List(T) Constructor (IEnumerable(T))
Initializes a new instance of the List(T) class that contains elements copied from the specified collection and has sufficient capacity to accommodate the number of elements copied.
Assemblies: mscorlib (in mscorlib.dll)
System.Collections (in System.Collections.dll)
collection is a null reference (Nothing in Visual Basic).
The elements are copied onto the List(T) in the same order they are read by the enumerator of the collection.
This constructor is an O(n) operation, where n is the number of elements in collection.
The following example demonstrates the List(T) constructor and various methods of the List(T) class that act on ranges. An array of strings is created and passed to the constructor, populating the list with the elements of the array. The Capacity property is then displayed, to show that the initial capacity is exactly what is required to hold the input elements.
