X509Certificate2.GetNameInfo Method

Note: This method is new in the .NET Framework version 2.0.

Gets the subject and issuer names from a certificate.

Namespace: System.Security.Cryptography.X509Certificates
Assembly: System (in system.dll)

public string GetNameInfo (
	X509NameType nameType,
	bool forIssuer
)
public String GetNameInfo (
	X509NameType nameType, 
	boolean forIssuer
)
public function GetNameInfo (
	nameType : X509NameType, 
	forIssuer : boolean
) : String

Parameters

nameType

The X509NameType value for the subject.

forIssuer

true to include the issuer name; otherwise, false.

Return Value

The name of the certificate.

This method should always be used instead of parsing the certificate, since many of the name values can be located in multiple locations. Using this method ensures that the appropriate name is returned.

The following code example opens the current user certificate store, selects only active certificates, then allows the user to select one or more certificates. The example then writes certificate information to the console.

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("Public Key: {0}{1}",x509.PublicKey.Key.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();
			}
		catch (CryptographicException)
			{
				   Console.WriteLine("Information could not be written out for this certificate.");
			}
