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
