string> </TestItems> Is there any way to override the xml element name which is used for serializing items in the collection? I would like the following xml to be produced: <TestItems>

问题 This idea started with this question. 2 models: class Trail < ApplicationRecord has_many :notes, dependent: :destroy end class Note < ApplicationRecord belongs_to :trail end 2 serializers: class NotesSerializer < ActiveModel::Serializer attributes :id, :note_body belongs_to :trail end class TrailSerializer < ActiveModel::Serializer attributes :id, :name, :notes_count has_many :notes def notes_count object.notes.size end end When calling the route trails/index, this will fire for every Trail,

This is the error: No parameterless constructor defined for type of 'System.String[]'. Client-Side function upload() { var title = []; var files = $('#myfile').prop("files"); var names = $.map(files, function (val) { return val.name; }); for
