Socket.ReceiveBufferSize 屬性

定義

取得或設定值,指定 Socket 之接收緩衝區的大小。

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

屬性值

Int32,包含接收緩衝區的大小 (以位元組為單位)。 預設值取決於操作系統。

例外狀況

嘗試存取通訊端時發生錯誤。

為設定作業指定的值小於 0。

範例

下列程式代碼範例示範 屬性的使用 ReceiveBufferSize

static void ConfigureTcpSocket(Socket^ tcpSocket)

    // Socket.Close is called.

備註

較大的緩衝區大小可能會減少沒有數據部分的 TCP 封包 (空通知數目) ,但也可能延遲辨識連線困難。 如果您要傳輸大型檔案,或是使用高頻寬、高延遲連線 (,例如衛星寬頻提供者.) ,請考慮增加緩衝區大小
