SocketOptionLevel 列舉

定義

命名空間:

System.Net.Sockets

組件:

System.Net.Sockets.dll

組件:

System.dll

組件:

netstandard.dll

定義 SetSocketOption(SocketOptionLevel, SocketOptionName, Int32) 和 GetSocketOption(SocketOptionLevel, SocketOptionName) 方法的通訊端 (Socket) 選項層級。

public enum class SocketOptionLevel

public enum SocketOptionLevel

type SocketOptionLevel = 

Public Enum SocketOptionLevel

繼承

ValueType

Enum

SocketOptionLevel

欄位

IP	0	Socket 選項只套用至 IP 通訊端。
IPv6	41	Socket 選項只適用於 IPv6 通訊端。
Socket	65535	Socket 選項會套用至所有通訊端。
Tcp	6	Socket 選項只套用至 TCP 通訊端。
Udp	17	Socket 選項只套用至 UDP 通訊端。

範例

下列範例會使用此列舉來設定通訊端選項。

// Specifies that send operations will time-out 
// if confirmation is not received within 1000 milliseconds.
s->SetSocketOption( SocketOptionLevel::Socket, SocketOptionName::SendTimeout, 1000 );

// Specifies that the Socket will linger for 10 seconds after Close is called.
LingerOption^ lingerOption = gcnew LingerOption( true,10 );

s->SetSocketOption( SocketOptionLevel::Socket, SocketOptionName::Linger, lingerOption );

// Send operations will time-out if confirmation
// is not received within 1000 milliseconds.
s.SetSocketOption (SocketOptionLevel.Socket, SocketOptionName.SendTimeout, 1000);

// The socket will linger for 10 seconds after Socket.Close is called.
LingerOption lingerOption = new LingerOption (true, 10);

s.SetSocketOption (SocketOptionLevel.Socket, SocketOptionName.Linger, lingerOption);

'Send operations will time-out if confirmation is 
' not received within 1000 milliseconds.
s.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.SendTimeout, 1000)

' The socket will linger for 10 seconds after Socket.Close is called.
Dim lingerOption As New LingerOption(True, 10)
s.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.Linger, lingerOption)

備註

列舉 SocketOptionLevel 會定義可傳遞至 和 Socket.GetSocketOption 方法的 Socket.SetSocketOption 通訊端選項層級。 SocketOptionName 列舉值會依 SocketOptionLevel 分組。

注意 若要在 Windows XP 上使用 IPv6，請安裝適用于 Windows XP 的進階網路套件。
