X509Certificate Constructor (Byte[])

X509Certificate Constructor (Byte[])

Initializes a new instance of the X509Certificate class defined from a sequence of bytes representing an X.509v3 certificate.

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

public X509Certificate (
	byte[] data
)
public X509Certificate (
	byte[] data
)
public function X509Certificate (
	data : byte[]
)

Parameters

data

A byte array containing data from an X.509 certificate.

Exception typeCondition

ArgumentException

The rawData parameter is a null reference (Nothing in Visual Basic).

-or-

The length of the rawData parameter is 0.

ASN.1 DER is the only certificate format supported by this class.

The following example loads an X.509 certificate file into an X509Certificate object, exports the certificate as a byte array, and then imports the byte array into another X509Certificate object.

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


public class X509
{

    public static void Main()
    {

        // The path to the certificate.
        string Certificate = "test.pfx";

        // Load the certificate into an X509Certificate object.
        X509Certificate cert = new X509Certificate(Certificate);


        byte[] certData = cert.Export(X509ContentType.Cert);

        X509Certificate newCert = new X509Certificate(certData);

        // Get the value.
        string resultsTrue = newCert.ToString(true);

        // Display the value to the console.
        Console.WriteLine(resultsTrue);

        // Get the value.
        string resultsFalse = newCert.ToString(false);

        // Display the value to the console.
        Console.WriteLine(resultsFalse);

    }
