 property System::Net::Sockets::Socket ^ Socket { System::Net::Sockets::Socket ^ get(); };

protected:
 property System::Net::Sockets::Socket ^ Socket { System::Net::Sockets::Socket ^ get(); };

public System.Net.Sockets.Socket Socket { get; }

protected System.Net.Sockets.Socket Socket { get; }

member this.Socket : System.Net.Sockets.Socket

Public ReadOnly Property Socket As Socket

Protected ReadOnly Property Socket As Socket

属性值

Socket

表示基础网络连接的 Socket。

示例

下面的代码示例检索基础 Socket 以验证活动连接。

#using <System.dll>

using namespace System;
using namespace System::Net;
using namespace System::Net::Sockets;

ref class MyNetworkStream_Sub_Class: public NetworkStream
{
public:
   MyNetworkStream_Sub_Class( System::Net::Sockets::Socket^ socket, bool ownsSocket )
      : NetworkStream( socket, ownsSocket )
   {
   }

   property bool IsConnected 
   {
      // You can use the Socket method to examine the underlying Socket.
      bool get()
      {
         return this->Socket->Connected;
      }
   }

   property bool CanCommunicate 
   {
      bool get()
      {
         if ( !this->Readable | !this->Writeable )
         {
            return false;
         }
         else
         {
            return true;
         }
      }
   }

using System;
using System.Net;
using System.Net.Sockets;

public class MyNetworkStream_Sub_Class : NetworkStream
{

    public MyNetworkStream_Sub_Class(Socket socket, bool ownsSocket) :
        base(socket, ownsSocket)
    {
    }
    // You can use the Socket method to examine the underlying Socket.
    public bool IsConnected
    {
        get
        {
            return this.Socket.Connected;
        }
    }

    public bool CanCommunicate
    {
        get
        {
            if (!this.Readable | !this.Writeable)
            {
                return false;
            }
            else
            {
                return true;
            }
        }
    }

Public Class MyNetworkStream_Sub_Class
   Inherits NetworkStream
   
   
   Public Sub New(socket As Socket, ownsSocket As Boolean)
      MyBase.New(socket, ownsSocket)
   End Sub
   
   ' Suppose you wanted a property for determining if Socket is connected. You can use
   ' the protected method 'Socket' to return underlying Socket.
   
   Public ReadOnly Property IsConnected() As Boolean
      Get
         Return Me.Socket.Connected
      End Get
   End Property
   
   ' You could also use public NetworkStream methods 'CanRead' and 'CanWrite'.
   
   Public ReadOnly Property CanCommunicate() As Boolean
      Get
         If Not Me.Readable Or Not Me.Writeable  Then
            Return False
         Else
            Return True
         End If
      End Get
   End Property
    
   Public Shared Sub DoSomethingSignificant()
   End Sub
    ' Do something significant in here

注解

派生自 NetworkStream 的类可以使用此属性获取基础 Socket。 如果需要超出该属性的访问权限，NetworkStream请使用从Socket该属性返回的基础Socket。

备注

此属性只能通过此类或派生类访问。
