範例

以下範例將 X.509 憑證檔案載入物件 X509Certificate ，將憑證匯出為位元組陣列，然後將該位元組陣列匯入另一個 X509Certificate 物件。

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);
    }
}

Imports System.Security.Cryptography.X509Certificates


Module X509

    Sub Main()

        ' The path to the certificate.
        Dim Certificate As String = "test.pfx"

        ' Load the certificate into an X509Certificate object.
        Dim cert As New X509Certificate(Certificate)


        Dim certData As Byte() = cert.Export(X509ContentType.Cert)

        Dim newCert As New X509Certificate(certData)

        ' Get the value.
        Dim resultsTrue As String = newCert.ToString(True)

        ' Display the value to the console.
        Console.WriteLine(resultsTrue)

        ' Get the value.
        Dim resultsFalse As String = newCert.ToString(False)

        ' Display the value to the console.
        Console.WriteLine(resultsFalse)

    End Sub
End Module

備註

該contentType參數僅接受以下列舉值X509ContentType：Cert、、 SerializedCert Pkcs12和。若傳遞其他值，則會拋出 a CryptographicException 。
