I am doing input parameter checking for a string type, and string value except empty is valid. My function is provided to outer client to call. Sometimes I find to check null is not enough, I also need to check String.Empty.

How can I instantiate a list for the type found above? something like (doesn't work):

public class CreatableTest<T> where T : new()
{
  public static T CreateTestObject()
  {
    return new T();
  }
}

That wont work The type is not known at compile time.

using System;
using System.Collections.Generic;
using System.Text;

namespace MyClass
{
    public class Class1
    {
        public static T Create<T>() where T : new()
        {
            return new T();
        }
    }

    public class MyTest
    {
        public MyTest()
        {
        }
    }
}

using System;
using System.Collections.Generic;
using System.Text;

namespace TestHandler
{
    class Program
    {
        static void Main(string[] args)
        {
            MyClass.MyTest test = MyClass.Class1.Create<MyClass.MyTest>();
            if (test != null)
                Console.WriteLine("Here I am");
            Console.ReadLine();
        }
    }
}
