示例

以下示例将 X.509 证书文件加载到对象 X509Certificate 中，将证书导出为字节数组，然后将字节数组导入另一个 X509Certificate 对象。

using namespace System;
using namespace System::Security::Cryptography::X509Certificates;
int main()
{
   
   // The path to the certificate.
   String^ Certificate = L"test.pfx";
   
   // Load the certificate into an X509Certificate object.
   X509Certificate^ cert = gcnew X509Certificate( Certificate );
   array<Byte>^certData = cert->Export( X509ContentType::Cert );
   X509Certificate^ newCert = gcnew 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 );
}

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

注解

参数 contentType 仅接受枚举的 X509ContentType 以下值： Cert、 SerializedCert和 Pkcs12。传递任何其他值都会导致 CryptographicException 引发。
