ServicePoint.ReceiveBufferSize Propriedade

Definição

Obtém ou define o tamanho do buffer recetor para o soquete usado por este ServicePoint.

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

Valor de Propriedade

A Int32 que contém o tamanho, em bytes, do buffer de receção. O padrão é 8192.

Exceções

O valor especificado para uma operação de conjunto é maior do que Int32.MaxValue.

Observações

Atenção

WebRequest, HttpWebRequest, ServicePoint, e WebClient são obsoletos, e não deves usá-los para novos desenvolvimentos. Utilize HttpClient em substituição.

Para obter informações adicionais, consulte ReceiveBufferSize.

Note

Desde .NET 9, HttpWebRequest usa SocketsHttpHandler.ConnectCallback para definir Socket.ReceiveBufferSize ao valor desta propriedade.
