Get values from a JSON string which has special tag in variable names C#


I get following JSON where i need to extract few data from it.

{  
 "id":"400xxtc200",
 "state":"failed",
 "name":"barbaPapa",
 "content-exception":"AccessDenied",
 "input-parameters":[  
    {  
       "value":{  
          "string":{  
             "value":"In"
          }
       },
       "type":"string",
       "name":"Operation",
       "scope":"local"
    },
    {  
       "value":{  
        "string":{  
           "value":"bila"
        }
     },
     "type":"string",
     "name":"VMName",
     "scope":"local"
  },
  {  
     "value":{  
        "string":{  
           "value":"txtc"
        }
     },
     "type":"string",
     "name":"PSUser",
     "scope":"local"
  },
  {  
     "value":{  
        "string":{  
           "value":"dv1"
        }
     },
     "type":"string",
     "name":"Datacenter",
     "scope":"local"
  },
  {  
     "value":{  
        "string":{  
           "value":"tpc"
        }
     },
     "type":"string",
     "name":"ServiceArea",
     "scope":"local"
  },
  {  
     "value":{  
        "string":{  
           "value":"103"
        }
     },
     "type":"string",
     "name":"SQN",
     "scope":"local"
  }
 ],
 "output-parameters":[  
  {  
     "type":"Array/string",
     "name":"tag",
     "scope":"local"
  },
  {  
     "value":{  
        "string":{  
           "value":"AccessDenied"
        }
     },
     "type":"string",
     "name":"Error",
     "scope":"local"
  }
 ]
}

I am trying to deserialize the JSON object in to a dynamic object which was successful.I'm using following C# code for the work

string responseText = reader.ReadToEnd();
dynamic in_values =    JsonConvert.DeserializeObject(responseText);
string state = in_values.state;

If you can see I have some tag names with hyphen in the JSON string.

For example output-parameters

I cant use the dot operate because then it will be as like follow

in_values.output-parameters;

How to extract those values from the JSON string.


Solution

  • You can use JsonProperty in this case.

    public class SampleClass
    {
        public string id { get; set; }
        public string state { get; set; }
        public string name { get; set; }
    
        [JsonProperty(PropertyName = "content-exception")]
        public string content_exception { get; set; }
        [JsonProperty(PropertyName = "input-parameters")]
        public List<InputParameter> input_parameters { get; set; }
        [JsonProperty(PropertyName = "output-parameters")]
        public List<OutputParameter> output_parameters { get; set; }
    }
    
    string json = File.ReadAllText("abc.txt");
    SampleClass obj = JsonConvert.DeserializeObject<SampleClass>(json);
    List<OutputParameter>  ls = obj.output_parameters;
