difference between array and collection in .net

answer:

1) use an array when the number of elements that need to be inserted into the array is known at compile time and it remains fixed throughout the execution of the program. You use a collection when you do not know how many elements you will need to store. So basically a collection can grow in size dynamically. The data structure used to implement the collection depends on the collection type. e.g. for a Arraylist a doubly linked list may be used.

2) You can store elements of similar type only in an array. Unless ofcourse you declare an array of type 'Object'. In a collection you can store any type of elements provided they are all objects. You can store basic data types in an array. You can only store objects in a collection.
