ServicePoint.ReceiveBufferSize 屬性
重要
部分資訊涉及發行前產品,在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊,不做任何明確或隱含的瑕疵擔保。
取得或設定這個 ServicePoint所使用的套接字接收緩衝區大小。
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
Int32,其中包含接收緩衝區的大小,以位元組為單位。 預設值為8192。
設定作業指定的值大於 Int32.MaxValue。
下列程式代碼範例會設定這個屬性的值。

警告
WebRequest
、HttpWebRequest
、ServicePoint
和 WebClient
已經過時,您不應該將它們用於新的開發。 請改用 HttpClient。
