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

Using the BasecampDataAdapter

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 BasecampDataAdapter is slower than the BasecampDataReader 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 Projects table:

C#

string connectionString = "InitiateOAuth=GETANDREFRESH;AccountId=1234567;Schema=V3;ProjectId=abcd1234";

using (BasecampConnection connection = new BasecampConnection(connectionString)) {
  BasecampDataAdapter dataAdapter = new BasecampDataAdapter(
  "SELECT Id, Name FROM Projects", connection);

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

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

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

VB.NET

Dim connectionString As String = "InitiateOAuth=GETANDREFRESH;AccountId=1234567;Schema=V3;ProjectId=abcd1234"

Using connection As New BasecampConnection(connectionString)
  Dim dataAdapter As New BasecampDataAdapter("SELECT Id, Name FROM Projects", connection)

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

  Console.WriteLine("Contents of Projects.")

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