NetworkStream.Writeable Property

Definition

Gets a value that indicates whether the NetworkStream is writable.

C#
protected bool Writeable { get; set; }

Property Value

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

Examples

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

C#
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;
            }
        }
    }

Remarks

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.
