Nina Braca Contributing Writer Instagram Twitter. precise control over the runtime type of the output array, and may, under certain circumstances, be used to save allocation costs. The behavior of this Invokes a transform function on each element of a generic sequence and returns the maximum resulting value. Returns elements from a sequence as long as a specified condition is true. That means a list element of a List object does not have to be boxed before the element can be used, and after about 500 list elements are created, the memory saved by not boxing list elements is greater than the memory used to generate the class implementation. Reverses the order of the elements in the specified range. To ensure thread safety, lock the collection during a read or write operation. the element, it is unchanged. Creates a shallow copy of the current Object. on what elements may be added. An element of the original list is set to "Coelophysis" using the Item[] property (the indexer in C#), and the contents of the read-only list are displayed again to demonstrate that it is just a wrapper for the original list. The element's index is used in the logic of the predicate function.
