Nethereum C#自动乙醚转移

Question

我希望自动将以太传输到一个人员列表。假设列表在csv中。我写了一些代码来自动化这个过程。

class Program
{
int nonce = 0;
static void Main(string[] args)
{
var account = SetupAccount();
var recipients = ReadCsv();
var web3Init = GetConnection();
nonce = web3.Eth.Transactions.GetTransactionCount.SendRequestAsync(account.Address).Result;
//var recipients = new List<Records>() { new Records() { Value = 10000000000000000, Address = "0x5CC494843e3f4AC175A5e730c300b011FAbF2cEa" } };
foreach (var recipient in recipients)
{
try
{
var web3 = GetConnection();
var receipt = SendEther(account, recipient, web3).Result;
}
catch (System.Exception)
{
MessageBox.Show("Failed");                                        
}
Thread.Sleep(30000);
}
}
private static async Task<TransactionReceipt> SendEther(Account account, Records recipient, Web3 web3)
{
var transactionPolling = web3.TransactionManager.TransactionReceiptService;
//var currentBalance = await web3.Eth.GetBalance.SendRequestAsync(account.Address);
//assumed client is mining already
//when sending a transaction using an Account, a raw transaction is signed and send using the private key
return await transactionPolling.SendRequestAndWaitForReceiptAsync(() =>
{
var transactionInput = new TransactionInput
{
From = account.Address,
//Gas = new HexBigInteger(25000),
GasPrice = new HexBigInteger(10 ^ 10),
To = recipient.Address,
Value = new HexBigInteger(new BigInteger(recipient.Value)),
Nonce = nonce
};
var txSigned = new Nethereum.Signer.TransactionSigner();
var signedTx = txSigned.SignTransaction(account.PrivateKey, transactionInput.To, transactionInput.Value, transactionInput.Nonce);
var transaction = new Nethereum.RPC.Eth.Transactions.EthSendRawTransaction(web3.Client);
nonce++;
return transaction.SendRequestAsync(signedTx);
});
}
private static Web3 GetConnection()
{
return new Web3("https://mainnet.infura.io");
}
private static Account SetupAccount()
{
var password = "@Password";
var accountFilePath = @"filePath";
return Account.LoadFromKeyStoreFile(accountFilePath, password);
}
private static List<Records> ReadCsv()
{
string filePath = @"C:UsersPottisourcereposConversionFilesXrcfRecipients.csv";
if (File.Exists(filePath))
{
using (StreamReader stream = new StreamReader(filePath))
{
CsvReader reader = new CsvReader(stream, new Configuration
{
TrimOptions = TrimOptions.Trim,
HasHeaderRecord = true,
HeaderValidated = null
});
reader.Configuration.RegisterClassMap<RecordMapper>();
return reader.GetRecords<Records>().ToList();
}
}
else
{
return null;
}
}
}
class Records
{
public string Address { get; set; }
public decimal Value { get; set; }
}
sealed class RecordMapper : ClassMap<Records>
{
public RecordMapper()
{
Map(x => x.Address).Name("Address");
Map(x => x.Value).Name("Value");
}
}

如何修改流程以一次执行所有事务，而不是等待每个事务完成？(点燃并忘记(此外，这样做是否有任何安全考虑？

Answer 1

您当前正在做的是等待挖掘每个事务。您可以做以下操作：

var account = new Account("privateKey"); // or load it from your keystore file as you are doing.
var web3 = new Web3(account, "https://mainnet.infura.io");

首先使用相同的Account对象创建一个web3实例，因为我们使用的是带有私钥的帐户，Nethereum会在发送交易之前对其进行离线签名。

现在使用TransactionManager，您可以为每个接收发送一个事务

var transactionHashes = new List<string>();
foreach(var recepient in recepients){
var transactionInput = new TransactionInput
{
From = account.Address,
GasPrice = Web3.Convert.ToWei(1.5, UnitConversion.EthUnit.Gwei);,
To = recipient.Address,
Value = new HexBigInteger(new BigInteger(recipient.Value)),
};
var transactionHash = web3.Eth.TransactionManager.SendTransactionAsync(transactionInput);
transanctionHashes.Add(transactionHash);
}

请注意，当Nethereum使用相同的Account和TransactionManager实例(在这种情况下为Web3(时，它会创建一个默认的NonceMemoryService，因此您不需要跟踪您的nonce(交易编号(来签署交易。

此外，我已经将GasPrice从Gwei转换为Wei，作为单位转换的一个例子，我假设您已经将要发送的以太币金额转换为Wei。

最后，另一个注意事项是，为了进一步简化这一点，即将推出的EtherTransferService允许您输入以太币金额和Gwei价格金额，以避免进行转换。此外，如果没有传递任何参数，将为您计算天然气价格。

web3.Eth.GetEtherTransferService().TransferEtherAsync("toAddress", EtherAmount);
