Define Data Contract and Service Contact in IService1.cs. Note RequestFormat
and ResponseFormat is Json as we want our service to return and accept
Json. WebGet attribute is used to specify that method will be available
through REST call. You can use [WebInvoke(Method ="Post"]
attribute we you want to send updated data to the server. UriTemplate defines
how Url will be mapped with service method.</span><br />

<b><span style="color: purple;">Consuming REST service in ASP.NET web
application project :<br />
<br />
</span></b><span style="mso-spacerun: yes;"> </span>1. Add following namespaces
in the class were you want to communicate with REST service as we will
deserialize the Json response into Person class using
DataContractJsonSerializer. <span style="mso-spacerun: yes;">
</span><br />
<span style="color: blue;"><span style="mso-spacerun: yes;"> </span>using </span>System.ServiceModel;<br />
<span style="mso-spacerun: yes;"> </span><span style="mso-spacerun: yes;"> </span><span style="color: blue;">using </span>System.ServiceModel.Web;<br />
<span style="mso-spacerun: yes;"> </span><span style="mso-spacerun: yes;"> </span><span style="color: blue;">using </span>System.Runtime.Serialization.Json;<br />
(You may require to add reference to System.ServiceModel.Web and
System.Web.Extensions dll in the project as Serialization.Json may not be
available by default) <br />
<br style="mso-special-character: line-break;" />
<br />
2. Create a Person class into which we will deserialize the Json response
from calling GetAllPerson of REST service<br />
<span style="color: blue;">public class</span>
Person <br />
<span style="mso-spacerun: yes;"> </span>{<br />
<span style="mso-spacerun: yes;"> </span><span style="color: blue;">public int
</span>ID;<br />
<span style="mso-spacerun: yes;"> </span><span style="color: blue;"><span style="mso-spacerun: yes;"> </span>public string</span> Name;<br />
<span style="mso-spacerun: yes;"> </span><span style="color: blue;"><span style="mso-spacerun: yes;"> </span>public int</span> Age;<br />
<span style="mso-spacerun: yes;"> </span><span style="mso-spacerun: yes;"> </span>}<br />
<br />
3. Now to call REST service and read response we will use WEBClient
object :<br />
<br style="mso-special-character: line-break;" />
<br />
WebClient objClient = new WebClient();<br />
<span style="mso-spacerun: yes;"> </span>byte[] data = objClient.DownloadData("<span style="color: blue;">http://localhost:53810/Service1.svc/Persons</span>");<br />
<span style="mso-spacerun: yes;"> </span>Stream st = new MemoryStream(data); <br />
<br />
<span style="mso-spacerun: yes;"> </span>DataContractJsonSerializer obj = new
DataContractJsonSerializer(typeof(List<Person>));<br />
<span style="mso-spacerun: yes;"> </span>List<Person> result =
(List<Person>)obj.ReadObject(st);<br />
<span style="mso-spacerun: yes;"> </span><span style="mso-spacerun: yes;"> </span>Response.Write(result[0].Name);Abhishekhttp://www.blogger.com/profile/08577772590377898678noreply@blogger.com0tag:blogger.com,1999:blog-6935454472766450349.post-20663352135065475582011-09-20T09:11:00.000-07:002011-09-20T09:17:27.151-07:00Dynamically generate a MS Word document using HTML & CSS<div dir="ltr" style="text-align: left;" trbidi="on"><pre style="background-color: #fff2cc;">Public Sub Page_Load(sender as Object, e as EventArgs)
