Deserialize Json object's property in C#

To detect if a deserialized object is missing a property using Json.NET, you can use the JsonSerializerSettings.MissingMemberHandling property. This property specifies how Json.NET should handle missing members during deserialization. To detect missing members, you can set this property to MissingMemberHandling.Error and handle the resulting JsonSerializationException:

string json = "{\"Name\":\"John\"}";
JsonSerializerSettings settings = new JsonSerializerSettings
{
    MissingMemberHandling = MissingMemberHandling.Error
};

try
{
    MyClass obj = JsonConvert.DeserializeObject<MyClass>(json, settings);
}
catch (JsonSerializationException ex)
{
    // handle missing member exception here
}

To ignore missing properties during deserialization, you can set the MissingMemberHandling property to MissingMemberHandling.Ignore:

string json = "{\"Name\":\"John\"}";
JsonSerializerSettings settings = new JsonSerializerSettings
{
    MissingMemberHandling = MissingMemberHandling.Ignore
};

MyClass obj = JsonConvert.DeserializeObject<MyClass>(json, settings);

To show a different property name during deserialization, you can use the JsonPropertyAttribute to specify the JSON property name for a .NET property:

public class MyClass
{
    [JsonProperty("name")]
    public string Name { get; set; }
}

string json = "{\"name\":\"John\"}";
MyClass obj = JsonConvert.DeserializeObject<MyClass>(json);

In this example, the JsonProperty attribute is used to map the Name property to the name JSON property.
