.Net Core Equivalent to CryptoJS.AES.encrypt

Question

I have below JavaScript code that uses CryptoJS.AES.encrypt function from CryptoJS library and I am looking for equivalent .Net Core code, can anyone please guide?

        var myData = '';
        var key1 = '';
        var key2 = '';

        var encryptedData = CryptoJS.AES.encrypt(CryptoJS.enc.Utf8.parse(myData.substr(0, myData.length - 1)), CryptoJS.enc.Utf8.parse(key1),
            {
                keySize: 128 / 8,
                iv: CryptoJS.enc.Utf8.parse(key2),
                mode: CryptoJS.mode.CBC,
                padding: CryptoJS.pad.Pkcs7
            });

Edit

I have found below code for .Net Core:

public string EncryptString(string text, string keyString, string ivString)
        {
            var key = Encoding.UTF8.GetBytes(keyString);

            using (var aesAlg = Aes.Create())
            {
                using (var encryptor = aesAlg.CreateEncryptor(key, aesAlg.IV))
                {
                    using (var msEncrypt = new MemoryStream())
                    {
                        using (var csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write))
                        using (var swEncrypt = new StreamWriter(csEncrypt))
                        {
                            swEncrypt.Write(text);
                        }

                        var iv = aesAlg.IV;

                        var decryptedContent = msEncrypt.ToArray();

                        var result = new byte[iv.Length + decryptedContent.Length];

                        Buffer.BlockCopy(iv, 0, result, 0, iv.Length);
                        Buffer.BlockCopy(decryptedContent, 0, result, iv.Length, decryptedContent.Length);

                        return Convert.ToBase64String(result);
                    }
                }
            }
        }

But I am not sure how to specify these options as specified in JavaScript code:

 {
                    keySize: 128 / 8,
                    iv: CryptoJS.enc.Utf8.parse(key2),
                    mode: CryptoJS.mode.CBC,
                    padding: CryptoJS.pad.Pkcs7
                }

Edit 2

I updated my C# code following suggestions from Topaco and below is my code. But when I test it the output of my C# code and JavaScript code is different can anyone please guide what's missing?

public string RequestHash(string text, string keyString, string ivString)
        {
            var key = Encoding.UTF8.GetBytes(keyString);
            var iv = Encoding.UTF8.GetBytes(ivString);

            using (var aesAlg = Aes.Create())
            {
                using (var encryptor = aesAlg.CreateEncryptor(key, iv))
                {
                    using (var msEncrypt = new MemoryStream())
                    {
                        using (var csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write))
                        using (var swEncrypt = new StreamWriter(csEncrypt))
                        {
                            swEncrypt.Write(text);
                        }

                        var decryptedContent = msEncrypt.ToArray();
                        return Convert.ToBase64String(decryptedContent);
                    }
                }
            }
        } 

Answer 1

Thank you so much Topaco for your help, really appreciate!

Here's my final code:

public string RequestHash(string text, string keyString, string ivString)
{
    var key = Encoding.UTF8.GetBytes(keyString);
    var iv = Encoding.UTF8.GetBytes(ivString);

    using (var aesAlg = Aes.Create())
    {
        using (var encryptor = aesAlg.CreateEncryptor(key, iv))
        {
            using (var msEncrypt = new MemoryStream())
            {
                using (var csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write))
                using (var swEncrypt = new StreamWriter(csEncrypt))
                {
                    swEncrypt.Write(text);
                }

                var decryptedContent = msEncrypt.ToArray();
                return Convert.ToBase64String(decryptedContent);
            }
        }
    }
}
