Find keyword in JSON-Object & Spelling checker using C#

Question

Dear Sir or Madam,
I have a question about finding the keywords in Json object after reading the file (I read the file like this:

            string path = @"path";
            var JObject = JsonConvert.DeserializeObject(File.ReadAllText(path));
            Console.WriteLine(JObject);).

I would like to solve this with try and catch to check if the keywords exist and also I would like to check the spelling of the keywords after checking the keywords for "is there or not". I have already created the required classes for it (the class looks like this:

        public class Driver
        {
        public string type;
        public int speed;
        public string label;
        public string name;
        public int id;
        public string startpoint;
        public string midPoint;
        public string endpoint;
        }

--> For example I want to find the keyword Speed in the json object and then I want to make sure that the keyword does not have any misspellings like Sped instead of Speed.

Do you have an idea how I can do this best. Thanks in advance.

With kind regards,
Sela

Writing a decent spell checker requires a decent dictionary and logic, you should consider looking at existing ones e.g.

It is probably easier to look in json in file instead of looking in object for key word

         string path = @"path";
         string json = File.ReadAllText(path);
         bool hasKeyWord = json.Contains("MyKeyWord");

var JObject = JsonConvert.DeserializeObject(json);

You could do something like this if you want to let the framework parse the JSON for you & you just need to check the properties:

as you are using newtonsoft. you could just use the standard json schema validation support rather than trying to roll your own:
