SHA1 Hashing diffrenece between .net and Js

I am sha1 hashing in js like that:

Js(crypto-js’)

var requestString = generateRequestString(obj);
var hashSha1 =     CryptoJS.SHA1(test+apiKey+requestString);
var hashInBase64 =     CryptoJS.enc.Base64.stringify(hashSha1); 
return hashInBase64

I am try to sha1 hashing in .net but results are diffrent.

using var sha1 = SHA1.Create();  
byte[] hashBytes =   sha1.ComputeHash(Encoding.UTF8.GetBytes(test+apiKey+requestString);
string hashInBase64 = Convert.ToBase64String(hashBytes);

What can i do to getting same result from .net
