Google Hacks, 2nd Edition

Program Google in C# and .NET

Create GUI and console Google search applications with C# and the .NET framework.

The Google Web APIs Developer’s Kit includes a sample C# Visual Studio .NET (http://msdn.microsoft.com/vstudio/) project for a simple GUI Google search application (take a look in the dotnet/CSharp folder). The functional bits that you would probably find most interesting are in the Form1.cs code.

This hack provides basic code for a simple console Google search application similar in function (and, in the case of Java [Hack #97] , form, too) to those in Perl Hack #98 ], et al.

Tip

Compiling and running this hack requires that you have the .NET Framework (http://msdn.microsoft.com/netframework/downloads/updates/default.aspx) installed.

using System;
class Googly {
  static void Main(string[] args) {
    // Your Google API developer's key.
    string googleKey = "insert key here"; // Take the query from the command line. if( args.Length != 1 ) { Console.WriteLine("Usage: google.exe <query>"); return; } string query = args[0]; // Create a Google SOAP client proxy, generated by: // c:\> wsdl.exe http://api.google.com/GoogleSearch.wsdl GoogleSearchService googleSearch = new GoogleSearchService( ); // Query Google.
