C# Winform怎么设计串口,客户端和相机控件界面显示

 首先我们必须把这个类创建好

窗体加载,想让一些数据附在文本框中

Total total = Total.Instance();private void Form4_Load(object sender, EventArgs e){total.LoadCamera();checkBox2.Checked = total.TcpOpen == 1 ? true : false;IPtxt.Text = total.TcpIP;Porttxt.Text = total.TcpPort.ToString();total.LoadSerial();checkBox1.Checked = total.Serialopen == 1 ? true : false;portname.Text = total.Serialname;baudrate.Text = total.Serialbaudrate.ToString();fixture.Text = total.Serialfixture.ToString();databits.Text = total.Serialdata.ToString();stopbits.Text = total.Serialstop.ToString();}

TCP和Serial的保存

 private void button2_Click(object sender, EventArgs e){total.TcpOpen = checkBox2.Checked ? 1 : 0;total.TcpIP = IPtxt.Text;total.TcpPort = int.Parse(Porttxt.Text);IniAPI.INIWriteValue(total.Tcppath, "TCP的参数", "是否开启", total.TcpOpen.ToString());IniAPI.INIWriteValue(total.Tcppath, "TCP的参数", "IP地址", total.TcpIP);IniAPI.INIWriteValue(total.Tcppath, "TCP的参数", "端口号", total.TcpPort.ToString());MessageBox.Show("保存成功");}private void button1_Click(object sender, EventArgs e){total.Serialopen = checkBox1.Checked ? 1 : 0;total.Serialname = portname.Text;total.Serialbaudrate = Convert.ToInt32(baudrate.Text);total.Serialfixture = fixture.Text;total.Serialdata = Convert.ToInt32(databits.Text);total.Serialstop = stopbits.Text;IniAPI.INIWriteValue(total.Serialpath, "串口的参数", "是否开启", total.Serialopen.ToString());IniAPI.INIWriteValue(total.Serialpath, "串口的参数", "名称", total.Serialname);IniAPI.INIWriteValue(total.Serialpath, "串口的参数", "波特率", total.Serialbaudrate.ToString());IniAPI.INIWriteValue(total.Serialpath,"串口的参数","校验位",total.Serialfixture);IniAPI.INIWriteValue(total.Serialpath,"串口的参数","数据位",total.Serialdata.ToString());IniAPI.INIWriteValue(total.Serialpath,"串口的参数","停止位",total.Serialstop);MessageBox.Show("保存成功");}

相机参数显示--先搭好界面
