What is the Bing Search API?

The Bing Application Programming Interface (API) enables developers to programmatically submit queries to and retrieve results from the Bing Search Engine. Bing also introduces a superior service for developers. It encourages developers to use their Search API into their own application.

Here, I am going to demonstrate you How to Use Bing Search API in our application.

I’ll discuss about to Integrate Bing Search API from very basics (from registering on

Windows Azure Marketplace to Using .Net Class Library to the application).

To use Bing Search API, firstly you need to register on Windows Azure Marketplace.

Now you are a registered member of Windows Azure market place. You can

subscribe to data applications. In order to use BING API in your application, you

must obtain your Account Key, in the previous version of Bing you were required an

API key, the current version uses Account Key instead.

Once you logged in to the Windows Azure market place, you can see “My Account”

in the top menu, from the Top menu; go to “My Account” Section.

1.      Open Visual Studio 2010 >File >New >Website >Under Template Section Choose ASP.NET Empty Web Site, Choose Location to save it and Provide name to it. Click OK.

2.      Now, you have to add the Downloaded .Net C# Class Library to your Project. You can do this task by Right Clicking on Solution Explorer > Add Existing Item >Browse the Location of File > Add it in your Project.

4.      Now, add an ASP WEB Form to your project by Right Clicking on Solution Explorer >Add New Item.

Create the Following UI for the Web Page you have added.

Integrate Bing Search API in ASP.NET Web Form

In above UI, I have taken a TextBox Control for Entering Search Term into it, a

Button Control and a GridView Control to show the search result.

In GridView I have added three Template Control i.e., a Label Control for Displaying

the Title, a Hyperlink Control which will enable user to Navigate to the Page and

again a Label Control to show the description of the site. I have bind all these

Controls to the Data Source using

'<%# Bind("<ColumnName>") %>

Here is the code snippet that I have written for the Default.aspx page.
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <form id="form1" runat="server">
        <table style="width:100%;">
                <td align="center" bgcolor="#99CCFF" colspan="2">
                    <asp:Label ID="Label1" runat="server" Font-Bold="True" Font-Names="Georgia"

                            <br />
                            <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%#Bind("Url") %>'><%#Eval("Url") %></asp:HyperLink>
                            <br />

                            <br />
                            <br />

5.      Now, Switch to Default.aspx.cs file.

Add Following Code for Button Click Event Handler.

//Add the namespace "Using Bing;"

    protected void Button1_Click(object sender, EventArgs e)
        var objBing = new Bing.BingSearchContainer(new Uri("https://api.datamarket.azure.com/Bing/Search"));
        //Replace this Account Key with you Account Key
        var accountKey = "EMdPzpSl/qTbvz6/ScfE5sFLzuxNfU/crNSmIYjQDes=";
        //Passing the Credintial
        objBing.Credentials = new System.Net.NetworkCredential(accountKey, accountKey);
        //Following Line is used to get the Search Result as DataSource.
        var webResult = objBing.Web(txtSearch.Text.ToString(),null,null,null,null,null,null,null);
        //Binding the Resultant DataSource to the GridView
        GridViewSearchResult.DataSource = webResult;
 Now run you project. Following Window will appear in front of you.
