C#安装NuGet、安装NModbus4

本文主要是介绍C#安装NuGet、安装NModbus4，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

C#安装：

using Modbus.Device;
using Modbus.Utility;
//using Modbus.Serial;namespace Modbus
{public partial class Form1 : Form{public Form1(){InitializeComponent();}private void Form1_Load(object sender, EventArgs e){using (SerialPort port = new SerialPort("COM1")){// configure serial portport.BaudRate = 9600;port.DataBits = 8;port.Parity = Parity.None;port.StopBits = StopBits.One;port.Open();//var adapter = new SerialPortAdapter(port);// create modbus masterIModbusSerialMaster master = ModbusSerialMaster.CreateRtu(port);byte slaveId = 1;ushort startAddress = 100;ushort[] registers = new ushort[] { 1, 2, 3 };// write three registersmaster.WriteMultipleRegisters(slaveId, startAddress, registers);//读取数据函数：slaveId = 1;startAddress = 0;ushort numRegisters = 10;             registers = master.ReadHoldingRegisters(slaveId, startAddress, numRegisters);//读取寄存器数据到register数组中//需要处理数据的话 后面可能就需要数据的转化//写数据函数：byte slaveID = 1;ushort registerAddress = 0;ushort value = 100;//你要写的值master.WriteSingleRegister(slaveID, registerAddress, value);}}}
}

安装完NuGet，重启VS，在Tool里面找到Nuget下得console，然后输入：

PM > Install-Package NModbus4

不通过nuget在线下载，比较慢

可以在https://www.nuget.org/packages/NModbus4/2.1.0下，下载需要的包，

需要设置VS的nuget源为本地，也就是你下载的包的路径，并且需要放在最上面，否则找不到，如下

包名一般是如下：

红框内是安装方法，
