using Info.Blockchain.API.Wallet;

Wallet w = new Wallet("SenderBitCoinAc", "SenderBitCoinAcPwd");

string reciverbitcoinadd = ".PayeerID";

decimal amt = (decimal)(YourAmount);

// this is to convert amt to bitcoin amt formate
decimal finalamt = amt * 100000000;

PaymentResponse pr = w.Send(reciverbitcoinadd , Convert.ToInt64(finalamt));
