Basic Console Application (C#)

Basic Console Application (C#)

This Console application uses default input parameters and a hard-coded query string to demonstrate the basic functionality of the Live Search Web Service API.

Tip
You can use this sample application to run any of the examples in the API Reference by copying the example code (using the Copy Code button in the topic) and pasting it into the sample application between the comments. In each case, you will need to use your own AppID and rebuild the sample application to run the example code.

To set up the project in Microsoft Visual Studio .NET 2005

Open Microsoft Visual Studio .NET 2005 and, from the File menu, choose New | Project. The New Project dialog box appears.
In the Project types pane, choose Visual C# and then choose Windows.
In the Templates pane, choose Console Application.
Type the name of the project, ConsoleSampleWebSearch, in the Name text box and click OK. Visual Studio creates a new project.
In the Solution Explorer, right-click References and, from the pop-up menu, select Add Web Reference.
Type the following address in the URL text box: http://soap.search.msn.com/webservices.asmx?wsdl.
Click Go.
In the Web reference name text box, type LiveSearch and click Add Reference.

To add the source code to the project

Replace the source code in the file Program.cs with the source code in the Example section. To do this:
1. Click Copy Code to place the code in the Windows Clipboard.
2. Open Program.cs from the Solution Explorer, place your cursor anywhere in the file, and press Ctrl + A.
3. Press Ctrl + V to paste the code into the Visual Studio source file, overwriting the template-generated code.
Search for and replace the text YOUR_APP_ID_GOES_HERE with the AppID you generated from the Developer Provisioning System.
Press F5 to run the application in Debug mode.

Requirements

Microsoft Visual Studio .NET 2005 or Microsoft Visual C# .NET 2005.
Internet connection.
Application ID. (See Getting Started with the Live Search API for more information on obtaining an AppID for use with the Live Search Web Service.)

Demonstrates

A basic Web search using the keywords live search and default input parameters.
