var k = new Key(); // создать закрытый ключ
var pubKey = k.PubKey; // получить открытый ключ
KeyId hash = pubKey.Hash; // сформировать часть биткоин-адреса, независимую от сети
BitcoinAddress a = hash.GetAddress(Network.Main); // var a=hash.ScriptPubKey;
Script s = a.ScriptPubKey; // скрипт с опкодами и всё такое
BitcoinSecret WIF=k.GetBitcoinSecret(Network.Main); // WIF format - key in BASE58 encoding

it is possible to get the address from the Script and Network
var s = new Script("OP_DUP OP_HASH160 ff77ae0a6f61fedd8d...");
BitcoinAddress a = s.GetDestinationAddress(Network.Main);
