Inicializuje novou instanci NegotiateStream třídy.

Přetížení

NegotiateStream(Stream)

Inicializuje novou instanci NegotiateStream třídy pomocí zadané Stream.
NegotiateStream(Stream, Boolean)

Inicializuje novou instanci NegotiateStream třídy pomocí zadaného Stream chování a chování uzavření datového proudu.

Poznámky

Chcete-li zabránit NegotiateStream zavření datového proudu, který zadáte, použijte NegotiateStream(Stream, Boolean) konstruktor.

NegotiateStream(Stream, Boolean)

Zdroj:
NegotiateStream.cs
Zdroj:
NegotiateStream.cs
Zdroj:
NegotiateStream.cs

Inicializuje novou instanci NegotiateStream třídy pomocí zadaného Stream chování a chování uzavření datového proudu.

public:
 NegotiateStream(System::IO::Stream ^ innerStream, bool leaveInnerStreamOpen);
public NegotiateStream (System.IO.Stream innerStream, bool leaveInnerStreamOpen);
new System.Net.Security.NegotiateStream : System.IO.Stream * bool -> System.Net.Security.NegotiateStream
Public Sub New (innerStream As Stream, leaveInnerStreamOpen As Boolean)

Parametry

innerStream
Stream

Objekt Stream používaný objektem NegotiateStream pro odesílání a příjem dat.

leaveInnerStreamOpen
Boolean

true pro označení, že zavření nemá NegotiateStream žádný vliv na innerStream; false pro označení, že zavření také NegotiateStream zavře innerStream.

Výjimky

ArgumentNullException

innerStream je null.

-nebo-

innerStream se rovná hodnotě Null.

Poznámky

Když pro parametr zadátetrue, nemá zavření datového NegotiateStream proudu žádný vliv. Pokud už ho nepotřebujete, musíte ho innerStream explicitně zavřítinnerStream.leaveStreamOpen
