在官網下載安裝DataMan設置工具，連接掃碼槍后進行設置曝光，焦距等...

在該路徑中C:\Program Files (x86)\Cognex\DataMan\DataMan Software v6.1.10_SR3，找到Cognex.DataMan.SDK.PC.dll 文件，在項目中添加該文件引用

在類中添加引用：using Cognex.DataMan.SDK;

//申明連接對象 EthSystemConnector myConn; DataManSystem _system; //連接方法 private void btnConnect_Click(object sender, RoutedEventArgs e){try{//設置ipIPAddress deviceIP = IPAddress.Parse(textBox1.Text.Trim());myConn = new EthSystemConnector(deviceIP);_system = new DataManSystem(myConn);//設置掃描類型，圖片，文字等ResultTypes requested_result_types = ResultTypes.ReadString| ResultTypes.Image | ResultTypes.ImageGraphics;// 讀取文字事件_system.ReadStringArrived += _system_ReadStringArrived;//獲取圖像事件_system.ImageArrived += _system_ImageArrived;_system.Connect();_system.SetResultTypes(requested_result_types);}catch (Exception ex){MessageBox.Show(ex.Message);}} private void _system_ReadStringArrived(object sender, ReadStringArrivedEventArgs args){string str = args.ReadString;} private void _system_ImageArrived(object sender, ImageArrivedEventArgs args){Image img = args.Image;}

斷開連接

private void button1_Click(object sender, RoutedEventArgs e){if (_system != null){_system.Disconnect();}}

觸發

private void btnTrigger_Click(object sender, RoutedEventArgs e){if (_system != null){_system.SendCommand("TRIGGER ON");}}

最簡單的連接觸發與關閉，只用到一個dll，更多屬性和事件就先不說了
