Title Body

Why am I getting an out of memory exception? So this dies in C# on the first time through: splitBitmaps.Add(neededImage.Clone(rectDimensions, neededImage.PixelFormat)); Where splitBitmaps is a List<BitMap> BUT this works in VB for at least 4 iterations: arlSplitBitmaps.Add(Image.Clone(rectDimensions, Image.PixelFormat)) Where arlSplitBitmaps is a simple array list. (And yes I've tried arraylist in c#) This is the fullsection: for (Int32 splitIndex = 0; splitIndex <= numberOfResultingImages - 1; splitIndex++) { Rectangle rectDimensions; if (splitIndex < numberOfResultingImages - 1) { rectDimensions = new Rectangle(splitImageWidth * splitIndex, 0, splitImageWidth, splitImageHeight); } else { rectDimensions = new Rectangle(splitImageWidth * splitIndex, 0, sourceImageWidth - (splitImageWidth * splitIndex), splitImageHeight); } splitBitmaps.Add(neededImage.Clone(rectDimensions, neededImage.PixelFormat)); } neededImage is a Bitmap by the way. I can't find any useful answers on the intarweb, especially not why it works just fine in VB. Update: I actually found a reason (sort of) for this working but forgot to post it. It has to do with converting the image to a bitmap instead of just trying to clone the raw image if I remember.
