An explanation of the operations in the ASP. NET SignalR Hub class

Operations in the Hub class

On the server we're going to do a series of operations through the hub class, so let's talk about what we can do.

Send Message operation for client

Call the Helloclient method for all clients

Clients.All.helloClient ();

Call the Helloclient method for all clients except for a given ConnectionID client

Clients.allexcept (Context.connectionid). Helloclient ();

Invokes the Helloclient method of the specified ConnectionID client

Clients.client (Context.connectionid). Helloclient ();

Calls the Helloclient method to the client of the specified ConnectionID collection

Clients.clients (New list<string> () {"Client1", "Client2"}). Helloclient ();

Invokes all client helloclient methods in a group with the specified name, this method has overloads and can specify the excluded ConnectionID

Clients.group ("Room1"). Helloclient ();

Invokes the Helloclient method for all clients of the specified group collection, which has overloads that can specify the excluded ConnectionID

Clients.groups (New list<string> () {"Room1", "Room2"}). Helloclient ();

Group operations

Remember that in a persistent connection class, you can add members to a group and delete members, which you can do in a hub.

Add action

Groups.add (this. Context.connectionid, "room1");

Delete operation

Groups.remove (this. Context.connectionid, "room1");

Note: User and users in clients are not explained because they are related to authentication and are left to the post for further explanation.
