Serializing multiple DateTime properties in the same class using different formats for each one

Question

I have a class with two DateTime properties. I need to serialize each of the properties with a different format. How can I do it? I tried:

JsonConvert.Serial

You can create a custom date class that inherits the IsoDateTimeConverter and pass a format on the constructor. On the attributes, you can specify which format corresponds to each property. See code below:

public class LoginResponse
{
    [JsonProperty("access_token")]
    public string AccessToken { get; set; }
    [JsonProperty("token_type")]
    public string TokenType { get; set; }
    [JsonProperty("expires_in")]
    public DateTime ExpiresIn { get; set; }
    [JsonProperty("userName")]
    public string Username { get; set; }
    [JsonConverter(typeof(CustomDateFormat), "EEE, dd MMM yyyy HH:mm:ss zzz")]
    [JsonProperty(".issued")]
    public DateTime Issued { get; set; }
    [JsonConverter(typeof(CustomDateFormat), "MMMM dd, yyyy")]
    [JsonProperty(".expires")]
    public DateTime Expires { get; set; }
}

public class CustomDateFormat : IsoDateTimeConverter
{
    public CustomDateFormat(string format)
    {
        DateTimeFormat = format;
    }
}
