You can simulate the vfp do case with a delegate
Disadvantage: all conditions are evaluated
Think I prefer the if - else if - else if

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

namespace GregoryAdam.Test
{
	public class CaseTest
	{
		public static void Main()
		{
			int result = 0;
			int a = 23, b = 27;

			Case.Execute
				(
				new CaseOne( a==1, () => { result = 1;}),
				new CaseOne( b==2, () => { result = 2;}), 
				// otherwise
				new CaseOne( true, () => { result = 99;}) 
				);

			Console.WriteLine("result = {0}", result);
			Console.ReadLine();
		}
	}

	public static class Case
	{
		public static void Execute(params CaseOne[] cases)
		{
			for( int i = -1; ++i < cases.Length; )
				if (cases[i].Condition)
				{
					cases[i].Act();
					break;
				}
		}
	}
	public class CaseOne
	{
		public bool Condition;
		public Action Act;

		public CaseOne(bool condition, Action act)
		{
			Condition = condition;
			Act = act;
		}
	}
