SocketOptionLevel 枚举

定义

命名空间:

System.Net.Sockets

程序集:

System.Net.Sockets.dll

程序集:

System.dll

程序集:

netstandard.dll

为 SetSocketOption(SocketOptionLevel, SocketOptionName, Int32) 和 GetSocketOption(SocketOptionLevel, SocketOptionName) 方法定义套接字选项级别。

public enum class SocketOptionLevel

public enum SocketOptionLevel

type SocketOptionLevel = 

Public Enum SocketOptionLevel

继承

Object

ValueType

Enum

SocketOptionLevel

字段

IP	0	Socket 选项仅适用于 IP 套接字。
IPv6	41	Socket 选项仅适用于 IPv6 套接字。
Socket	65535	Socket 选项适用于所有套接字。
Tcp	6	Socket 选项仅适用于 TCP 套接字。
Udp	17	Socket 选项仅适用于 UDP 套接字。

示例

以下示例使用此枚举来设置套接字选项。

// 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)

注解

SocketOptionLevel枚举定义可传递给Socket.SetSocketOption和Socket.GetSocketOption方法的套接字选项级别。 SocketOptionName 枚举值按 SocketOptionLevel.

注意 若要在 Windows XP 上使用 IPv6，请安装适用于 Windows XP 的高级网络包。
