openhardwaremonitor get only GPU temp

Question

I am trying to get my (nvidia) GPU temperature reading from a c# project. There is already a solution for that, using openhardwaremonitor dll file.

This is my code :

using OpenHardwareMonitor.Hardware;

...

Computer myComputer = new Computer();
myComputer.GPUEnabled = true;
myComputer.Open();

foreach (var hardwareItem in myComputer.Hardware)
{
    if (hardwareItem.HardwareType == HardwareType.GpuNvidia)
    {     
       foreach (var sensor in hardwareItem.Sensors)
       {
           Console.WriteLine(sensor.Identifier.ToString() + ":" + sensor.Value.ToString());
       }                   
    }
}

This results in the following output:

/nvidiagpu/0/clock/0:
/nvidiagpu/0/clock/1:
/nvidiagpu/0/clock/2:
/nvidiagpu/0/load/3:1.324463

This is a code to get a full hardware report:

Computer myComputer = new Computer();
myComputer.GPUEnabled = true;
myComputer.Open();
Console.Write(myComputer.GetReport());

This is what i got in return :

As you can see the temperature reading is there , but i could not find a way to get it programmatically. Obviously i can parse the returned string and get the temperature reading, but i would feel really bad doing it.

Would be happy to get any insight on this.

I think you have already found a solution. If not, then here is the code.

foreach (var sensor in hardwareItem.Sensors)
{
    if (sensor.SensorType == SensorType.Temperature)
    {
        Console.WriteLine(sensor.Value.ToString());
        Console.WriteLine(sensor.Identifier.ToString() + ":" + sensor.Value.ToString());
    }
}
