How to: invoke C# generic method dynamically

Here is the sample code I figure out, using System; namespace X {     class Program     {         static void Main(string[] args)         {             string byString = "Today"; //or tomorow             var GenericType = Type.GetType("X." + byString);             var GenericIns = Activator.CreateInstance(GenericType);             var genericMethod = typeof(Program).GetMethod("GetList")                 .MakeGenericMethod(GenericType);             var output = genericMethod.Invoke(null, new object[] { GenericIns });         }         public static T GetList<T>(T input) where T : new()         {             Console.WriteLine("Invoked " + input);             return input;         }     }     class Today     {     }     class Tomorrow     {     } }
