ArrayList Constructor (ICollection)
Initializes a new instance of the ArrayList class that contains elements copied from the specified collection and that has the same initial capacity as the number of elements copied.
Assembly: mscorlib (in mscorlib.dll)
The capacity of a ArrayList is the number of elements that the ArrayList can hold. As elements are added to a ArrayList, the capacity is automatically increased as required by reallocating the internal array.
If the size of the collection can be estimated, specifying the initial capacity eliminates the need to perform a number of resizing operations while adding elements to the ArrayList.
This constructor is an O(n) operation, where n is the number of elements in c.
