Problem z dictionary i iteracją - C#

Witajcie!
Dlaczego poniższa funkcja niezależnie od podanej wartości zwraca pusty string?
Proszę o podanie wyjaśnień, nie gotowego kodu

namespace Morse_Decoder
{
	public static class MorseMethods
	{
		public static Dictionary<string, char> morseCodeLookup = new Dictionary<string, char>()
		{
			[".- "] = 'a',
			["-... "] = 'b',
			["-.-. "] = 'c',
			["-.. "] = 'd',

			["..-. "] = 'f',
			["--. "] = 'g',

			["...-- "] = '3',
			["....- "] = '4',
			["..... "] = '5',
			["-.... "] = '6',
			["--... "] = '7',
			["---.. "] = '8',
			["----. "] = '9',
			["----- "] = '0',
		};
		public static string DecodeText(string TextToDecode)
		{
			string Result = "";
			string Temp = "";
			string[] MorseTextSplit = TextToDecode.Split(' ');
			for (int i = 0; i == MorseTextSplit.Length; i++)
			{
				Temp += MorseMethods.morseCodeLookup[MorseTextSplit[i]];
				Result += Temp;
			}
			return Result;
		}
	}
}

for (int i = 0; i == MorseTextSplit.Length; i++)
I jest zerem, więc warunek nie zostaje nigdy spełniony, chyba że podasz pustego stringa.

OMG, ale jesztem głupi. Wybaczcie.

Naprawiłem, powiedzcie mi, czy ten kod mogę napisać jakoś łądniej, lepiej, zgrabniej?
