从嵌套的子属性中获取父匿名类型属性的值。 如何？

Question

This task is trivial in Javascript but in C#, I can't find a way to do it.

I have an anonymous type containing nested anonymous types. These child types contain the property rootLength that should ultimately be set to the value of the parent like a Global if you will.

How do I set the value of children based on the value of parent?

var opensslSettings = new 
{
    rootLength = 2048,
    pkcs3 = new 
    {
        rootLength = 2048,
        outDir = AppDomain.CurrentDomain.BaseDirectory,
        outDhp = "www_example_com_2048bit.pkcs3"
    },
    pkcs10 = new 
    {
        rootLength = 2048,
        outDir = AppDomain.CurrentDomain.BaseDirectory,
        outKeyFile = "www_example_com_2048bit.pkcs8",
        outCsrFile = "www_example_com_2048bit.pkcs10"
    },
};

Console.WriteLine(opensslSettings.ToString());

Below, the working example for completion.

using System.Diagnostics;
using System.Text.Json.Nodes;

namespace asynchronousCode
{
    class Program
    {
        public async static Task Main(string[] args)
        {
            var rootLength = 2048;

            var opensslSettingsJson = new JsonObject
            {
                ["rootLength"] = rootLength,
                ["pkcs3"] = new JsonObject 
                {
                    ["rootLength"] = rootLength,
                    ["outDir"] = AppDomain.CurrentDomain.BaseDirectory,
                    ["outDhp"] = $"www_example_com_{rootLength}bit.pkcs3"
                },
                ["pkcs10"] = new JsonObject
                {
                    ["rootLength"] = rootLength,
                    ["outDir"] = AppDomain.CurrentDomain.BaseDirectory,
                    ["outKeyFile"] = $"www_example_com_{rootLength}bit.pkcs8",
                    ["outCsrFile"] = $"www_example_com_{rootLength}bit.pkcs10"
                },
            };

            Console.WriteLine(opensslSettingsJson.ToJsonString() + Environment.NewLine);

            var opensslSettingsObject = new 
            {
                rootLength = rootLength,
                pkcs3 = new 
                {
                    rootLength = rootLength,
                    outDir = AppDomain.CurrentDomain.BaseDirectory,
                    outDhp = $"www_example_com_{rootLength}bit.pkcs3"
                },
                pkcs10 = new 
                {
                    rootLength = rootLength,
                    outDir = AppDomain.CurrentDomain.BaseDirectory,
                    outKeyFile = $"www_example_com_{rootLength}bit.pkcs8",
                    outCsrFile = $"www_example_com_{rootLength}bit.pkcs10"
                },
            };
        }
    }
}
