Need a string JSON Validator [duplicate]

Answer 1

The simplest solution would be to write a function which calls JObject.Parse and returns false if it throws the exception.

Answer 2

A working code snippet

public bool isValidJSON(string json)
{
    try
    {
        JToken token = JObject.Parse(json);
        return true;
    }
    catch(Exception ex)
    {
        return false;
    }
}

Answer 3

Use JContainer.Parse(str) method to check if the str is a valid Json. If this throws exception then it is not a valid Json.

JObject.Parse - Can be used to check if the string is a valid Json object
JArray.Parse - Can be used to check if the string is a valid Json Array
JContainer.Parse - Can be used to check for both Json object & Array
