The CData ADO.NET Provider for Google Search implements two ADO.NET interfaces you can use to retrieve data from Google Search: GoogleSearchDataAdapter and GoogleSearchDataReader objects. Whereas GoogleSearchDataAdapter objects retrieve a single result set of all the data that matches a query, GoogleSearchDataReader objects fetch data in subset increments as needed.

Using the GoogleSearchDataAdapter

Use the adapter's Fill method to retrieve data from the data source. An empty DataTable instance is passed as an argument to the Fill method. When the method returns, the DataTable instance is populated with the queried data. Note that the GoogleSearchDataAdapter is slower than the GoogleSearchDataReader because the Fill method needs to retrieve all data from the data source before returning.

The following example selects the DisplayLink and Title columns of the WebSearch table:

C#

string connectionString = "ApiKey=abc123; CustomSearchID=def456;";

using (GoogleSearchConnection connection = new GoogleSearchConnection(connectionString)) {
  GoogleSearchDataAdapter dataAdapter = new GoogleSearchDataAdapter(
  "SELECT DisplayLink, Title FROM WebSearch WHERE SearchTerms = 'Fantastic Four'", connection);

  DataTable table = new DataTable();
  dataAdapter.Fill(table);

  Console.WriteLine("Contents of WebSearch.");

  foreach (DataRow row in table.Rows) {
    Console.WriteLine("{0}: {1}", row["DisplayLink"], row["Title"]);
  }
}

VB.NET

Dim connectionString As String = "ApiKey=abc123; CustomSearchID=def456;"

Using connection As New GoogleSearchConnection(connectionString)
  Dim dataAdapter As New GoogleSearchDataAdapter("SELECT DisplayLink, Title FROM WebSearch WHERE SearchTerms = 'Fantastic Four'", connection)

  Dim table As New DataTable()
  dataAdapter.Fill(table)

  Console.WriteLine("Contents of WebSearch.")

  For Each row As DataRow In table.Rows
    Console.WriteLine("{0}: {1}", row("DisplayLink"), row("Title"))
  Next
End Using
