How to access Json element with the name "long" and "short"-CodePudding

I am trying to access a json element with the name "long", but VS gives an error, it detects it as a 16 bit signed integer. The other elements in Json I can access , except element "long" and "short". Is there a way around this?

var resultOpenPositions = JsonConvert.DeserializeObject<Root>(JsonopenPositions);
string ShrtLong = resultOpenPositions.positions[0].long.units; // long here gives error , vs detects it as a 16 bit signed integer

// Root myDeserializedClass = JsonConvert.DeserializeObject<Root>(myJsonResponse); 
    public class Long
    {
        public string averagePrice { get; set; }
        public string pl { get; set; }
        public string resettablePL { get; set; }
        public List<string> tradeIDs { get; set; }
        public string units { get; set; }
        public string unrealizedPL { get; set; }
    }

    public class Short
    {
        public string pl { get; set; }
        public string resettablePL { get; set; }
        public string units { get; set; }
        public string unrealizedPL { get; set; }
        public string averagePrice { get; set; }
        public List<string> tradeIDs { get; set; }
    }

    public class Position
    {
        public string instrument { get; set; }
        public Long @long { get; set; }
        public string pl { get; set; }
        public string resettablePL { get; set; }
        public Short @short { get; set; }
        public string unrealizedPL { get; set; }
    }

    public class Root
    {
        public string lastTransactionID { get; set; }
        public List<Position> positions { get; set; }
    }

here is the json part:

  "positions": [
    {
      "instrument": "EUR_USD",
      "long": {
        "units": "1",

        "unrealizedPL": "-0.0001"
      },
      "short": {
        "units": "0",
        "pl": "-543.3196",
        "resettablePL": "-543.3196",

        "unrealizedPL": "0.0000"
      },
      "pl": "-1620.5451",
      "resettablePL": "-1620.5451",
      "financing": "-51.8164",

      "dividendAdjustment": "0.0000",
      "guaranteedExecutionFees": "0.0000",
      "unrealizedPL": "-0.0001",
      "marginUsed": "0.0333"
    }
  ],
  "lastTransactionID": "17800"
}

CodePudding user response：

Prefix the call to the property name with an @:

Keywords are predefined, reserved identifiers that have special meanings to the compiler. They cannot be used as identifiers in your program unless they include @ as a prefix. For example, @if is a valid identifier, but if is not because if is a keyword.

string ShrtLong = resultOpenPositions.positions[0][email protected];

Alternativelly, configure the serializer to handle camel cased json elements while having Pascal cased properties on your model.

CodePudding user response：

IMHO, the best way is to use [JsonProperty] attribute. And you don't need 2 classes Long and Short, it would be enough just one.

Code

var resultOpenPositions = JsonConvert.DeserializeObject<Root(JsonopenPositions);
string ShrtLong = resultOpenPositions.positions[0].longPosition.units;

classes

  public class Root
    {
        public string lastTransactionID { get; set; }
        public List<Position> positions { get; set; }
    }

    public class Position
    {   
        public string pl { get; set; }
        public string instrument { get; set; }
        [JsonProperty("long")]
        public PositionPL longPosition { get; set; }
        [JsonProperty("short")]
        public PositionPL shortPosition { get; set; }
        public string resettablePL { get; set; }
        public string unrealizedPL { get; set; }
    }

  public class PositionPL
    { 
        public string pl { get; set; }
        public string averagePrice { get; set; }
        public string resettablePL { get; set; }
        public List<string> tradeIDs { get; set; }
        public string units { get; set; }
        public string unrealizedPL { get; set; }
    }
