SslStream.LocalCertificate プロパティ

定義

名前空間:

System.Net.Security

アセンブリ:

System.Net.Security.dll

ソース:

SslStream.cs

ローカル エンドポイントの認証に使用する証明書を取得します。

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

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

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

Public Overridable ReadOnly Property LocalCertificate As X509Certificate

プロパティ値

X509Certificate

認証用に提供された証明書を表す X509Certificate オブジェクト。証明書が提供されなかった場合は null。

例外

InvalidOperationException

認証に失敗したか、認証が行われていません。

例

次のコード例は、このプロパティによって返される証明書を表示する方法を示しています。
