如何在.NET Framework 2.0中模拟"Func <(Of <(TResult>)>)委托"？

using System;

public class FuncSimulator
{
    public delegate TResult Func<TResult>();

    public static void Main()
    {
        Func<int> func = new Func<int>(GetInt);
        int result = func();
        Console.WriteLine("Result: " + result);
    }

    public static int GetInt()
    {
        return 42;
    }
}
