OracleデータベースのC＃でデータセットを埋める方法

これがsystem.data.oracleclientの例ですhttp://msdn.microsoft.com/en-us/library/system.data.oracleclient.oracledataadapter%28v=vs.71%29.aspx（この例は1.1ですが、 2.0と同じ）

（リンクからの抜粋）

OracleConnection conn = new OracleConnection("Data Source=Oracle8i;Integrated Security=yes");
Conn.Open;
OracleCommand cmd = conn.CreateCommand();
cmd.CommandText = "sp_pkg.getdata";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new OracleParameter("a1", OracleType.Cursor)).Direction = ParameterDirection.Output;
cmd.Parameters.Add(new OracleParameter("a2", OracleType.Cursor)).Direction = ParameterDirection.Output;
DataSet ds = new DataSet();
OracleDataAdapter adapter = new OracleDataAdapter(cmd);
adapter.Fill(ds);

ODP（推奨）の例を次に示します。http：//www.oracle.com/technology/sample_code/tech/windows/odpnet/DSPopulate/ViewProducts.cs.html

//Instantiate OracleDataAdapter to create DataSet
productsAdapter = new OracleDataAdapter();

//Fetch Product Details
productsAdapter.SelectCommand = new OracleCommand("SELECT " +
                                                  "Product_ID , " +
                                                  "Product_Name , " +
                                                  "Product_Desc , " +
                                                  "Category, " +
                                                  "Price " +
                                                  "FROM Products",conn);

//Instantiate DataSet object
productsDataSet = new DataSet("productsDataSet");

//Fill the DataSet with data from 'Products' database table
productsAdapter.Fill(productsDataSet, "Products");

//setting 'productsDataSet' as  the datasouce and 'Products' table
//as the table to which the 'productsDataGrid' is Bound.
productsDataGrid.SetDataBinding(productsDataSet,"Products");
