SqlDataAdapter对象其实相当于一个功能更强大的SqlCommand对象，SqlDataAdapter对象中包含了InsertCommand、DeleteCommand、UpdateCommand、SelectCommand...= new SqlDataAdapter(); //实例化SqlDataAdapter对象 sda.SelectCommand...= new SqlCommand("select * from Person", conn); //创建SqlDataAdapter对象的SelectCommand...]; //返回Person表的数据 } 这里需要注意的是，执行SelectCommand...的时候并不需要打开数据库连接对象，如果现在的连接是关闭的话，SelectCommand对象会自动打开数据库连接。

因为执行SqlDataAdapter已经打开了连接了 SqlParameter para0 = new SqlParameter("@name", "张三"); //给参数赋值，注意参数格式 sda.SelectCommand.Parameters.Add...(para0); //添加参数值 sda.SelectCommand.CommandType = CommandType.StoredProcedure; //指定执行类型为存储过程 try {
