.NET NewtonSoft JSON deserialize map to a different property name

Question

I have following JSON string which is received from an external party.

{
   \"team\":[
      {
         \"v1\":\"\",
         \"attributes\":{
            \"

Adding to Jacks solution. I need to Deserialize using the JsonProperty and Serialize while ignoring the JsonProperty (or vice versa). ReflectionHelper and Attribute Helper are just helper classes that get a list of properties or attributes for a property. I can include if anyone actually cares. Using the example below you can serialize the viewmodel and get "Amount" even though the JsonProperty is "RecurringPrice".

    /// 

    /// Ignore the Json Property attribute. This is usefule when you want to serialize or deserialize differently and not 
    /// let the JsonProperty control everything.
    /// 
    /// 
    public class IgnoreJsonPropertyResolver : DefaultContractResolver
    {
        private Dictionary PropertyMappings { get; set; }

        public IgnoreJsonPropertyResolver()
        {
            this.PropertyMappings = new Dictionary();
            var properties = ReflectionHelper.GetGetProperties(false)();
            foreach (var propertyInfo in properties)
            {
                var jsonProperty = AttributeHelper.GetAttribute(propertyInfo);
                if (jsonProperty != null)
                {
                    PropertyMappings.Add(jsonProperty.PropertyName, propertyInfo.Name);
                }
            }
        }

        protected override string ResolvePropertyName(string propertyName)
        {
            string resolvedName = null;
            var resolved = this.PropertyMappings.TryGetValue(propertyName, out resolvedName);
            return (resolved) ? resolvedName : base.ResolvePropertyName(propertyName);
        }
    }

Usage:

        var settings = new JsonSerializerSettings();
        settings.DateFormatString = "YYYY-MM-DD";
        settings.ContractResolver = new IgnoreJsonPropertyResolver();
        var model = new PlanViewModel() {Amount = 100};
        var strModel = JsonConvert.SerializeObject(model,settings);

Model:

public class PlanViewModel
{

    /// 

    ///     The customer is charged an amount over an interval for the subscription.
    /// 
    [JsonProperty(PropertyName = "RecurringPrice")]
    public double Amount { get; set; }

    /// 

    ///     Indicates the number of intervals between each billing. If interval=2, the customer would be billed every two
    ///     months or years depending on the value for interval_unit.
    /// 
    public int Interval { get; set; } = 1;

    /// 

    ///     Number of free trial days that can be granted when a customer is subscribed to this plan.
    /// 
    public int TrialPeriod { get; set; } = 30;

    /// 

    /// This indicates a one-time fee charged upfront while creating a subscription for this plan.
    /// 
    [JsonProperty(PropertyName = "SetupFee")]
    public double SetupAmount { get; set; } = 0;


    /// 

    /// String representing the type id, usually a lookup value, for the record.
    /// 
    [JsonProperty(PropertyName = "TypeId")]
    public string Type { get; set; }

    /// 

    /// Billing Frequency
    /// 
    [JsonProperty(PropertyName = "BillingFrequency")]
    public string Period { get; set; }


    /// 

    /// String representing the type id, usually a lookup value, for the record.
    /// 
    [JsonProperty(PropertyName = "PlanUseType")]
    public string Purpose { get; set; }
}
