Ad Alanı:

System.Net.Security

Bütünleştirilmiş Kod:

System.Net.Security.dll

NegotiateStream sınıfının yeni bir örneğini başlatır.

Aşırı Yüklemeler

NegotiateStream(Stream)	Belirtilen Streamkullanarak sınıfının yeni bir örneğini NegotiateStream başlatır.

Örnekler

Aşağıdaki kod örneğinde bu oluşturucunun çağrılması gösterilmektedir.

NegotiateStream(Stream, Boolean)

Kaynak:

NegotiateStream.cs

Belirtilen Stream ve akış kapatma davranışını kullanarak sınıfının yeni bir örneğini NegotiateStream başlatır.

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)

Parametreler

innerStream

Stream

Stream tarafından NegotiateStream veri göndermek ve almak için kullanılan nesne.

leaveInnerStreamOpen

Boolean

true kapatmanın NegotiateStream üzerinde innerStreamhiçbir etkisi olmadığını belirtmek için ; false kapatmanın NegotiateStream da kapatıldığını innerStreambelirtir.

Özel durumlar

ArgumentNullException

innerStream, null değeridir.

-veya-

innerStream Nulleşittir.

Örnekler

Açıklamalar

parametresini belirttiğinizde trueleaveStreamOpen, öğesini kapatmanın innerStreamNegotiateStream akış üzerinde hiçbir etkisi yoktur; artık ihtiyacınız olmadığında açıkça kapatmanız innerStream gerekir.
