How to convert BMP to GIF in C#

public static void BitmapToGIF(string BitmapFile, string GIFFile)
{
    using (Bitmap bitMap = new Bitmap(BitmapFile))
    {
            //var codecInfo = GetEncoderInfo(ImageFormat.Gif);
            var codecInfo = ImageCodecInfo.GetImageEncoders().FirstOrDefault(x => x.FormatID == ImageFormat.Gif.Guid);

            using (var paramsEncoder = new EncoderParameters(2))
            {
                paramsEncoder.Param[0] = new EncoderParameter(System.Drawing.Imaging.Encoder.Compression, (long)EncoderValue.CompressionLZW);
                paramsEncoder.Param[1] = new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, 0L);
                bitMap.Save(GIFFile, codecInfo, paramsEncoder);
            }
    }
