SqlParameter[] sp = new SqlParameter[]
\x05{
new SqlParameter("@id",model.id),

}
与 传参改成 new SqlParameter("id",model.id),
new SqlParameter("name",model.name)有什么区别?注意@!

@ID 是参数值
好比 select * from users where id=@ID
你传参数
SqlParameter[] parameters = {new SqlParameter("@ID",SqlDbType.Int,4)};
parameters[0].Value = ID;此ID 是变量传值给@ID
