在这个教程中,我们将使用C#来开发一个比特币钱包,我们使用NBitcoin这个库。教程中的代码实现了比特币的存储、接收和支付功能,可以很容易地移植到其他应用中。如果要快速掌握NBitcoin的使用方法,推荐访问汇智网的课程:
我们要开发的比特币钱包要实现以下功能:
首先需要引入NBitcoin开发包以及QBitNinja开发包:
using NBitcoin;
using QBitNinja.Client;
using QBitNinja.Client.Models;
我们需要保存下来生成的助记词:
public void MssGenerateMnemo(out string ssMnemo) {
Mnemonic mnemonic = new Mnemonic(Wordlist.English, WordCount.Twelve);
ssMnemo = mnemonic.ToString();
}
下面的代码可以利用NBitcoin生成比特币HD地址:
public void MssGenerateAddress(
string ssMnemo,
int ssKeynumber,
bool ssIsTestNet,
out string ssAddress,
out string ssPrivateKey) {
Network net;
if (ssIsTestNet)
net = Network.TestNet;
else
net = Network.Main;
Mnemonic restoreNnemo = new Mnemonic(ssMnemo);
ExtKey masterKey = restoreNnemo.DeriveExtKey();
KeyPath keypth = new KeyPath("m/44‘/0‘/0‘/0/" + ssKeynumber);
ExtKey key = masterKey.Derive(keypth);
ssAddress = key.PrivateKey.PubKey.GetAddress(net).ToString();
ssPrivateKey = key.PrivateKey.GetBitcoinSecret(net).ToString();
}
下面的代码可以获取指定地址的比特币余额:
public void MssGetBalance(
string ssAddress,
bool ssIsUnspentOnly,
bool ssIsTestNet,
out decimal ssBalance,
out decimal ssConfirmedBalance) {
Network net;
if (ssIsTestNet)
net = Network.TestNet;
else
net = Network.Main;
QBitNinjaClient client = new QBitNinjaClient(net);
var balance = client.GetBalance(new BitcoinPubKeyAddress(ssAddress), ssIsUnspentOnly).Result;
ssBalance = 0.0M;
ssConfirmedBalance = 0.0M;
if (balance.Operations.Count > 0)
{
var unspentCoins = new List<Coin>();
var unspentCoinsConfirmed = new List<Coin>();
foreach (var operation in balance.Operations)
{
unspentCoins.AddRange(operation.ReceivedCoins.Select(coin => coin as Coin));
if(operation.Confirmations > 0)
unspentCoinsConfirmed.AddRange(operation.ReceivedCoins.Select(coin => coin as Coin));
}
ssBalance = unspentCoins.Sum(x => x.Amount.ToDecimal(MoneyUnit.BTC));
ssConfirmedBalance = unspentCoinsConfirmed.Sum(x => x.Amount.ToDecimal(MoneyUnit.BTC));
}
}
下面的代码可以利用NBitcoin实现向指定的地址转账比特币:
public void MssGetBalance(
string ssAddress,
bool ssIsUnspentOnly,
bool ssIsTestNet,
out decimal ssBalance,
out decimal ssConfirmedBalance) {
Network net;
if (ssIsTestNet)
net = Network.TestNet;
else
net = Network.Main;
QBitNinjaClient client = new QBitNinjaClient(net);
var balance = client.GetBalance(new BitcoinPubKeyAddress(ssAddress), ssIsUnspentOnly).Result;
ssBalance = 0.0M;
ssConfirmedBalance = 0.0M;
if (balance.Operations.Count > 0)
{
var unspentCoins = new List<Coin>();
var unspentCoinsConfirmed = new List<Coin>();
foreach (var operation in balance.Operations)
{
unspentCoins.AddRange(operation.ReceivedCoins.Select(coin => coin as Coin));
if(operation.Confirmations > 0)
unspentCoinsConfirmed.AddRange(operation.ReceivedCoins.Select(coin => coin as Coin));
}
ssBalance = unspentCoins.Sum(x => x.Amount.ToDecimal(MoneyUnit.BTC));
ssConfirmedBalance = unspentCoinsConfirmed.Sum(x => x.Amount.ToDecimal(MoneyUnit.BTC));
}
}
