SslStream.RemoteCertificate 屬性

定義

取得用於驗證遠端端點的憑證。

public:
 virtual property System::Security::Cryptography::X509Certificates::X509Certificate ^ RemoteCertificate { System::Security::Cryptography::X509Certificates::X509Certificate ^ get(); };
public virtual System.Security.Cryptography.X509Certificates.X509Certificate? RemoteCertificate { get; }
public virtual System.Security.Cryptography.X509Certificates.X509Certificate RemoteCertificate { get; }
member this.RemoteCertificate : System.Security.Cryptography.X509Certificates.X509Certificate
Public Overridable ReadOnly Property RemoteCertificate As X509Certificate

屬性值

X509Certificate 物件,表示提供用於驗證的憑證或 null (如果沒有提供憑證的話)。

例外狀況

驗證失敗或尚未執行驗證。

範例

下列程式代碼範例示範如何顯示此屬性傳回的憑證。

   static void DisplayCertificateInformation( SslStream^ stream )
   {
      Console::WriteLine( L"Certificate revocation list checked: {0}", stream->CheckCertRevocationStatus );
      X509Certificate^ localCertificate = stream->LocalCertificate;
      if ( stream->LocalCertificate != nullptr )
      {
         Console::WriteLine( L"Local cert was issued to {0} and is valid from {1} until {2}.", 
             localCertificate->Subject, 
             localCertificate->GetEffectiveDateString(), 
             localCertificate->GetExpirationDateString() );
      }
      else
      {
         Console::WriteLine( L"Local certificate is null." );
      }

      X509Certificate^ remoteCertificate = stream->RemoteCertificate;
      if ( stream->RemoteCertificate != nullptr )
      {
         Console::WriteLine( L"Remote cert was issued to {0} and is valid from {1} until {2}.", 
            remoteCertificate->Subject, 
            remoteCertificate->GetEffectiveDateString(), 
            remoteCertificate->GetExpirationDateString() );
      }
      else
      {
         Console::WriteLine( L"Remote certificate is null." );
      }
   }


private:
static void DisplayCertificateInformation(SslStream stream)
{
    Console.WriteLine("Certificate revocation list checked: {0}", stream.CheckCertRevocationStatus);

    X509Certificate localCertificate = stream.LocalCertificate;
    if (stream.LocalCertificate != null)
    {
        Console.WriteLine("Local cert was issued to {0} and is valid from {1} until {2}.",
            localCertificate.Subject,
            localCertificate.GetEffectiveDateString(),
            localCertificate.GetExpirationDateString());
     } else
    {
        Console.WriteLine("Local certificate is null.");
    }
    // Display the properties of the client's certificate.
    X509Certificate remoteCertificate = stream.RemoteCertificate;
    if (stream.RemoteCertificate != null)
    {
    Console.WriteLine("Remote cert was issued to {0} and is valid from {1} until {2}.",
        remoteCertificate.Subject,
        remoteCertificate.GetEffectiveDateString(),
        remoteCertificate.GetExpirationDateString());
    } else
    {
        Console.WriteLine("Remote certificate is null.");
    }
}
Private Shared Sub DisplayCertificateInformation(stream As SslStream)
    Console.WriteLine("Certificate revocation list checked: {0}", stream.CheckCertRevocationStatus)
    Dim localCertificate As X509Certificate = stream.LocalCertificate

    If stream.LocalCertificate IsNot Nothing Then
        Console.WriteLine("Local cert was issued to {0} and is valid from {1} until {2}.", localCertificate.Subject, localCertificate.GetEffectiveDateString(), localCertificate.GetExpirationDateString())
    Else
        Console.WriteLine("Local certificate is null.")
    End If

    ' Display the properties of the client's certificate.
    Dim remoteCertificate As X509Certificate = stream.RemoteCertificate

    If stream.RemoteCertificate IsNot Nothing Then
        Console.WriteLine("Remote cert was issued to {0} and is valid from {1} until {2}.", remoteCertificate.Subject, remoteCertificate.GetEffectiveDateString(), remoteCertificate.GetExpirationDateString())
    Else
        Console.WriteLine("Remote certificate is null.")
    End If
End Sub

備註

如果存取 屬性,則當 SslStream 實例處置時,將不會處置遠程憑證。 屬性的呼叫端負責處置傳 X509Certificate 回的物件。
