You can access the same column information about the results of a query that you can for table schemas. See Columns for the columns returned.

Retrieving Result Set Metadata

You can use the GetSchemaTable method of the BasecampDataReader to retrieve result set metadata. Call GetSchemaTable after calling ExecuteReader.

Each row of the DataTable describes a column in the query's result.

C#

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

using (BasecampConnection conn = new BasecampConnection(connectionString)) {
  BasecampCommand cmd = new BasecampCommand("SELECT * FROM Projects WHERE Id = 'MyId'", conn);
  BasecampDataReader rdr = cmd.ExecuteReader();
  DataTable schemaTable = rdr.GetSchemaTable();
  foreach (DataRow row in schemaTable.Rows) {
    foreach (DataColumn col in schemaTable.Columns) {
      Console.WriteLine("{0}: {1}", col.ColumnName, row[col]);
    }
  }
}

VB.NET

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

Using conn As New BasecampConnection(connectionString)
  Dim cmd As New BasecampCommand("SELECT * FROM Projects WHERE Id = 'MyId'", conn)
  Dim rdr As BasecampDataReader = cmd.ExecuteReader()
  Dim schemaTable As DataTable = rdr.GetSchemaTable()
  For Each row As DataRow In schemaTable.Rows
    For Each col As DataColumn In schemaTable.Columns
      Console.WriteLine("{0}: {1}", col.ColumnName, row(col))
    Next
  Next
End Using
