Question

我有下面的JSON。反序列化时，responseHeader和response可以正常工作，但highlighting不能正常工作。

问题正在突出显示数据，如下所示，_text_为空。我想将两个值都存储在两个字段中。问题是第一部分没有任何常量字段名称。

1. C:\\TestArea..........
2. _text_

  "highlighting":{ 
        "C:\\TestArea\\Destination\\SUP000011\\ATM-1B4L2KQ0ZE0-0001\\SoS_Update_2018_06_04_pram.pptx":{
          "_text_":["\nSCRUM of SCRUMs S4-W1 \n AXP Internal \n 4-<em>Jun</em>-18 \n \n slide-master-content   \n \n  \n slide-notes   \n 4-<em>Jun</em>"]},

JSON：

{
    "responseHeader": {
        "status": 0,
        "QTime": 115,
        "params": {
            "q": "\"John\"",
            "hl": "on",
            "hl.simple.post": "</em>",
            "start": "0",
            "rows": "10000",
            "hl.simple.pre": "<em>"
        }
    },
    "response": {
        "numFound": 10,
        "start": 0,
        "docs": [{
            "domain": ["FIU/FCRU"],
            "id": "C:\\TestArea\\Destination\\SUP000011\\ATM-1B4L2KQ0ZE0-0001\\SoS_Update_2018_06_04_pram.pptx"

        }]
    },
    "highlighting": {
        "C:\\TestArea\\Destination\\SUP000011\\ATM-1B4L2KQ0ZE0-0001\\SoS_Update_2018_06_04_pram.pptx": {
            "_text_": ["\nSCRUM of SCRUMs S4-W1 \n AXP Internal \n 4-<em>Jun</em>-18 \n \n slide-master-content   \n \n  \n slide-notes   \n 4-<em>Jun</em>"]
        },
        "C:\\TestArea\\Destination\\SUP000005\\F-3-20150505-0028\\tt.csv": {
            "_text_": [",NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL\r\n930,<em>John</em> Ferguson,NULL,2015-06-30 15:27:04.677,test.test"]

        }
    }
}

我的数据模型和代码：

public class RootObject
{
    public ResponseHeader responseHeader { get; set; }
    public Response response { get; set; }
    public Highlighting highlighting { get; set; }
} 
public class Highlighting
{   
    public List<string> _text_ { get; set; }
}

var outObject = JsonConvert.DeserializeObject<RootObject>(jsonString, new JsonSerializerSettings() { TypeNameHandling = TypeNameHandling.Auto });

对于string(from:to:)属性，使用import Foundation let calendar = Calendar.current let startDate = calendar.date(from: DateComponents(year: 2010, month: 11, day: 22))! let endDate = calendar.date(from: DateComponents(year: 2015, month: 5, day: 1))! let formatter = DateComponentsFormatter() formatter.unitsStyle = .full formatter.allowedUnits = [.year, .month, .day] let string = formatter.string(from: startDate, to: endDate)! print(string) // prints: 4 years, 5 months, 9 days就像这样：

@IBAction func middleFinderButton(_ sender: Any) {

    let totalLatitude = mapView.annotations.reduce(0) { $0 + $1.coordinate.latitude }

    let totalLongitude = mapView.annotations.reduce(0) { $0 + $1.coordinate.longitude }

    let averageLatitude = totalLatitude/Double(mapView.annotations.count)

    let averageLongitude = totalLongitude/Double(mapView.annotations.count)

    let centerPoint = MKPointAnnotation()

    centerPoint.coordinate.latitude = averageLatitude
    centerPoint.coordinate.longitude = averageLongitude

    mapView.addAnnotation(centerPoint)
}

为什么这样做？如果我像这样简化highlighting的值：

Dictionary<string, Highlighting>

我们可以看到它是一个JSON对象，其变量属性名称的值具有固定的模式。 Json.NET支持在字典之间进行序列化。有关详细信息，请参见Deserialize a Dictionary。
