範例

下列程式碼範例示範如何使用 控制項和簡單的Web Form頁面將資料插入資料庫中 SqlDataSource 。 資料表中的目前資料會顯示在 控制項中 DropDownList 。 您可以在控制項中 TextBox 輸入值，然後按一下 [ 插入 ] 按鈕，以新增記錄。 按一下 [ 插入 ] 按鈕時，指定的值會插入資料庫中，並 DropDownList 重新整理 。

備註

InsertCommand如果屬性包含參數化 SQL 查詢， InsertParameters 集合會包含任何 Parameter 對應至 SQL 字串中參數預留位置的物件。

視 ADO.NET 提供者而定，集合中的 InsertParameters 參數順序可能很重要。 System.Data.OleDb和 System.Data.Odbc 提供者會根據參數出現在參數化 SQL 查詢中的順序，關聯集合中的參數。 System.Data.SqlClient提供者是控制項的預設 ADO.NET 提供者 SqlDataSource ，會比對參數的名稱與 SQL 查詢中的預留位置別名，使集合中的參數產生關聯。 如需參數化 SQL 查詢和命令的詳細資訊，請參閱 搭配 SqlDataSource 控制項使用參數。
