ServicePoint.Certificate プロパティ

定義

名前空間:

System.Net

アセンブリ:

System.Net.ServicePoint.dll

アセンブリ:

ServicePoint オブジェクト用に受信した証明書を取得します。

public:
 property System::Security::Cryptography::X509Certificates::X509Certificate ^ Certificate { System::Security::Cryptography::X509Certificates::X509Certificate ^ get(); };

public System.Security.Cryptography.X509Certificates.X509Certificate? Certificate { get; }

public System.Security.Cryptography.X509Certificates.X509Certificate Certificate { get; }

member this.Certificate : System.Security.Cryptography.X509Certificates.X509Certificate

Public ReadOnly Property Certificate As X509Certificate

プロパティ値

X509Certificate

この ServicePoint オブジェクト用に受信したセキュリティ証明書を格納している X509Certificate クラスのインスタンス。

例

次のコード例では、このプロパティの値を表示します。

if ( sp->Certificate == nullptr )
   Console::WriteLine( "Certificate = (null)" );
else
   Console::WriteLine( "Certificate = {0}", sp->Certificate );

if ( sp->ClientCertificate == nullptr )
   Console::WriteLine( "Client Certificate = (null)" );
else
   Console::WriteLine( "Client Certificate = {0}", sp->ClientCertificate );

Console::WriteLine( "ProtocolVersion = {0}", sp->ProtocolVersion->ToString() );
Console::WriteLine( "SupportsPipelining = {0}", sp->SupportsPipelining );

if (sp.Certificate == null)
    Console.WriteLine("Certificate = (null)");
else
    Console.WriteLine("Certificate = " + sp.Certificate.ToString());

if (sp.ClientCertificate == null)
    Console.WriteLine("ClientCertificate = (null)");
else
    Console. WriteLine("ClientCertificate = " + sp.ClientCertificate.ToString());

Console.WriteLine("ProtocolVersion = " + sp.ProtocolVersion.ToString());
Console.WriteLine("SupportsPipelining = " + sp.SupportsPipelining);

If sp.Certificate Is Nothing Then
    Console.WriteLine("Certificate = (null)")
Else
    Console.WriteLine(("Certificate = " + sp.Certificate.ToString()))
End If

If sp.ClientCertificate Is Nothing Then
    Console.WriteLine("ClientCertificate = (null)")
Else
    Console.WriteLine(("ClientCertificate = " + sp.ClientCertificate.ToString()))
End If

Console.WriteLine("ProtocolVersion = " + sp.ProtocolVersion.ToString())
Console.WriteLine(("SupportsPipelining = " + sp.SupportsPipelining.ToString()))

注釈

オブジェクトは ServicePoint インターネット リソースに複数の接続を行うことができますが、保持できる証明書は 1 つだけです。

注意

.NET Core および .NET 5 以降では、このプロパティは Certificate 常に null を返します。 サーバー証明書にアクセスするには、次を使用 ServerCertificateCustomValidationCallbackします。
