WCF Example: Simple example for RESTful type

Below Example describes how to create and access WCF RESTful type service and hosted in IIS.

Also example shows JSON type data.

Create a WCFService Project in Visual Studio

Ex: WcfTest

1.       Write the following code in IService1.cs

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Web;

namespace WcfTest

{

    // NOTE: If you change the interface name "IService1" here, you must also update the reference to "IService1" in Web.config.

    [ServiceContract]

    public interface IService1

    {

        [OperationContract]

        [WebGet(

            RequestFormat = WebMessageFormat.Json,

            ResponseFormat = WebMessageFormat.Json,

            UriTemplate = "/GetNameById?id={id}")]

        string GetNameById(string id);

        [OperationContract]

        [WebGet(

            RequestFormat = WebMessageFormat.Json,

            ResponseFormat = WebMessageFormat.Json,

            UriTemplate = "/GetCompany")]

        string GetCompany();

        [OperationContract]

        [WebGet(

            RequestFormat = WebMessageFormat.Json,

            ResponseFormat = WebMessageFormat.Json,

            UriTemplate = "/")]

        string TestMethod();

        [OperationContract]

        [WebGet(

            RequestFormat = WebMessageFormat.Json,

            ResponseFormat = WebMessageFormat.Json)]

        List<Employee> GetEmployees();

    }

    [DataContract]

    public class Company

    {

        string compName = "Company Name";

        string location = "Bangalore";

        [DataMember]

        public string CompName

        {

            get { return compName; }

            set { compName = value; }

        }

        [DataMember]

        public string Location

        {

            get { return location; }

            set { location = value; }

        }

        [DataMember]

        public string CompanyAddress

        {

            get { return (CompName + " " + Location); }

        }

    }

    [DataContract]

    public class Employee

    {

        string firstName = string.Empty;

        string secondName = string.Empty;

        string address = string.Empty;

        [DataMember]

        public string FirstName

        {

            get { return firstName; }

            set { firstName = value; }

        }

        [DataMember]

        public string SecondName

        {

            get { return secondName; }

            set { secondName = value; }

        }

        [DataMember]

        public string Address

        {

            get { return address; }

            set { address = value; }

        }

    }

}

1.       Write the following code in Service1.svc.cs file

using System.Runtime.Serialization;

using System.Web.Script.Serialization;

using System.ServiceModel;

namespace WcfTest

{

    // NOTE: If you change the class name "Service1" here, you must also update the reference to "Service1" in Web.config and in the associated .svc file.

    public class Service1 : IService1

    {

        #region IService1 Members

        public string GetNameById(string id)

        {

            return "hello " + id;

        }

        public string GetCompany()

        {

            Company comp = new Company();

            StringBuilder sbJson = new StringBuilder();

            new JavaScriptSerializer().Serialize(comp, sbJson);

            return sbJson.ToString();

        }

        public string TestMethod()

        {

           return "Company, Bangalore, India";

        }

        public List<Employee> GetEmployees()

        {

            List<Employee> employeesList = new List<Employee>();

            Employee employee = null;

           

            employee = new Employee();

            employee.FirstName = "Sharath";

            employee.SecondName = "Kumar";

            employee.Address = "Bangalore";

            employeesList.Add(employee);

            employee = new Employee();

            employee.FirstName = "Employee2First";

            employee.SecondName = "Employee2Second";

            employee.Address = "Bangalore, Jayanagar";

            employeesList.Add(employee);

            return employeesList;

        }

        #endregion

    }

}

1.       Verify this entry in Service1.svc

<%@ ServiceHost Language="C#" Debug="true" Service="WcfTest.Service1" CodeBehind="Service1.svc.cs" Factory="System.ServiceModel.Activation.WebServiceHostFactory" %>

2.  Write the the following in web.config in Service model

  <system.serviceModel>

   <!--http://localhost/WCFTest/Service1.svc-->

    <services>

      <service name="WcfTest.Service1" behaviorConfiguration="WcfTest.Service1Behavior">

        <endpoint address="" behaviorConfiguration="web"

                  binding="webHttpBinding”

                  contract="WcfTest.IService1">

          <identity>

            <dns value="localhost"/>

          </identity>

        </endpoint>

        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>

      </service>

    </services>

    <behaviors>

      <serviceBehaviors>

        <behavior name="WcfTest.Service1Behavior">

          <serviceMetadata httpGetEnabled="true"/>

          <serviceDebug includeExceptionDetailInFaults="false"/>

        </behavior>

      </serviceBehaviors>

      <endpointBehaviors>

        <behavior name="web">

          <webHttp />

        </behavior>

        <behavior name="web2">

          <webHttp />

        </behavior>

      </endpointBehaviors>

    </behaviors>

</system.serviceModel>

3.       Publish the application and Host the in IIS (Add Ppplication in DefaultApplication and give the Published path in Physical Path)

4.       Try accessing the following URL

http://localhost/WCFTest/Service1.svc/

Result: "Company, Bangalore, India"

http://localhost/WCFTest/Service1.svc/GetNameById?id=200

Result: "hello 200"

http://localhost/WCFTest/Service1.svc/GetCompany

Result (Object in JSON format): "{\"CompName\":\"Company Name\",\"Location\":\"Bangalore\",\"CompanyAddress\":\"Company Name Bangalore\"}"

http://localhost/WCFTest/Service1.svc/GetEmployees

Result:

[{"Address":"Bangalore","FirstName":"Sharath","SecondName":"Kumar"},{"Address":"Bangalore, Jayanagar","FirstName":"Employee2First","SecondName":"Employee2Second"}]

Thanks,
