Convert Dictionary<String,Int> to Dictionary<String,SomeEnum> using LINQ?

It works straight forward with a simple cast.

Dictionary<String, Int32> input = new Dictionary<String, Int32>();

// Transform input Dictionary to output Dictionary

Dictionary<String, SomeEnum> output =
   input.ToDictionary(item => item.Key, item => (SomeEnum)item.Value);

I used this test and it does not fail.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Diagnostics;

namespace DictionaryEnumConverter
{
    enum SomeEnum { x, y, z = 4 };

    class Program
    {
        static void Main(string[] args)
        {           
            Dictionary<String, Int32> input =
               new Dictionary<String, Int32>();

            input.Add("a", 0);
            input.Add("b", 1);
            input.Add("c", 4);

            Dictionary<String, SomeEnum> output = input.ToDictionary(
               pair => pair.Key, pair => (SomeEnum)pair.Value);

            Debug.Assert(output["a"] == SomeEnum.x);
            Debug.Assert(output["b"] == SomeEnum.y);
            Debug.Assert(output["c"] == SomeEnum.z);
        }
    }
}

var result = dict.ToDictionary(kvp => kvp.Key,
               kvp => (SomeEnum)Enum.ToObject(typeof(SomeEnum), kvp.Value));
