定義

名前空間:
System.Net
アセンブリ:
System.dll
アセンブリ:
netstandard.dll

この ServicePointで使用されるソケットの受信バッファーのサイズを取得または設定します。

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

プロパティ値

Int32

受信バッファーのサイズ (バイト単位) を含む Int32 。 既定値は 8192 です。

例外

ArgumentOutOfRangeException

設定操作に指定された値が Int32.MaxValue より大きい。

注釈

Caution

WebRequest、 HttpWebRequest、 ServicePoint、 WebClient は廃止されており、新しい開発には使用しないでください。 HttpClient を代わりに使用します。

追加情報については、ReceiveBufferSizeを参照してください。

Note

.NET 9 以降、HttpWebRequest では SocketsHttpHandler.ConnectCallback を使用して、Socket.ReceiveBufferSize をこのプロパティの値に設定します。
