ClientWebSocket Class

Definition

Provides a client for connecting to WebSocket services.

public ref class ClientWebSocket sealed : System::Net::WebSockets::WebSocket
public sealed class ClientWebSocket : System.Net.WebSockets.WebSocket
type ClientWebSocket = class
    inherit WebSocket
Public NotInheritable Class ClientWebSocket
Inherits WebSocket
Inheritance
ClientWebSocket

Remarks

Some of the classes and class elements in the System.Net.WebSockets namespace are supported on Windows 7, Windows Vista SP2, and Windows Server 2008. However, the only public implementations of client and server WebSockets are supported on Windows 8 and Windows Server 2012. The class elements in the System.Net.WebSockets namespace that are supported on Windows 7, Windows Vista SP2, and Windows Server 2008 are abstract class elements. This allows an application developer to inherit and extend these abstract class classes and class elements with an actual implementation of client WebSockets.

Exactly one send and one receive is supported on each ClientWebSocket object in parallel. Issuing multiple sends or multiple receives at the same time (for example, without awaiting, or from multiple threads without synchronization) is not supported and will result in an undefined behavior. Ensure that the previous operation is awaited (or completed) before issuing the next one. You should serialize the access via whatever mechanism works best for you, for example, by using a lock or a semaphore.

Constructors

ClientWebSocket()

Creates an instance of the ClientWebSocket class.

Properties

CloseStatus

Gets the reason why the close handshake was initiated on ClientWebSocket instance.

CloseStatusDescription

Gets a description of the reason why the ClientWebSocket instance was closed.

HttpResponseHeaders

Gets (if CollectHttpResponseDetails is set) or sets the upgrade response headers.

HttpStatusCode

Gets the upgrade response status code if CollectHttpResponseDetails is set.

Options

Gets the WebSocket options for the ClientWebSocket instance.

State

Gets the WebSocket state of the ClientWebSocket instance.

SubProtocol

Gets the supported WebSocket sub-protocol for the ClientWebSocket instance.

Methods
