Copies the elements of the ListT to a new array.
Assembly: mscorlib (in mscorlib.dll)
Examples
The following code example demonstrates the ToArray method and other methods of the ListT class that act on ranges. At the end of the code example, the GetRange method is used to get three items from the list, beginning with index location 2. The ToArray method is called on the resulting ListT, creating an array of three elements. The elements of the array are displayed.
