C# quick integration

1. C# quick integration

Since our library is developed in C++, it cannot be called directly through functions in interface.h. Instead, we need to use the DllImport attribute to declare the prototype of the C function and define the implementation of the function using the extern keyword.

Here is a simple example:

using System;
using System.Runtime.InteropServices;

class Program
{
    // Declare the prototype of the connect_robot function
    [DllImport("libnrc_host.dll")]
    public static extern int connect_robot(string ip, string port, string robotName);

    // Declare the prototype of the get_current_position function
    [DllImport("RobotLibrary.dll")]
    public static extern int get_current_position(double[] pos, int coord, string robotName);

    static void Main()
    {
        // Call the connect_robot function
        int result = connect_robot("192.168.1.13", "6001", "RobotA");

        // Check the connection result
        if (result == 0)
        {
            Console.WriteLine("Connection successful!");
        }
        else
        {
            Console.WriteLine("Connection failed!");
        }
        // Create an array to store the position information
        double[] currentPosition = new double[7];

        // Call the get_current_position function
        int result = get_current_position(currentPosition, 1, "RobotA");

        // Check the result of retrieving the position
        if (result == 0)
        {
            Console.WriteLine("Successfully retrieved current position:");
            Console.WriteLine($"X: {currentPosition[0]}, Y: {currentPosition[1]}, Z: {currentPosition[2]}");
        }
        else
        {
            Console.WriteLine("Failed to retrieve current position!");
        }
    }
}
