SendingNetwork DotNet SDK

A DotNet SDK for SendingNetwork.

Supported Platforms

• .NET Standard 2.0 or greater

Installation

Add dependency

dotnet add package SDN.Sdk

Use the SDK in your app

1. Create

Use SDNClientFactory to create an instance of SDNClient

var factory = new SDNClientFactory();
ISDNClient client = factory.Create();

2.Login

Currently, SDNClient supports only wallet account login

// pre login
var preLoginResponse = await client.PreLoginAsync(new Uri(nodeUrl), walletAddress);

// sign message (or prompt user to sign with a wallet app)
var signer = new EthereumMessageSigner();
var signature = signer.EncodeUTF8AndSign(preLoginResponse.Message, new EthECKey(privateKey));

// login did
var loginResponse = await client.LoginAsync(preLoginResponse.Did, preLoginResponse.RandomServer, preLoginResponse.Updated, preLoginResponse.Message, signature);
                userId = loginResponse.UserId;
                accessToken = loginResponse.AccessToken;

// set client credential
client.SetCredential(new Uri(nodeUrl), loginResponse.UserId, loginResponse.AccessToken);

3. Start listening for incomming events

To listen for the incoming room events you need to subscribe to OnSDNRoomEventsReceived;

// add event listener
client.OnSDNRoomEventsReceived += (sender, eventArgs) =>
{
    foreach (var roomEvent in eventArgs.SDNRoomEvents)
    {
        if (roomEvent is TextMessageEvent textMessageEvent)
        {
            Console.WriteLine($"RoomId: {textMessageEvent.RoomId} received event from {textMessageEvent.SenderUserId}: {textMessageEvent.Message}.");
        }
    }
};

// start syncing
client.Start();

4. Call API functions

// create new room
await client.CreateRoomAsync(roomName, null);

// invite user to the room
await client.InviteUserAsync(roomId, userId);

// send room message
await client.SendMessageAsync(roomId, "hello");
