serialization

问题 I have this class: using System; using System.Collections.Generic; using System.Runtime.Serialization; namespace Grouping { [Serializable] public class Group<T> : HashSet<T> { public Group(string name) { this.name = name; } protected Group(){} protected Group(SerializationInfo info, StreamingContext context):base(info,context) { name = info.GetString("koosnaampje"); } public override void GetObjectData(SerializationInfo info,StreamingContext context) { base.GetObjectData(info,context); info

问题 When using Scala RemoteActors I was getting a ClassNotFoundException that referred to scala.actors.remote.NetKernel. I copied someone else's example and added RemoteActor.classLoader = getClass.getClassLoader to my Actor and now everything works. Why is this necessary? 回答1: Remote Actors use Java serialization to send messages back and forth. Inside the actors library, you'll find a custom object input stream ( https://lampsvn.epfl.ch/trac/scala/browser/scala/trunk/src/actors/scala/actors

问题 I have two c++ programs that need to have a map type -> int that is known at compile time and equal between the two programs. Furthermore, I'd like to automatically make sure at compile time that the map is one-to-one. How would you solve that? (c++0x-extensions are allowed). The first part is easy: Share a template < typename T > struct map; template <> struct map <...> { enum { val = ...; }; }; between the programs. (The second part means that I don't want to accidently define the same val

问题 I have a common class library containing many models for my server and my client. Since the client is running under Xamarin, the common library must be a Portable Class Library (PCL). In my server, these objects are passed around with AppDomain Remoting/Marshaling, so to my understanding an object either needs to be marked as [Serializable] or inherit from MarshalByRefObject Being in a PCL, I cannot do either of these things to any of my models. My question is: How can I make these objects

问题 In ASP.NET WebForms I want to pass arbitrary data from server to client and back again. I am serializing to JSON and have been simply producing JavaScript that creates the object on the client. I have no problem sending data to the server with ajax, but there are situations where I also want to send a Javascript object data back to the server on postbacks. So I guess it needs to be in a hidden field. A couple general questions about this. 1) What is the best way to do this in terms of

问题 i'm trying to serialize DataTable to Json or XML. is it possibly and how? any tutorials and ideas, please. For example a have a sql table: CREATE TABLE [dbo].[dictTable]( [keyValue] [int] IDENTITY(1,1) NOT NULL, [valueValue] [int] NULL, CONSTRAINT [Psd2Id] PRIMARY KEY CLUSTERED ( [keyValue] ASC )WITH (PAD_INDEX = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY] ) ON [PRIMARY] C# code: string connectionString = "server=localhost;database=dbd;uid=**;pwd=**"; SqlConnection mySqlConnection = new

问题 I have the following ServiceContract and DataContract classes: [ServiceContract] public interface IWcfService { [OperationContract] Response GetData(); } [DataContract] public class Response { [DataMember] public Dictionary<string, object> Data { get; set; } } When the value of Response.Data dictionary is of type int, string, double or any other 'simple' primitive types, WCF can successfully serialize the object. But when the value of Response.Data dictionary is of type List< string>, the

问题 How can I tell proguard to keep my classmembers? I need them for JSON compatibility... This is my class: package com.tools.app.holiday; public class Holiday { private String name; private Calendar dateFrom = Calendar.getInstance(); private Calendar dateTo = Calendar.getInstance(); ... I already tried, but it doesnt work... -keepclassmembers class com.tools.app.holiday.Holiday -keepclassmembers class com.tools.app.holiday.Holiday *{ private String name; private Calendar dateFrom; private

问题 For the following code var address = new Address(); address.street = 'N 34th'; address.city = 'Seattle'; var serialization = new Serialization() ..addRuleFor(address); String output = serialization.write(address); How do i get a json output like this: address: {'street':'N 34th', 'city':'Seattle'} Output generated by above code is as follows: {"roots":[{"__Ref":true,"rule":3,"object":0}],"data":[[],[],[],[["Seattle","N 34th"]]],"rules":"{\"roots\":[{\"__Ref\":true,\"rule\":1,\"object\":0}],\
