以太坊区块链开发-私有链

1.先查看我们两个私链钱包的以太坊wei余额，然后我们将转账写入区块链地址

2.然后我们启动私链 geth --identity "secbro etherum" --rpc --rpccorsdomain "*" --datadir "私链数据文件夹绝对路径" --port "30303" --rpcapi "db,eth, net,web3" --networkid 95518 控制台

然后我们开始码代码以太坊和区块链的不同，我们这里使用Nethereum以太坊开发框架

                var web3 = new Web3(account);//实例化
                await web3.TransactionManager.SendTransactionAsync(account.Address, "0xd8f74f49b638fe0072bad0a177a7b6ff9063368c", new HexBigInteger(1));//发送转账到指定区块链地址单位WeiHexBigInteger(wei))
            }).Wait();
            Console.WriteLine("main end");

            Console.ReadLine();
        }
        public static void ShowWei()
        {//查看钱余额
            var web3 = new Web3();
            var balance = web3.Eth.GetBalance.SendRequestAsync("0x9c086b477028ef6bc7c23efc0ad008982e622f61").Result.Value;
            Console.WriteLine($"Balance in Wei: {balance}");
            var etherAmount = Web3.Convert.FromWei(balance);
            Console.WriteLine($"Balance in Ether: {etherAmount}");

        }
    }
}
