ServicePoint.ReceiveBufferSize Eigenschaft
Definition
Wichtig
Einige Informationen beziehen sich auf Vorabversionen, die vor dem Release ggf. grundlegend überarbeitet werden. Microsoft übernimmt hinsichtlich der hier bereitgestellten Informationen keine Gewährleistungen, seien sie ausdrücklich oder konkludent.
Dient zum Abrufen oder Festlegen der Größe des empfangenden Puffers für den socket, der von diesem ServicePointverwendet wird.
public:
property int ReceiveBufferSize { int get(); void set(int value); };
public int ReceiveBufferSize { get; set; }
member this.ReceiveBufferSize : int with get, set
Public Property ReceiveBufferSize As Integer
Eigenschaftswert
Eine Int32, die die Größe des Empfangspuffers in Byte enthält. Der Standardwert ist 8192.
Ausnahmen
Der für einen Satzvorgang angegebene Wert ist größer als Int32.MaxValue.

Vorsicht
WebRequest
, HttpWebRequest
, ServicePoint
und WebClient
sind veraltet, und Sie sollten sie nicht für die neue Entwicklung verwenden. Verwenden Sie stattdessen HttpClient.
