.Net Core Equivalent to CryptoJS.AES.encrypt - asp.net-core

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
}

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);
}
}
}
}

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);
}
}
}
}
