How Can I Deserialize JSON Properties Without Serializing Them Using Json.Net?

Use Json.Net to deserialize properties without serializing

In some cases, you may need to deserialize properties from a serialized JSON object, but don't want to write them back when serializing. Here's how to achieve this using Json.Net.

Method 1: ShouldSerialize method

Json.Net allows you to conditionally serialize properties by defining the ShouldSerialize method in the class. Create a ShouldSerializeBlah() method (where Blah is the property you don't want to serialize) and make it always return false:

<code>public bool ShouldSerializeObsoleteSetting()
{
    return false;
}</code>

Method 2: Use JObject to operate JSON

Use JObject.FromObject to load objects into JObject. Remove unnecessary attributes before writing to JSON:

<code>JObject jo = JObject.FromObject(config);
jo["ObsoleteSetting"].Parent.Remove();
json = jo.ToString();</code>

Method Three: Attribute Abuse

Apply the [JsonIgnore] attribute to properties you do not want to serialize. Define a private property setter with the same type and name as the original property and apply the [JsonProperty] attribute to it using the same JSON name:

<code>[JsonIgnore]
public Fizz ObsoleteSetting { get; set; }

[JsonProperty("ObsoleteSetting")]
private Fizz ObsoleteSettingAlternateSetter
{
    set { ObsoleteSetting = value; }
}</code>

By using one of the above methods, you can selectively exclude properties from serialization while still allowing deserialization.
