C# uses gdal environment configuration (1)

The first way: add it through the nuget package. The latest version is 3.6.3, and the dependency on .net framework is 461.

 First download the gdal.native package in nuget

 After the download is complete, a GdalConfiguration.cs file will be generated in the project, with the configuration file path. Replace the code in this file with the following:

 public static partial class GdalConfiguration
    {
        private static volatile bool _configuredOgr;
        private static volatile bool _configuredGdal;

        /// <summary>
        /// Function to determine which platform we're on
        /// </summary>
        private static string GetPlatform()
        {
            return IntPtr.Size == 4 ? "x86" : "x64";
        }


        /// <summary>
        /// Construction of Gdal/Ogr
        /// </summary>
        static GdalConfiguration()
        {
            var executingAssemblyFile = new Uri(Assembly.GetExecutingAssembly().GetName().CodeBase).LocalPath;
            var executingDirectory = Path.GetDirectoryName(executingAssemblyFile);

            if (string.IsNullOrEmpty(executingDirectory))
                throw new InvalidOperationException("cannot get executing directory");


            var gdalPath = Path.Combine(executingDirectory, "gdal");
            var nativePath = Path.Combine(gdalPath, GetPlatform());

            // Prepend native path to environment path, to ensure the
            // right libs are being used.
            var path = Environment.GetEnvironmentVariable("PATH");
            path = nativePath + ";" + Path.Combine(nativePath, "plugins") + ";" + path;
            Environment.SetEnvironmentVariable("PATH", path);

            // Set the additional GDAL environment variables.
            var gdalData = Path.Combine(gdalPath, "data");
            Environment.SetEnvironmentVariable("GDAL_DATA", gdalData);
            Gdal.SetConfigOption("GDAL_DATA", gdalData);

            var driverPath = Path.Combine(nativePath, "plugins");
            Environment.SetEnvironmentVariable("GDAL_DRIVER_PATH", driverPath);
            Gdal.SetConfigOption("GDAL_DRIVER_PATH", driverPath);

            Environment.SetEnvironmentVariable("GEOTIFF_CSV", gdalData);
            Gdal.SetConfigOption("GEOTIFF_CSV", gdalData);

            var projSharePath = Path.Combine(gdalPath, "share");
            Environment.SetEnvironmentVariable("PROJ_LIB", projSharePath);
            Gdal.SetConfigOption("PROJ_LIB", projSharePath);
        }

        /// <summary>
        /// Method to ensure the static constructor is being called.
        /// </summary>
        /// <remarks>Be sure to call this function before using Gdal/Ogr/Osr</remarks>
        public static void ConfigureOgr()
        {
            if (_configuredOgr) return;

            // Register drivers
            Ogr.RegisterAll();
            _configuredOgr = true;

            PrintDriversOgr();
        }

        /// <summary>
        /// Method to ensure the static constructor is being called.
        /// </summary>
        /// <remarks>Be sure to call this function before using Gdal/Ogr/Osr</remarks>
        public static void ConfigureGdal()
        {
            if (_configuredGdal) return;

            // Register drivers
            Gdal.AllRegister();
            _configuredGdal = true;

            PrintDriversGdal();
        }

        private static void PrintDriversOgr()
        {
#if DEBUG
            var num = Ogr.GetDriverCount();
            for (var i = 0; i < num; i++)
            {
                var driver = Ogr.GetDriver(i);
                Console.WriteLine(string.Format("OGR {0}: {1}", i, driver.name));
            }
#endif
        }

        private static void PrintDriversGdal()
        {
#if DEBUG
            var num = Gdal.GetDriverCount();
            for (var i = 0; i < num; i++)
            {
                var driver = Gdal.GetDriver(i);
                Console.WriteLine(string.Format("GDAL {0}: {1}-{2}", i, driver.ShortName, driver.LongName));
            }
#endif
        }
    }

Test it: calling method

            GdalConfiguration.ConfigureGdal();
            GdalConfiguration.ConfigureOgr();
           // Ogr.RegisterAll();
            Geometry geom = Geometry.CreateFromWkt("POINT(47.0 19.2)");

The above string of calling codes is executed successfully even if the environment configuration is successful.
