Value cannot be null. Parameter name: type at System.Activator.CreateInstance(Type type, Boolean nonPublic)

I have created constructor method with object parameter. But still the same issue

namespace MoveFile
{
    public partial class MoveFile
    {
        public MoveFile(object args)
        {
            DoWork();
        }
        public void DoWork()
        {
            EventLog.CreateEventSource("InfiniteTS", "Thread Working");
        }
    }
}
