ServicePoint.ReceiveBufferSize Eigenschap

Definitie

Hiermee haalt u de grootte van de ontvangende buffer op of stelt u deze in voor de socket die door deze ServicePointbuffer wordt gebruikt.

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

Waarde van eigenschap

Een Int32 die de grootte in bytes van de ontvangstbuffer bevat. De standaardwaarde is 8192.

Uitzonderingen

De waarde die is opgegeven voor een setbewerking is groter dan Int32.MaxValue.

Voorbeelden

In het volgende codevoorbeeld wordt de waarde van deze eigenschap ingesteld.

Opmerkingen

Caution

WebRequest, HttpWebRequest, ServicePointen WebClient zijn verouderd en u moet ze niet gebruiken voor nieuwe ontwikkeling. Gebruik in plaats daarvan HttpClient.

Zie ReceiveBufferSizevoor meer informatie.

Note

Sinds .NET 9 gebruikt HttpWebRequestSocketsHttpHandler.ConnectCallback om Socket.ReceiveBufferSize in te stellen op de waarde van deze eigenschap.
