如何使用X509证书和C#进行非对称加密？

using System;
using System.Security.Cryptography.X509Certificates;
using System.Text;

class Program
{
    static void Main(string[] args)
    {
        // 加载X509证书
        X509Certificate2 certificate = new X509Certificate2("path/to/certificate.pfx", "password");

        // 创建RSA加密服务提供程序
        RSACryptoServiceProvider rsa = (RSACryptoServiceProvider)certificate.PublicKey.Key;

        // 加密数据
        byte[] data = Encoding.UTF8.GetBytes("Hello, world!");
        byte[] encryptedData = rsa.Encrypt(data, true);

        // 解密数据
        byte[] decryptedData = rsa.Decrypt(encryptedData, true);
        string decryptedString = Encoding.UTF8.GetString(decryptedData);

        Console.WriteLine("Encrypted data: " + Convert.ToBase64String(encryptedData));
        Console.WriteLine("Decrypted data: " + decryptedString);
    }
}
