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

Using the BoxDataAdapter

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 BoxDataAdapter is slower than the BoxDataReader because the Fill method needs to retrieve all data from the data source before returning.

The following example selects the Id and Name columns of the Files table:

C#

string connectionString = "InitiateOAuth=GETANDREFRESH;";

using (BoxConnection connection = new BoxConnection(connectionString)) {
  BoxDataAdapter dataAdapter = new BoxDataAdapter(
  "SELECT Id, Name FROM Files", connection);

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

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

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

VB.NET

Dim connectionString As String = "InitiateOAuth=GETANDREFRESH;"

Using connection As New BoxConnection(connectionString)
  Dim dataAdapter As New BoxDataAdapter("SELECT Id, Name FROM Files", connection)

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

  Console.WriteLine("Contents of Files.")

  For Each row As DataRow In table.Rows
    Console.WriteLine("{0}: {1}", row("Id"), row("Name"))
  Next
