# OBD.NET
C#-Library to read/write data from/to a car through an ELM327-/STN1170-Adapter

## Projects
* [OBD.NET](https://www.nuget.org/packages/OBD.NET) - OBD-II implementation in .NET 6/5 and .NET Framework 4.8
* ConsoleClient - Example client application using SerialConnection, running with .NET 6

## Usage
* Add the `OBD.NET` package to project
```csharp

public class Program
{
    public static void Main(string[] args)
    {
        if (args.Length < 1)
        {

            Console.WriteLine("\nAvailable ports:");

            foreach (string port in availablePorts)
            {
                Console.WriteLine(port);
