Shows how to use DateOnly and TimeOnly with JSON.NET

JSON.NET and DateOnly/TimeOnly support

Code samples for Json.net which as of version 13.0.2 now supports DateOnly and TimeOnly. Three code samples are used to show interactions with Bogus and Microsoft.Data.SqlClient which is most likely used to work with json data.

Sample	Description
Sample1	Created a list of mocked people, serialize then deserialize with Json.net
Sample2	Same as Sample1 but uses Bogus NuGet package to create a list. Bogus just began support for DateOnly and TimeOnly with Json.net
DataOperations.Read	Reads DateOnly and TimeOnly from a SQL-Server database using a preview2 version of Microsoft.Data.SqlClient to seriale to json with Json.net

Requires

• Microsoft Visual Studio 2022 v17.4 or higher
• For the data read sample, SQLEXPRESS.

  }

Model

public class Container
{
    public int Id { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public DateOnly StartDate { get; set; }
    public TimeOnly StartTime { get; set; }
}

Mocked data

public class Mocked
{
    public  static List<Container> Container() =>
        new()
        {
            new()
            {
                Id = 1, 
                FirstName = "Karen", 
                LastName = "Payne", 
                StartDate = new DateOnly(2022,12,1), 
                StartTime = new TimeOnly(14,15)
            },
            new()
            {
                Id = 2, 
                FirstName = "May", 
                LastName = "Gallagher", 
                StartDate = new DateOnly(2022,12,11), 
                StartTime = new TimeOnly(16,0)
            }
        };
}

Get mocked data

var containers = Mocked.Container();

Serialize data

string json = JsonConvert.SerializeObject(containers, Formatting.Indented);

Deserialize data

var readContainers = JsonConvert.DeserializeObject<List<Container>>(json);
