converting from vb to c#

Question

User898048251 posted

I have a piece of code in VB that I want to use to resize images.  I think I have successfully converted most of it to C#, but I am not sure about this bit :

Function ThumbnailCallback() as Boolean
    Return False
  End Function

Here is the bit of the code that is calling it :

Response.ContentType = "image/gif"
    If imageHeight > 0 and imageWidth > 0 then
      Dim dummyCallBack as System.Drawing.Image.GetThumbNailImageAbort
      dummyCallBack = New _
         System.Drawing.Image.GetThumbnailImageAbort(AddressOf ThumbnailCallback)

      Dim thumbNailImg as System.Drawing.Image
      thumbNailImg = fullSizeImg.GetThumbnailImage(imageWidth, imageHeight, _
                                                   dummyCallBack, IntPtr.Zero)

      thumbNailImg.Save(Response.OutputStream, ImageFormat.Gif) 

Can anybody help?
