Step 3
Write the code in the code behind file like this.
- using LitJson;
- using System;
- using System.Collections.Generic;
- using System.IO;
- using System.Linq;
- using System.Net;
- using System.Web;
- using System.Web.UI;

- {
-
- }
-
- protected void btnSearch_Click(object sender, EventArgs e)
- {
- PostOfficeResult postOfficeResult = null;
- try
- {
- string userAuthenticationURI = "http://postalpincode.in/api/pincode/" + txtPinCode.Text.Trim();
-
- if (!string.IsNullOrEmpty(userAuthenticationURI))
- {
- HttpWebRequest request = (HttpWebRequest)WebRequest.Create(userAuthenticationURI);
- request.Method = "GET";
- request.ContentType = "application/json";
- WebResponse response = request.GetResponse();
- using (var reader = new StreamReader(response.GetResponseStream()))
- {
- var ApiStatus = reader.ReadToEnd();
- JsonData data = JsonMapper.ToObject(ApiStatus);

-
- }
- if (postOfficeResult != null)
- {

- grdAreaPostOffice.DataBind();
- }
- else
- {
- lblMessage.Text = data["Message"].ToString();
- }
- }
