剃刀上的ViewBag转换成本-C＃MVC

Question

Has someone tried to measure the conversion times of using ViewBag object directly on a comparison to the original object class? Here is an example of what I am talking about. Say I have a class named Client:

public class Client{
    public int Id { get; set; }
    public string Name { get; set; }
}

On a razor file I could do one of the following:

var client = (Client)ViewBag.Client;
var name = client.Name;

Or

var name = (Client)ViewBag.Client.Name;

I was wondering about the cost of the operation directly on the ViewBag object (without the conversion) comparing to the object on its original class. Is the performance, when having multiples calls on ViewBag, an issue?

Answer 1

Well your first example will create 2 variables in your memory. The second example will create 1 variable in your memory.

For the rest I think there is no real performance difference between the two.
