modbus - 在我的 Modbus Console.WriteLine 中查找错误

Question

我有这个 C# 代码，它正在产生一个错误Console.WriteLine($"Register {startAddress + i}={registers[i]}");。我试过 double ))，并将它放在声明中的任何地方。我根本看不到错误在哪里。我可能错过了一些简单的东西，我只是没有看到它。

    namespace NModbus.TestDriver

{
    using System;
    using System.Net.Sockets;
    using Modbus.Device;
    using NModbus;


    class Program
    {
        static void Main(string[] args)
        {
                         using (TcpClient client = new TcpClient("192.168.111.169", 502))
                {
                    client.Client.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.KeepAlive, true);

                    var master = ModbusIpMaster.CreateIp(client);
                    // read five input values
                  byte slaveId = 1;
                ushort startAddress = 1;
                ushort numRegisters = 5;

                // read five registers      
                ushort[] registers = master.ReadHoldingRegisters(slaveId, startAddress, numRegisters);

                for (int i = 0; i < numRegisters; i++)
                {
                    Console.WriteLine($"Register {startAddress + i}={registers[i]}");
                }
            }
        }
    }
}

尝试在执行之前定义字符串Console.WriteLine——所以 for 循环是这样的

             for (int i = 0; i < numRegisters; i++)
                {
                    string whateverName = $"Register {startAddress + i}={registers[i]}"
                    Console.WriteLine(whateverName);
                }
