首先，在C#中要使用Arduino Mouse库，需要先下载并安装Arduino IDE。接下来，将下列代码保存为MouseClick.ino文件并上传到Arduino板子上：

#include "Mouse.h"

void setup() { pinMode(2, INPUT_PULLUP); }

void loop() { // read the pushbutton: int buttonState = digitalRead(2); // if the button is pressed: if (buttonState == LOW) { // move the mouse: Mouse.move(0, 40); // click the left button: Mouse.click(); } delay(50); }

然后，在C#中编写以下代码来调用Mouse.Click功能：

//引用Microsoft.VisualBasic.dll类库 //引用Windows.Forms.dll类库 //引用System.IO.Ports.dll类库 using System.IO.Ports; using System.Threading; using System.Windows.Forms;

namespace ArduinoMouseClickDemo { public partial class Form1 : Form { private SerialPort port;

    public Form1()
    {
        InitializeComponent();
        //初始化串口
        port = new SerialPort();
        port.PortName = "COM3";//串口号，需与Arduino板子连接的口一致
        port.BaudRate = 9600;//比特率
        port.DataBits = 8;
        port.StopBits = StopBits.One;
        port.Parity = Parity.None;
        port.Open();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        //发送到串口中，开启鼠标点击操作
        port.Write("A");
    }

    private void button2_Click(object sender, EventArgs e)
    {
        //发送到串口中，关闭鼠标点击操作
        port.Write("B");
    }

    private void button3_Click(object sender, EventArgs e)
    {
        //发送到串口中，启用鼠标移动
        port.Write("C");
    }

    private void button4_Click(object sender, EventArgs e)
    {
        //发送到串口中，关闭鼠标移动
        port.Write("D");
    }

    private void Form1_KeyPress(object sender, KeyPressEventArgs e
