C# Image GPS location property disappears after resizing image

Question

When I resize an image using the method below, the GPS location(latitude-longitude) disappears for the resized image. how can I save it with the original GPS information.

private void ResizeImage(Image imgPhoto, int Width, int Height, string targetPath)
    {
        int sourceWidth = imgPhoto.Width;
        int sourceHeight = imgPhoto.Height;
        int X = 0; int Y = 0; float nPercent = 0; float nPercentW = 0; float nPercentH = 0;
        nPercentW = ((float)Width / (float)sourceWidth);
        nPercentH = ((float)Height / (float)sourceHeight);
        if (nPercentH < nPercentW)
        {
            nPercent = nPercentH;
        }
        else
        {
            nPercent = nPercentW;
        }

        int destWidth = (int)(sourceWidth * nPercent);
        int destHeight = (int)(sourceHeight * nPercent);

        Bitmap bmPhoto = new Bitmap(destWidth, destHeight, PixelFormat.Format24bppRgb);

        bmPhoto.SetResolution(imgPhoto.HorizontalResolution, imgPhoto.VerticalResolution);

        Graphics grPhoto = Graphics.FromImage(bmPhoto);
        grPhoto.DrawImage(imgPhoto,
                new Rectangle(X, Y, destWidth, destHeight),
                new Rectangle(X, Y, sourceWidth, sourceHeight),
                GraphicsUnit.Pixel);
        grPhoto.Dispose();
        bmPhoto.Save(targetPath);
       
    }
