Typecast an ArrayList to Struct?

Question

Hi I have a query regarding the struct. 1) Can a method be created in a class with a return type struct? But my return type in the method should be a ArrayList? Please find the below sample code; Code Snippet: The below code is giving me an error. public Color GetRecentColor() { if (colorCollection.Count > 0) { return (Color)colorCollection[colorCollection.Count - 1]; } return null; } In the above code Color is a struct and colorCollection is an ArrayList. Is there a solution to typecast a struct to ArrayList? Thanks in advance Mayur M

Yes the return type of a method can be a struct such as System.Drawing.Color. You don't say what the error is but I suspect it's nothing to do with the ArrayList but is this line instead: return null; Unless it's declared as a nullable type a struct instance always contains some sort of a value and can never be null. So you need to substitute an actual color there. Try: return Color.Black; or some other default color that you'd use if your collection was empty.
