Create WCF REST service.

Create ASP.NET website to consume service.

Step 1(Creating Service)

IService1.cs

  1. [ServiceContract]
  2. public interface IService1
  3. {
  4. [OperationContract]
  5. [WebInvoke(Method = "GET", UriTemplate = "Add/{num1}/{num2}")]
  6. string Add(string num1, string num2);
  7. }
  8. Service1.svc.cs
  9. public string Add(string num1, string num2)
  10. {
  11. int res = Convert.ToInt32(num1) + Convert.ToInt32(num2);
  12. return "Result is : " + res.ToString();
  13. }
Step 2(Creating website)

Default.aspx
  1. <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
  2. <!DOCTYPE html>
  3. <html
  4. xmlns="http://www.w3.org/1999/xhtml">
  5. <head runat="server">
  6. <title></title>
  7. </head>
  8. <body>
  9. <form id="form1" runat="server">
  10. Enter First Number
  12. <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
  13. <br />
  14. Enter Second Number
  15. <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
  16. <br />
  17. <asp:Button ID="btn_Add" runat="server" OnClick="btnAdd_Click" Text="Add" />
  18. </form>
  19. </body>
  20. </html>
Default.aspx.cs

Note: Add these namespaces

  1. using System.Net;
  2. using System.IO;
  3. using System.Runtime.Serialization;
  4. protected void btnAdd_Click(object sender, EventArgs e)
  5. {
  6. WebClient proxy = new WebClient();
  7. byte[] abc = proxy.DownloadData((new Uri("http://localhost:21269/Service1.svc/Add/" + TextBox1.Text + "/" + TextBox2.Text)));
  8. Stream strm = new MemoryStream(abc);
  9. DataContractSerializer obj = new DataContractSerializer(typeof(string));
  10. string result = obj.ReadObject(strm).ToString();
  11. Response.Write(result);
  12. }

Thanks...
