Pass complex object on Post Redirection without TempData in .Net Core.

Currently, I'm working with the following approach and It's working fine but I want to remove the use of TempData. What can I do?

//my class

public myClass{

public int id {get;set;}

public string name {get;set;}

public anotherClass another {get;set;}

}

public anotherClass{

public int id2 {get;set;}

public string name2 {get;set;}

}

//my action method

[HttpPost]

public async Task Search(string searchId)

{

var ob=new myClass();

TempData["myClass"] = JsonConvert.SerializeObject(ob);

return RedirectToAction("DataList");

}

[HttpGet]

public IActionResult DataList()

{

var val = TempData.Peek("myClass");

var res = JsonConvert.DeserializeObject(val.ToString());

return View(res);

}

Query string can be an alternative here. You can pass Json string as querystring value with RedirectToAction method.You can Encrypt the object if required.
return this.RedirectToAction ("myActionName", new { value1 = "queryStringValue1" });
Even though there is a difference between Session and TempData.

TempData also uses session that's why I don't want to use TempData nor Session.

You can use Session also,
