在我的 Modbus Console.WriteLine 中查找错误

问题描述

我有这个 C# 代码，它在 Console.WriteLine($"Register {startAddress + i}={registers[i]}"); 行产生错误。我试过双 ))，并将它放在语句中的任何地方。我根本看不出错误在哪里。我可能遗漏了一些简单的东西，只是我没有看到。

    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]}");
                }
            }
        }
    }
}

解决方法

在做 Console.WriteLine 之前尝试定义字符串——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);
                }
