Json.net how to serialize object as value

Question

I\'ve pored through the docs, StackOverflow, etc., can\'t seem to find this...

What I want to do is serialize/deserialize a simple value-type of object as a value, n

Answer 1

With the Cinchoo ETL - an open source library to parsing / writing JSON files, you can control the serialization of each object member via ValueConverter or with callback mechanism.

Method 1:

The sample below shows how to serialize 'SomeOuterObject' using member level ValueConverters

public class SomeOuterObject
{
    public string stringValue { get; set; }
    [ChoTypeConverter(typeof(ToTextConverter))]
    public IPAddress ipValue { get; set; }
}

And the value converter is

public class ToTextConverter : IChoValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return value;
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return value.ToString();
    }
}

Finally to serialize the object to file

using (var jr = new ChoJSONWriter("ipaddr.json")
    )
{
    var x1 = new SomeOuterObject { stringValue = "X1", ipValue = IPAddress.Parse("12.23.21.23") };
    jr.Write(x1);
}

And the output is

[
 {
  "stringValue": "X1",
  "ipValue": "12.23.21.23"
 }
]

Method 2:

This the alternative method to hook up value converter callback to 'ipValue' property. This approach is lean and no need to create value converter for just this operation.

using (var jr = new ChoJSONWriter("ipaddr.json")
    .WithField("stringValue")
    .WithField("ipValue", valueConverter: (o) => o.ToString())
    )
{
    var x1 = new SomeOuterObject { stringValue = "X1", ipValue = IPAddress.Parse("12.23.21.23") };
    jr.Write(x1);
}

Hope this helps.
