1.Arrays are built-in data structures in .NET, where as ArrayList must be imported from the .NET Framework library.
2.Array is a primitive data structure, which stores the values in an indexed format, where as an ArrayList is more like a vector, which can be resized. ArrayList is a Collection and stores all data as Objects.
3.Arrays are not always the best structures to use if the size of the data is likely to change. Arrays would give you the best results when you are working with strictly numeric values. Arrays are also helpful when you need direct access to far-away elements in your data set.
4.ArrayLists are more useful when dealing with non-numeric data.
Arrays are faster for calculation, where as ArrayLists are faster for inserting elements.
