I'm setting up audit log for web api. Here i would like to remove password property from json string because of security reason. I don't want to log login password for login API.

Json/Request Payload:

{"code":"medics1","username":"admin","password":"password"}

I tried with below code:

var payload = JArray.Parse(objQueue.payload);
payload.Remove("password");

You are closed to your goal. You need just one little change in your code.

You are using JArray and this is use for parsing json that start and end with [...] not for {...}

And your json is a JObject that means its start and end with {...}

So just use JObject instead of JArray and then it will works

string json = @"{ 'code':'medics1','username':'admin','password':'password'}";

JObject jObject = JObject.Parse(json);

jObject.Remove("password");

string outputJson = jObject.ToString();

Output: (From Debugger)

JavaScript, How to Convert JS Object to JSON String in JQuery/Javascript? PranchalKatiyar. Check out this Author's contributed articles. If you like� I want to remove all the JSONObject that contains "publishtype": "UNPUBLISHED” and my JSONArray only contains those objects that have "publishtype": "PUBLISHED". I am using classes from org.json library for JSON Parsing.

You should use jobject parse here. Below code from newtonsoft site should be helpful

string json = @"{
    'channel': {
     'title': 'Star Wars',
     'link': 'http://www.starwars.com',
     'description': 'Star Wars blog.',
     'obsolete': 'Obsolete value',
     'item': []
    }
 }";

JObject rss = JObject.Parse(json);
JObject channel = (JObject)rss["channel"];
channel.Property("obsolete").Remove();

You do not have named object, hence you can directly call

rss.Property("password").Remove();

Another alternative aproach is to deserialize into a class which ignores password property and then serialize it again.

Hope this helps.

Modifying JSON, string json = @"{ 'channel': { 'title': 'Star Wars', 'link': 'http://www.starwars.com', ' description': 'Star Wars blog.', 'obsolete': 'Obsolete value', 'item': [] } }"; JObject rss � Since the deserializer defined above will parse the JSON into the Jackson tree model and then serialize it back to a string, the result may not be equal to the original content of the payload property. If you want to keep the spaces, tabs, line breaks and the order of the JSON properties, have a look at the following implementation, which won

You were almost correct, just you have to deserialize into an object instead of an array based on your JSON string.

string str = @"{'code':'medics1','username':'admin','password':'password'}";
JObject j = JsonConvert.DeserializeObject<JObject>(str);
j.Remove("password");
Console.WriteLine(j.ToString(Formatting.Indented));

Outputting:

{
  "code": "medics1",
  "username": "admin"
}
