我有一个JSON字符串,需要反序列化为一个对象.

这是我尝试过的:

课程:

public class trn
{
    public string visited_date { get; set; }
    public string party_code { get; set; }
    public string response { get; set; }
    public string response_type { get; set; }
    public string time_stamp { get; set; }
    public string trans_id { get; set; }
    public double total_amount { get; set; }
    public double discount { get; set; }
}

json字符串:

string json = "{\"trn\":{\"visited_date\":\"2015-04-05\",\"party_code\":\"8978a1bf-c88b-11e4-a815-00ff2dce0943\",\"response\":\"Reason 5\",\"response_type\":\"NoOrder\",\"time_stamp\":\"2015-04-05 18:27:42\",\"trans_id\":\"8e15f00b288a701e60a08f968a42a560\",\"total_amount\":0.0,\"discount\":0.0}}";

trn model2 = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<trn>(json);

并使用json.net

trn model = …

我有c#对象,我需要在javascript中引用默认填充.目前我正在维护两个不可维护的不同对象.

例如(为演示目的而简化):

C#

public class Text
{
     public string Name {get;set;}
}

JSON

{
     'text': {
          name: undefined
     }
}

我知道有很多方法可以实现这一目标,但想知道是否有人有推荐的解决方案.谢谢!

public async Task<WalletTrans> getCredits(int id) 
{
    var credit = await _context.walletTrans.ToAsyncEnumerable().Where(r => r.Id == id).Sum(s => s.quantity);
    return credit;
}

我上面的代码使用的是C#.net核心,据说可以返回表中字段的总和.

但我有这个错误.

"无法将类型'decimal'隐式转换为'ProjectName.Models.ModelName'[ProjectName]"

我有一个数据样本,如下所示.

{
    "ditems": [
        {
            "type": "ditem",
            "name": "webmet.com",
            "ditem": 0,
            "links": [
                "www.abc.com/a",
                "www.sempo.org/"
                ]
        },
        {
            "type": "ditem",
            "name": "webmet.com/who-we-are/careers",
            "ditem": 2,
            "links": [
                "http://www.tele12.com/about",
                "http://tele12.com/life-at-teletech-en-US/about-teletech/"
            ]
        }
    ],
    "themes": [
        {
            "type": "theme",
            "name": "http://searchm.com/isr/agenda",
            "description": "",
            "slug": "http://searchm.com/isr/agenda-2"
        },
        {
            "type": "theme",
            "name": "http://www.sempo.org/",
            "description": "",
            "slug": "http://www.sempo.org/-2"
        }

    ]
}

这是我的代码

 var InternalURLList = dtInternalURL.AsEnumerable().Select(c => c.Field<string>("URL")).Distinct().ToList();

            StringBuilder sb = new StringBuilder();
            StringBuilder ThemeSb = new StringBuilder();
            sb.Append("{\"ditems\":[");

            if (InternalURLList.Count > 0)
            {
                for (int …
