NetworkStream.Writeable Property

Gets a value that indicates whether the NetworkStream is writable.

Namespace:  System.Net.Sockets
Assembly:  System (in System.dll)

protected bool Writeable { get; set; }

Property Value

Type: System.Boolean
true if data can be written to the stream; otherwise, false. The default value is true.

You must derive from the NetworkStream class to use the Writeable property. If Writeable is true, NetworkStream allows calls to the Write method. You can also determine whether a NetworkStream is writable by checking the publicly accessible CanWrite property.

The Writeable property is set when the NetworkStream is initialized.

In the following code example, the CanCommunicate property checks the Writeable property to determine if the NetworkStream is writable.

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;
            }
        }
    }
