注解
InsertCommand如果 属性包含参数化 SQL 查询，则InsertParameters集合包含与 SQL 字符串中的参数占位符对应的任何Parameter对象。
根据 ADO.NET 提供程序，集合中 InsertParameters 参数的顺序可能很重要。 System.Data.OleDb和 System.Data.Odbc 提供程序根据参数化 SQL 查询中参数的显示顺序关联集合中的参数。 System.Data.SqlClient提供程序是控件的默认 ADO.NET 提供程序SqlDataSource，通过将参数的名称与 SQL 查询中的占位符别名匹配来关联集合中的参数。 有关参数化 SQL 查询和命令的详细信息，请参阅 对 SqlDataSource 控件使用参数。
