Execute OrderBy with parameter

I'm creating a endpoint to retrieve some data from my database, I'm trying to create a custom order by functionallity in my front end so I can call my endpoint with something like this:

https://someapiurl/api/v1/controller/GetItems?ID=1&OrderBy=Name desc

And this is the code that I have in my endpoint:

//This is an example of how I populate my variable which works fine (I have the elements from the database). List is a Iqueryable<ModelName> object.
var list = dbContext.SomeEntity.FindAll...

//Code to get "Name" instead of "Name desc"
var param = orderByQueryString.Split(' ')[0];

if (orderByQueryString.Contains("asc"))
    return list.OrderBy(x => param);
else
    return list.OrderByDescending(x => param);

With both returns I'm getting my list in ascending order. But if I do the following code:

return list.OrderBy(x => x.Name);

Or

return list.OrderByDescending(x => x.Name);

Both works fine so my question is, what can I do to have the orderby element dinamically in that code, because sometimes I'll send Name, sometimes Id or CreatedDate or something like that.

Btw... I tried with list.OrderBy(param); but I got The type arguments for method 'method' cannot be inferred from the usage error message.
