For example, in draw method I need an instance of Rectangle to be used. Like this:

Rectangle rect = new Rectangle(FrameSize * CurrentFrame, 0, FrameSize, FrameSize);

Or other way. Define temp rectangle data member, and then use it like this:

rect.X = FrameSize * CurrentFrame;
rect.Y = 0;
rect.Width = FrameSize;
rect.Height = FrameSize;

Which way is better? One thing confuses me is that many rectangles created frequently, but many code solutions use first approach, while second one should be careful about memory consumptions.

    Unless you have proved by careful measurement that reuse improves your performance you should create a new object every time.

    .NET handles object creation and GC very efficient, you should not worry about any performance hit here. The second solution needs more careful coding to make sure you don’t reuse objects in use somewhere else and you don’t have previous state lugging around. Further more you will have more objects aging into gen1 or gen2 in the GC.
