如何为JObject创建唯一的哈希码？

using System.Security.Cryptography;
using Newtonsoft.Json.Linq;

public static string GetUniqueHashCode(JObject jObject)
{
    string jsonString = jObject.ToString();
    
    using (SHA256 sha256 = SHA256.Create())
    {
        byte[] hashBytes = sha256.ComputeHash(System.Text.Encoding.UTF8.GetBytes(jsonString));
        string hashCode = BitConverter.ToString(hashBytes).Replace("-", "").ToLower();
        
        return hashCode;
    }
}
