Access Array declared in C# Controller in Razor

I have a 2D Array declared in my MVC Controller, and I need to access this via Razor so I can loop through each value.

I create a session and set it as the array, but I can't figure out how to access the array through razor.

Controller:

string[,] Things = new string[,] {
            { "thing1", "pie" },
            { "thing1", "cake" },
            { "thing1", "potato" }
        };

public void GetThings()
{
    Session["Things"] = Things;
}

public ActionResult Index()
{
    GetThings();
    return View();
}

Razor:

@{
    for (int i = 0; i < Session["Things"].GetLength(0); i++)
    {
        @i
    }
}

I get the error "'object' does not contain a definition for Getlength, the only suggested actions are .Equals, .GetHashCode, .GetType, and .ToString.

The above c# in the razor works if I declare the array within the razor, replacing "Session..." with the array variable name.

I can't read any values from the array session to display on the HTML front end, doing @Session["Things"] displays System.String[,] in browser (but then this is the same as if I tried to call the array declared in razor), @Session["Things"][1,1] gives browser error

Cannot apply indexing with [] to an expression of type 'object'

Cast to array:

((string[,])Session["Things"]).GetLength(0)
