ArrayList represents an ordered collection of an object that can be indexed individually. It is basically an alternative to an array. It allows dynamic memory allocation, adding, searching and sorting items in the list. Example: In the below program, mylist is the ArrayList and we added 7 items to it which are the name of weekdays.

Then we are creating an object array obj1 and using ToArray method with mylist we will assign the Arraylist elements to the object array. Finally, using foreach loop you can print the required converted array. For conversion, you have to use ToArray Type method along with typeof keyword. And then you have to explicitly cast it to the specified type.

ToArray typeof string. There is another alternative for this line of code as shown in below example. Writing code in comment?
