サンプルコード

using System;
using System.Collections;
using System.Net;
using System.Net.Sockets;
using System.Net.Security;
using System.Security.Authentication;
using System.Text;
using System.Security.Cryptography.X509Certificates;
using System.IO;

namespace app
{
	public class test0 {
		private static void PrintCertificate(X509Certificate certificate) {
			Console.WriteLine("Subject: {0}", certificate.Subject);
			Console.WriteLine("Issuer: {0}", certificate.Issuer);
			Console.WriteLine("Format: {0}", certificate.GetFormat());
			Console.WriteLine("ExpirationDate: {0}", certificate.GetExpirationDateString());
			Console.WriteLine("EffectiveDate: {0}", certificate.GetEffectiveDateString());
			Console.WriteLine("KeyAlgorithm: {0}", certificate.GetKeyAlgorithm());
			Console.WriteLine("PublicKey: {0}", certificate.GetPublicKeyString());
			Console.WriteLine("SerialNumber: {0}", certificate.GetSerialNumberString());
		}
		public static int Main(string[] args) {
			string certPath = "certificate.crt";
			X509Certificate cert = X509Certificate.CreateFromCertFile(certPath);
			PrintCertificate(cert);
			return 0;
		}
	}
}
