How to create WCF

1. Create New Project,and select WCF Service Library

2. Delete the two sample,"Service1.cs","IService1.cs"

3. Creat three new items,relatively named "Eval.cs","EvalService.cs","IEval.cs". the code is below:

//Eval.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.Serialization;

namespace EvalLibrary
{
??? [DataContract]
??? public class Eval
??? {?? [DataMember]
??????? public string id;
??????? [DataMember]
??????? public string name;
??? }
}
//EvalService.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;

namespace EvalLibrary
{
??? [ServiceBehavior(InstanceContextMode=InstanceContextMode.Single)]
??? public class EvalService:IEval
??? {

??????? #region IEval Members

??????? List<Eval> evals = new List<Eval>();
??????? public void Sumbit(Eval eval)
??????? {
??????????? eval.id = Guid.NewGuid().ToString();
??????????? evals.Add(eval);
??????? }

??????? public List<Eval> GetEval()
??????? {
??????????? return evals;

??????? }

??????? public void Remove(string id)
??????? {

??????????? evals.Remove(evals.Find(e => e.Equals(id)));
??????? }

??????? #endregion
??? }
}

//IEval.cs

?

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;

namespace EvalLibrary
{
??? [ServiceContract]
??? public interface IEval
??? {
??????? [OperationContract]
??????? void Sumbit(Eval eval);
??????? [OperationContract]
??????? List<Eval> GetEval();
??????? [OperationContract]
??????? void Remove(string id);

??? }
}

4. Right click the "App.config",configure "contact" for "Endpoits"?you wanted?and "name" for "EvalLibrary.EvalService"

5. Enter "F5" to test the methods in this service

?

by the way,you can add this service into reference into a website like? webservice,and? also configure it onto IIS,such as create new virtual directory?,the reference is the?similar in the? windows form application
