Question

我正在尝试从服务器将Hex文件上传到UNO模块。 代码已成功上传到localhost中的UNO ，当我在godaddy服务器上托管时，它给出了一个错误如何解决？

using ArduinoUploader;
using ArduinoUploader.Hardware;
using System;
using System.IO.Ports;
namespace AmpliBurn
{
    public partial class index : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            string[] arr = SerialPort.GetPortNames();
            DropDownList2.Items.Clear();

            foreach (var item in arr)
            {
               DropDownList2.Items.Add(item); 
            }
        }



        public void read(string aPath)
        {
          //  string content = File.ReadAllText(aPath);
          //  Label4.Text = content;
        }

        protected void Button1_Click(object sender, EventArgs e)
        {

            try
            {
                String fname;
                fname = Server.MapPath(DropDownList1.SelectedValue.ToString());
                read(fname);
                var uploader = new ArduinoSketchUploader(
               new ArduinoSketchUploaderOptions()
               {
                   FileName = fname,
                   PortName = DropDownList2.SelectedItem.Text,
                   ArduinoModel = ArduinoModel.UnoR3
               });
                uploader.UploadSketch();  // error in this line
                Label3.Text = "Success";
            }

            catch (Exception exception )
            {
                Label3.Text= exception.InnerException + "_" + exception.Message + "//" + exception.StackTrace;
                //System.IO.File.WriteAllText(AppDomain.CurrentDomain.BaseDirectory+ "/Excception.txt", exception.InnerException+"_"+exception.Message+"//"+exception.StackTrace);
            }
        }
    }
}

错误：

通过方法'RJCP.IO.Ports.Native.WinNativeSerial.get_IsOpen（）'进行尝试访问字段'RJCP.IO.Ports.Native.WinNativeSerial.m_ComPortHandle' 失败。//在以下位置的RJCP.IO.Ports.Native.WinNativeSerial.get_IsOpen（） c：\ Users \ jcurl \ Documents \ Programming \ HELIOS \ serialportstream \ code \ Native \ WinNativeSerial.cs：line RJCP.IO.Ports.Native.WinNativeSerial.Dispose（布尔处理）处的643 在 c：\ Users \ jcurl \ Documents \ Programming \ HELIOS \ serialportstream \ code \ Native \ WinNativeSerial.cs：line 1070在RJCP.IO.Ports.Native.WinNativeSerial.Dispose（）中 c：\ Users \ jcurl \ Documents \ Programming \ HELIOS \ serialportstream \ code \ Native \ WinNativeSerial.cs：line 1058在RJCP.IO.Ports.SerialPortStream.GetPortNames（）中 c：\ Users \ jcurl \ Documents \ Programming \ HELIOS \ serialportstream \ code \ SerialPortStream.cs：line 319点 ArduinoUploader.ArduinoSketchUploader.UploadSketch（IEnumerable`1 hexFileContents）在 ArduinoUploader.ArduinoSketchUploader.UploadSketch（）位于 AmpliBurn.index.Button1_Click（Object sender，EventArgs e）在 C：\ Users \ Sutirtha Z Innocent \ source \ repos \ AmpliBurn \ AmpliBurn \ index.aspx.cs：第46行

我们可以从服务器在线将Arduino Hex代码上传到UNO板上吗？
