How do I check type of dynamic datatype at runtime?

Both solutions are working for me. In the documentation Smeegs linked to, the is keyword was mentioned. And I came up with a slightly more readable solution:

if(value is Boolean) { } and if(value is List<Person>) { }

A working test:

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication3348
{
    class Program
    {
        class Person
        {
            string Name = "";
        }

        static void Main(string[] args)
        {

            Console.WriteLine("Assigning List to value");
            dynamic value = new List<Person>();

            if (value is List<Person>)
            {
                Console.WriteLine("value is a list");
            }

            value = false;

            Console.WriteLine("Assigning bool to value");
            if (value is Boolean)
            {
                Console.WriteLine("value is bool");
            }

            Console.Read();
        }
    }
}

Just read this on another SO question...hopefully it will do the trick for you:

Type unknown = ((ObjectHandle)tmp).Unwrap().GetType();
