I want to access the OpenHardwareMonitor DLL file with node.js using the edge.js module and monitor the computer's CPU and GPU temperatures. I created a C# console application in Visual Studio and added the DLL file to the references. When I ran the Program.cs file below, I successfully reached the CPU temperature.
Program.cs;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using OpenHardwareMonitor.Hardware;
namespace Get_CPU_Temp5
{
class Program
{
public class UpdateVisitor : IVisitor
{
public void VisitComputer(IComputer computer)
{
computer.Traverse(this);
}
public void VisitHardware(IHardware hardware)
{
hardware.Update();
foreach (IHardware subHardware in hardware.SubHardware) subHardware.Accept(this);
}
public void VisitSensor(ISensor sensor) { }
public void VisitParameter(IParameter parameter) { }
}
static void GetSystemInfo()
{
UpdateVisitor updateVisitor = new UpdateVisitor();
Computer computer = new Computer();
computer.Open();
computer.CPUEnabled = true;
computer.Accept(updateVisitor);
for (int i = 0; i < computer.Hardware.Length; i++)
{
if (computer.Hardware[i].HardwareType == HardwareType.CPU)
{
for (int j = 0; j < computer.Hardware[i].Sensors.Length; j++)
{
if (computer.Hardware[i].Sensors[j].SensorType == SensorType.Temperature)
Console.WriteLine(computer.Hardware[i].Sensors[j].Name + ":" + computer.Hardware[i].Sensors[j].Value.ToString() + "\r");
}
}
}
computer.Close();
}
static void Main(string[] args)
{
while (true)
{
GetSystemInfo();
}
}
}
}
I want to run the same code in my Nodejs project with edge.js and access the CPU temperature. I tried this but I've got errors. I checked the datatype of computer.Hardware[i].Sensors[j].Value . It's called System.Single. I think I need a return value but I don't quite understand how to do it.
I'm not sure where I went wrong. I will be glad if you help
var edge = require('edge-js');
var add7 = edge.func({
source: function() {/*
using System;
using System.Data;
using System.Threading.Tasks;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using OpenHardwareMonitor.Hardware;
public class Startup
{
public async Task<object> Invoke(object input)
{
Computer computer = new Computer() ;
computer.Open();
computer.CPUEnabled = true ;
for(int i = 0 ; i<computer.Hardware.Length;i++){
if(computer.Hardware[i].HardwareType == HardwareType.CPU){
for(int j = 0 ; j< computer.Hardware[i].Sensors.Length;j++){
if(computer.Hardware[i].Sensors[j].SensorType == SensorType.Temperature)
Console.WriteLine(computer.Hardware[i].Sensors[j].Name + ":" + computer.Hardware[i].Sensors[j].Value.ToString()+"\r");
}
}
}
computer.Close();
}
}
*/},
references: [ 'System.Data.dll' ,'OpenHardwareMonitorLib.dll' ]
//references: [ 'OpenHardwareMonitorLib.dll' ],
});
And this is the error;
return edge.initializeClrFunc(options);

--EDIT--
When I tried this ;
public class Startup
{
public class UpdateVisitor : IVisitor
{
public void VisitComputer(IComputer computer)
{
computer.Traverse(this);
}
public void VisitHardware(IHardware hardware)
{
hardware.Update();
foreach (IHardware subHardware in hardware.SubHardware) subHardware.Accept(this);
}
public void VisitSensor(ISensor sensor) { }
public void VisitParameter(IParameter parameter) { }
}
public async Task<object> Invoke(object _)
{
while (true)
{
GetSystemInfo();
return await Task.FromResult<object>(null);
}
}
static void GetSystemInfo()
{
UpdateVisitor updateVisitor = new UpdateVisitor();
Computer computer = new Computer();
computer.Open();
computer.CPUEnabled = true;
computer.Accept(updateVisitor);
for (int i = 0; i < computer.Hardware.Length; i++)
{
if (computer.Hardware[i].HardwareType == HardwareType.CPU)
{
for (int j = 0; j < computer.Hardware[i].Sensors.Length; j++)
{
if (computer.Hardware[i].Sensors[j].SensorType == SensorType.Temperature)
Console.WriteLine(computer.Hardware[i].Sensors[j].Name + ":" + computer.Hardware[i].Sensors[j].Value.ToString() + "\r");
}
}
}
computer.Close();
}
}
I got this error;
CS5001 Program does not contain a static Main method suitable for an entry point
I also tried ;
public async Task Invoke(object _)
{
while (true)
{
GetSystemInfo();
return await Task.FromResult<object>(null);
}
}
And it says;
Since 'Startup.Invoke(object)' is an async method that returns 'Task', a return keyword must not be followed by an object expression. Did you intend to return 'Task<T>'?
