TripleDES .Net to TripleDES (crypto-js) Javascript - cryptojs

Question

I've spent some time looking at all solutions but something still seems off.. The encrypted string I see in .Net does not match the output I see in Cryto-JS. What could be wrong?
public static void Encrypt()
{
string toEncrypt = "123456";
string key = "hello";
TripleDESCryptoServiceProvider tdes = new TripleDESCryptoServiceProvider();
MD5CryptoServiceProvider hashmd5 = new MD5CryptoServiceProvider();
byte[] keyArray = hashmd5.ComputeHash(UnicodeEncoding.Unicode.GetBytes(key));
tdes.Key = keyArray;
tdes.Mode = CipherMode.ECB;
ICryptoTransform cTransform = tdes.CreateEncryptor();
byte[] toEncryptArray = UnicodeEncoding.Unicode.GetBytes(toEncrypt);
byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length);
string finalString = Convert.ToBase64String(resultArray);
Console.WriteLine("Output encrypted .Net: " + finalString);
}
and the equivalent Javascript using crypto-js is
Encrypt = () => {
var CryptoJS = require('crypto-js');
var text = '123456'
var key = "hello";
key = CryptoJS.enc.Utf16LE.parse(key);
key = CryptoJS.MD5(key)
var options = {
mode: CryptoJS.mode.ECB,
};
var textWordArray = CryptoJS.enc.Utf16LE.parse(text);
var encrypted = CryptoJS.TripleDES.encrypt(textWordArray, key, options);
var base64String = encrypted.toString();
console.log('Output JS Encrypted: ' + base64String);
}
I get yGOnLhoVpIHQOCbAn51FTA== in .Net and d5Lg8k8cz68T6akDI0KQrA== in crypto-js.

I have fixed this issue. A console log inside tripledes.js (CryptoJS package) revealed that I was missing 64 more bits in the key after MD5 Hash.
this._des1 = DES.createEncryptor(WordArray.create(keyWords.slice(0, 2)));
this._des2 = DES.createEncryptor(WordArray.create(keyWords.slice(2, 4)));
this._des3 = DES.createEncryptor(WordArray.create(keyWords.slice(4, 6)));
key.words length was 4 instead of 6. So, des3 had an empty wordarray. Solution was to push value of index 0 and 1 into the key word array. With length now being 6, des3 gets the value of des1. i.e keyWords.slice(0, 2) = keyWords.slice(4, 6).
Encrypt = () => {
var CryptoJS = require('crypto-js');
var text = '123456'
var key = "hello";
key = CryptoJS.enc.Utf16LE.parse(key);
key = CryptoJS.MD5(key)
key.words.push(key.words[0], key.words[1]) // FIX FIX FIX
var options = {
mode: CryptoJS.mode.ECB,
};
var textWordArray = CryptoJS.enc.Utf16LE.parse(text);
var encrypted = CryptoJS.TripleDES.encrypt(textWordArray, key, options);
var base64String = encrypted.toString();
console.log('Output JS Encrypted: ' + base64String);
}
