Using GetSchemaTable() to retrieve only column names

Is it possible to use GetSchemaTable() to retrieve only column names?

I have been trying to retrieve Column names (only) using this method, is it possible.

  DataTable table = myReader.GetSchemaTable();

  foreach (DataRow myField in table.Rows)
  {
      foreach (DataColumn myProperty in table.Columns)
      {
          fileconnectiongrid.Rows.Add(myProperty.ColumnName + " = " 
                            + myField[myProperty].ToString());
      }
  }

This code retrieves a lot of table data unwanted, I only need a list containing column names!:
