using System;
using System.Security.Cryptography;
using System.Security.Permissions;
using System.IO;
using System.Security.Cryptography.X509Certificates;

class CertSelect
{
	static void Main()
	{
		try
		{
			X509Store store = new X509Store("MY",StoreLocation.CurrentUser);
			store.Open(OpenFlags.ReadOnly | OpenFlags.OpenExistingOnly);
			X509Certificate2Collection collection = (X509Certificate2Collection)store.Certificates;
			X509Certificate2Collection fcollection = (X509Certificate2Collection)collection.Find(X509FindType.FindByTimeValid,DateTime.Now,false);
			X509Certificate2Collection scollection = X509Certificate2UI.SelectFromCollection(fcollection, "Test Certificate Select","Select a certificate from the following list to get information on that certificate",X509SelectionFlag.MultiSelection);
			Console.WriteLine("Number of certificates: {0}{1}",scollection.Count,Environment.NewLine);
				foreach (X509Certificate2 x509 in scollection)
				{
					byte[] rawdata = x509.RawData;
					Console.WriteLine("Content Type: {0}{1}",X509Certificate2.GetCertContentType(rawdata),Environment.NewLine);
					Console.WriteLine("Friendly Name: {0}{1}",x509.FriendlyName,Environment.NewLine);
					Console.WriteLine("Certificate Verified?: {0}{1}",x509.Verify(),Environment.NewLine);
					Console.WriteLine("Simple Name: {0}{1}",x509.GetNameInfo(X509NameType.SimpleName,true),Environment.NewLine);
					Console.WriteLine("Signature Algorithm: {0}{1}",x509.SignatureAlgorithm.FriendlyName,Environment.NewLine);
					Console.WriteLine("Private Key: {0}{1}",x509.PrivateKey.ToXmlString(false),Environment.NewLine);

					Console.WriteLine("Certificate Archived?: {0}{1}",x509.Archived,Environment.NewLine);
					Console.WriteLine("Length of Raw Data: {0}{1}",x509.RawData.Length,Environment.NewLine);
					X509Certificate2UI.DisplayCertificate(x509);
					x509.Reset();
				}
			store.Close();

			{
				   Console.WriteLine("Information could not be written out for this certificate.");
