I want to change the brightness and contrast of a bmp grayscale image.

I am converting .raw image into bmp and then displaying on image control in wpf. My UI is in WPF. I am also saving the bmp image in png or jpeg format. Now the challenge is correcting the bmp image using brightness and contrast. So is there any solution in C# or openCV or Aforge?

What I have tried:

public void DisplayImage16(string fileName)
       {

           try
           {

               BinaryReader br = new BinaryReader(File.Open(fileName, FileMode.Open));
               ushort pixShort;
               int i;
               long iTotalSize = br.BaseStream.Length;
               int iNumberOfPixels = (int)(iTotalSize / 2);

               // Get the dimensions of the image from the user
               ID = new ImageDimentions(iNumberOfPixels);
               if (ID.ShowDialog() == true)
               {
                   width = Convert.ToInt32(ID.tbWidth.Text);
                   height = Convert.ToInt32(ID.tbHeight.Text);
                   canvas.Width = width;
                   canvas.Height = height;
                   img.Width = width;
                   img.Height = height;
                   pix16 = new ushort[iNumberOfPixels];

                   for (i = 0; i < iNumberOfPixels; ++i)
                   {
                       pixShort = (ushort)(br.ReadUInt16());
                       pix16[i] = pixShort ;

                   }
                   br.Close();

                   int bitsPerPixel = 16;
                   stride = (width * bitsPerPixel + 7) / 8;

                   // Single step creation of the image
                   bmps = BitmapSource.Create(width, height, 96, 96, PixelFormats.Gray16, null,
                       pix16, stride);
                   img.Source = bmps;
                   btnSavejpg.IsEnabled = true;
                   btnSavePng.IsEnabled = true;
               }
               else
               {
                   br.Close();
               }

           }
           catch (Exception e)
           {
               MessageBox.Show(e.Message, "Error", MessageBoxButton.OK, MessageBoxImage.Error);

           }
       }
