Dynamic Call to Database

I'm still digging in and learning .NET, and was wondering if someone can point me in the right direction on something?

Right now, in my Controller, I've got a number of hard-coded calls to some tables within my app's database. Something sort of like this:

if (suppliedTableName == "TableStuff")
{
   var model = await _appDbContext.TableStuff.ToListAsync();
   return View(view, model);
}
if (suppliedTableName== "MyRandomStuff")
{
   var model = await _appDbContext.MyRandomStuff.ToListAsync();
   return View(view, model);
}
if (suppliedTableName== "MySettings")
{
   var model = await _appDbContext.MySettings.ToListAsync();
   return View(view, model);
}

I'm wondering if there's a way to make it more dynamic? Something more like this:

var model = await _appDbContext.VariableSuppliedToControllerWhenCalled.ToListAsync();
return View(view, model);

Can someone give me a nudge in the right direction?

Thanks! And I have to take a quick minute and let all of you know that I appreciate everyone that has helped me in the past - not sure where I'd be without all of you!
