------解决思路----------------------
class A
{ public string code{get;set;}
public string message{get;set;}
public List<B> data{get;set;}
}
class B
{
public order orderInfo{get;set;}
public  supplier supplierInfo{get;set;}
public List<Item> itemList{get;set;}
}
class order 
{
public int orderId{get;set;}
//其它属性补全
}
//supplier和item一样定义
