Newtonsoft Serialize the List of Objects

Question

Is there a way to generate Serialized string of List <object> without any [ ]

we are doing serialization using following code

JsonConvert.SerializeObject(data)

[
  {
    "SessionId": "6d1ea52b-9f0c-4c32-835d-49e6db22efee",
    "ComponentName": "WebRole",
    "Message": "X"
  },
  {
    "SessionId": "6d1ea52b-9f0c-4c32-835d-49e6db22efee",
    "ComponentName": "WebRole",
    "Message": "Y"
  },
  {
    "SessionId": "6d1ea52b-9f0c-4c32-835d-49e6db22efee",
    "ComponentName": "WebRole",
    "Message": "Z"
  },
  {
    "SessionId": "6d1ea52b-9f0c-4c32-835d-49e6db22efee",
    "ComponentName": "WebRole",
    "Message": "XY"
  },
  {
    "SessionId": "6d1ea52b-9f0c-4c32-835d-49e6db22efee",
    "ComponentName": "WebRole",
    "Message": "XYZ",
    "Payload": "X>>1"
  }
]

Is there a way to remove above [ and ] , I have workaround to call Trim('[') and Trim(']') on serialize string. Is there any setting that come out of box from NewtonSoft which removes [ and ], also I dont want to make use of anonymous object.

1, 2, 3, 4 numbers after SessionId property are typos or they are present in your data ? — Manoj Choudhari

If you remove square brackets [] then your resultant JSON would be invalid. You can copy and paste your output json check here json2csharp.com — er-sho

we will not use deserialize function in C#. Instead, we will be ingesting data using some tool to insert into SQL/Data Store etc. — user145610

you would use Substring like => var newStr = jsonStr.Substring(1, jsonStr.Length - 1); — er-sho

If you tell newtonsoft to remove square brackets from json then It replies you that I am being programmed to produce only valid JSON, so how can I give you invalid JSON? So my suggestion is to go with string manipulation by using Trim or Substring — er-sho

No there's no way, if data is a collection then JsonConvert will return a JSON array. You can as you stated modify the output string by using Trim('[').Trim(']') but your JSON won't be valid.

@Sunil the question was "Is there a way to remove above ... ?" and my answer was no, I edit my answer to be more specific.

You're trying to use a List, not a Map/Dictionary, but you don't want the array behavior that comes with a List (but not a Dictionary/Map).

Get these straight and you'll find data MUCH easier to work with in many programming languages ;)
