休眠到 return Json with list

Question

我的 C# 代码有问题。我的 JSON 做不好。

我正在使用 NHIBERNATE 从我的 SQL 服务器连接和 select 数据。我想生成一个 JSON 里面有一个列表对象。需要你们的帮助。

NHibernate 代码：

 var query = (from partners in session.Query<Partners>()
             join partnerUsers in session.Query<PartnerUsers>() on partners.PartnerId equals partnerUsers.PartnerId
             where partners.PartnerId == partnerId
             select new Partnersss
             {
                 PartnerId = partners.PartnerId,
                 PartnerName = partners.Name,
                 PartnerUsers = new PartnerUsersss()
                 {
                     LoginId = partnerUsers.LoginId
                 }
             }).ToList<object>();
return query;

Class:

public class PartnerUsersss
{
    public int PartnerUserId { get; set; }
    public string LoginId { get; set; }
}

public class Partnersss
{
    public int PartnerId { get; set; }
    public string PartnerName { get; set; }
    public PartnerUsersss PartnerUsers { get; set; }
}

JSON 结果：

{
    "Data": "",
    "data": [{
        "PartnerId": 1,
        "PartnerName": "ExpressPay",
        "PartnerUsers": {
            "PartnerUserId": "0",
            "LoginId": "a@a.com"
        }
    }, {
        "PartnerId": 1,
        "PartnerName": "ExpressPay",
        "PartnerUsers": {
            "PartnerUserId": "0",
            "LoginId": "b@b.com"
        }
    }],
    "ResponseCode": "0",
    "ResponseMessage": "Successful"
}

但我希望能够生成此 JSON：

{
    "Data": "",
    "data": [{
        "PartnerId ": 1,
        "PartnerName": "ExpressPay ",
        "PartnerUsers": [{
            "partnerUserId": "0",
            "loginId": "a@a.com"
        }, {
            "partnerUserId": "0",
            "loginId": "b@b.com"
        }]
    }],
    "ResponseCode": "0",
    "ResponseMessage": "Successful"
}

我尝试将 List 与这种代码一起使用

PartnerUsers = new List<PartnerUsersss>

并更改 class。但是我得到一个错误

List does not contain a definition for LoginId

新 class:

public List<PartnerUsersss> PartnerUsers { get; set; }

您需要从查询中删除连接并修改您的查询，

var query = (from partners in session.Query<Partners>()
                     where partners.PartnerId == partnerId
                     let partnerUsers = (from pu in session.Query<PartnerUsers>()
                                         where pu.PartnerId == partners.PartnerId
                                         select pu).ToList()
                     select new Partnersss
                     {
                         PartnerId = partners.PartnerId,
                         PartnerName = partners.Name,
                         PartnerUsers = partnerUsers
                     }).ToList();

您需要将 PartnerUsers 属性的类型更改为列表，

public List<PartnerUsersss> PartnerUsers { get; set; }
