NetworkStream.Readable Properti

Definisi

Ruang nama:

System.Net.Sockets

Rakitan:

System.Net.Sockets.dll

Sumber:

NetworkStream.cs

Mendapatkan atau menetapkan nilai yang menunjukkan apakah NetworkStream dapat dibaca.

protected:
 property bool Readable { bool get(); void set(bool value); };

protected bool Readable { get; set; }

member this.Readable : bool with get, set

Protected Property Readable As Boolean

Nilai Properti

Boolean

true untuk menunjukkan bahwa NetworkStream dapat dibaca; jika tidak, false. Nilai defaultnya adalah true.

Contoh

Dalam contoh kode berikut, CanCommunicate properti memeriksa Readable properti untuk menentukan apakah NetworkStream dapat dibaca.

#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;
            }
        }
    }

   Inherits NetworkStream

      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

Keterangan

Anda harus berasal dari NetworkStream kelas untuk menggunakan Readable properti . Jika Readable adalah true, NetworkStream memungkinkan panggilan ke Read metode . Anda juga dapat menentukan apakah dapat NetworkStream dibaca dengan memeriksa properti yang dapat diakses CanRead publik.

Properti Readable diatur ketika diinisialisasi NetworkStream .
