C# Object 未设置键值类型

Question

My goal: I want to create a system that can have key value pairs but that I don't need to beforehand set either the key or the value's data type

What I am trying to emulate to an extent is pythons dictionaries

example of what I want

{
  "hotbar"=
  {
             {"slot_1"={"item"="dirt","amount"=3},
             {"slot_3"={"item"="shovel","amount"=1,"usesLeft"=135}
  }
  "walkspeed"=10
  "jumpPower"=15
  "position"={"x"=10,"y"=3,"z"=31.3}

similar to Minecraft's nbt system is my goal

the syntax does not need to be perfectly the same just as long as I can store it with a key and value without it mattering what type of key and value it is

And I want to be able to read and write individual values from this (including nested values) and also to loop through all of the key value pairs as well

please recomend me better tags

Key value things is Dictionary https://www.tutorialsteacher.com/csharp/csharp-dictionary but in OOP you can just use List of objects
eg //Design Objects (classes)

public class Hotbar { //Hotbar class
   public string key_name {get;set;}
   public stirng item {get;set;}
   public int amount{get;set;}   
   public int usesLeft{get;set;}
}

public class YourMainClass{
  public List<Hotbar> hotbar_List {get;set;}
  public int walkspeed {get;set;}
  public int jumpPower {get;set;}
  public PositionObj position {get;set;} // go create object of position
  public YourMainClass(){
   // constructor  Init List 
   hotbar_List   =new List<hotbar>();
  }

}

example how to use

YourMainClass targetObj =new YourMainClass();
// create new Hotbar
  Hotbar  hotbar1  =new Hotbar();
  hotbar1.key_name  = "slot_1";
  hotbar1.item  ="dirt";
  hotbar1.amount= 3;
// add  hotbar #1
 targetObj.hotbar_List.Add(hotbar1);

// get hot bar slot_1
 Hotbar thatHot = targetObj.hotbar_List.Where(o=>o.key_name  =="slot_1").FirstOrDefault();

// for looping - will loop if there are obj in List
 foreach( Hotbar  oneHotBar from  targetObj.hotbar_List  ){
  // do something with hotbar   Obj call oneHotBar 
   string name_of_item = oneHotBar.key_name  ; 
  // try minus amount 
   if( oneHotBar .key_name  =="slot_1" )
   {
      oneHotBar. amount =  oneHotBar. amount-1;
   }
 }

ps sorry I'm not fluent with Dictionary please wait for others.
