在c#中为X509Certificate2添加Object标签

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

public class Program
{
    public static void Main()
    {
        // 加载证书文件
        X509Certificate2 certificate = new X509Certificate2("certificate.pfx", "password");

        // 创建一个Object标签的OID（Object Identifier）
        string oid = "1.2.3.4.5";

        // 创建一个Object标签的值
        byte[] value = new byte[] { 0x01, 0x02, 0x03, 0x04, 0x05 };

        // 创建一个X509Extension对象，指定OID和值
        X509Extension extension = new X509Extension(oid, value, false);

        // 将X509Extension对象添加到X509Certificate2对象的Extensions属性中
        certificate.Extensions.Add(extension);

        // 打印证书的所有扩展信息，包括添加的Object标签
        foreach (X509Extension ext in certificate.Extensions)
        {
            Console.WriteLine("Extension OID: " + ext.Oid.Value);
            Console.WriteLine("Extension Value: " + BitConverter.ToString(ext.RawData));
        }
    }
}
