Examples

JsonNamingPolicyExtensions provides the DefaultOrConvertName extension method that applies a JsonNamingPolicy to a property name or returns it unchanged when the policy is null. This example applies JsonNamingPolicy.CamelCase to "OrderDate", producing "orderDate", and demonstrates that a null policy returns the name unaltered. Key steps include calling DefaultOrConvertName directly on a policy instance and using it within a JsonSerializerOptions configuration. Console output confirms "orderDate" for the camelCase transformation and "OrderDate" for the null policy case, and "shippingAddress" when sourced from serializer options.

public class JsonNamingPolicyExtensionsExample
{
    public static void Main()
    {
        // Apply camelCase naming policy
        JsonNamingPolicy camelCase = JsonNamingPolicy.CamelCase;
        string camelName = camelCase.DefaultOrConvertName("OrderDate");
        Console.WriteLine(camelName); // Output: "orderDate"

        // When policy is null, the name is returned unaltered
        string unchanged = ((JsonNamingPolicy)null).DefaultOrConvertName("OrderDate");
        Console.WriteLine(unchanged); // Output: "OrderDate"

        // Useful when working with configurable naming policies
        JsonSerializerOptions options = new JsonSerializerOptions
        {
            PropertyNamingPolicy = JsonNamingPolicy.CamelCase
        };

        string configuredName = options.PropertyNamingPolicy.DefaultOrConvertName("ShippingAddress");
        Console.WriteLine(configuredName); // Output: "shippingAddress"

}
}
