NetworkStream.Readable Property

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

true to indicate that the NetworkStream can be read; otherwise, false. The default value is true.

In the following code example, the CanCommunicate property checks the Readable property to determine if the NetworkStream is readable.

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;

        }

You must derive from the NetworkStream class to use the Readable property. If Readable is true, NetworkStream allows calls to the Read method. You can also determine whether a NetworkStream is readable by checking the publicly accessible CanRead property.

The Readable property is set when the NetworkStream is initialized.

• CanRead
• CanWrite
• Writeable
