範例

下列範例會 GetCertHashString 使用 方法來取得 X.509 憑證雜湊值、將它轉換成字串，並將其顯示至主控台。

using namespace System;
using namespace System::Security::Cryptography::X509Certificates;
int main()
{
   
   // The path to the certificate.
   String^ Certificate = "Certificate.cer";
   
   // Load the certificate into an X509Certificate object.
   X509Certificate^ cert = X509Certificate::CreateFromCertFile( Certificate );
   
   // Get the value.
   String^ results = cert->GetCertHashString();
   
   // Display the value to the console.
   Console::WriteLine( results );
}

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

public class X509
{

    public static void Main()
    {

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

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

        // Get the value.
        string results = cert.GetCertHashString();

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

Imports System.Security.Cryptography.X509Certificates

Public Class X509
   
   
   Public Shared Sub Main()
      
      ' The path to the certificate.
      Dim Certificate As String = "Certificate.cer"
      
      ' Load the certificate into an X509Certificate object.
      Dim cert As X509Certificate = X509Certificate.CreateFromCertFile(Certificate)
      
      ' Get the value.
      Dim results As String = cert.GetCertHashString()
      
      ' Display the value to the console.
      Console.WriteLine(results)
   End Sub 
End Class
