// get the jetton wallet address using TonClient: TonSdk.Client
Address jettonWallet = await tonclient.Jetton.GetWalletAddress(jettonMasterContract, address);

// create transfer options
JettonTransferOptions options = new JettonTransferOptions()
{
    Amount = new Coins(100), // jetton amount to send, for ex 100 jettons
    Destination = new Address("/* receiver wallet address */") // receiver
};

// create a message body for the jetton transfer
Cell jettonTransfer = JettonWallet.CreateTransferRequest(options);

// create a transfer message for the wallet
ExternalInMessage message = wallet.CreateTransferMessage(new[]
{
    new WalletTransfer
    {
        Message = new InternalMessage(new()
        {
            Info = new IntMsgInfo(new()
            {
                Dest = jettonWallet,
                Value = new Coins(0.1) // amount in TONs to send
            }),
            Body = jettonTransfer
        }),
        Mode = 1
    }
