如何使用C#中的zkemkeeper库在图片框中获取运行时的指纹？

using System;
using System.Drawing;
using System.Windows.Forms;
using zkemkeeper;

namespace FingerprintApp
{
    public partial class MainForm : Form
    {
        private CZKEM zkem;

        public MainForm()
        {
            InitializeComponent();
        }

        private void MainForm_Load(object sender, EventArgs e)
        {
            // 实例化zkemkeeper库的对象
            zkem = new CZKEM();
            
            // 连接到指纹识别设备
            bool isConnected = zkem.Connect_Net("192.168.1.100", 4370);
            if (isConnected)
            {
                // 获取指纹图像
                int quality = 50; // 指纹图像质量
                byte[] fingerprintData = null;
                bool isSuccess = zkem.GetRTImage(quality, out fingerprintData);
                if (isSuccess)
                {
                    // 将指纹图像转换为Bitmap对象
                    Bitmap fingerprintImage = ByteArrayToBitmap(fingerprintData);
                    
                    // 在图片框中显示指纹图像
                    pictureBox.Image = fingerprintImage;
                }
                else
                {
                    MessageBox.Show("Failed to get fingerprint image.");
                }
            }
            else
            {
                MessageBox.Show("Failed to connect to the fingerprint device.");
            }
        }

        private Bitmap ByteArrayToBitmap(byte[] byteArray)
        {
            using (var stream = new System.IO.MemoryStream(byteArray))
            {
                return new Bitmap(stream);
            }
        }
    }
}
