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

Using the AsanaDataAdapter

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

The following example selects the Id and WorkspaceId columns of the projects table:

C#

string connectionString = "InitiateOAuth=GETANDREFRESH;OAuthClientId=YourClientId;OAuthClientSecret=YourClientSecret;CallbackURL='http://localhost:33333'";

using (AsanaConnection connection = new AsanaConnection(connectionString)) {
  AsanaDataAdapter dataAdapter = new AsanaDataAdapter(
  "SELECT Id, WorkspaceId 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["WorkspaceId"]);
  }
}

VB.NET

Dim connectionString As String = "InitiateOAuth=GETANDREFRESH;OAuthClientId=YourClientId;OAuthClientSecret=YourClientSecret;CallbackURL='http://localhost:33333'"

Using connection As New AsanaConnection(connectionString)
  Dim dataAdapter As New AsanaDataAdapter("SELECT Id, WorkspaceId 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("WorkspaceId"))
  Next
End Using
