System_CAPS_pubmethodWhere<T>(Func<T, Boolean>)

Overloaded. Filters a sequence of values based on a predicate.(Defined by Enumerable.)

System_CAPS_pubmethodZip<T, TSecond, TResult>(IEnumerable<TSecond>, Func<T, TSecond, TResult>)

Applies a specified function to the corresponding elements of two sequences, producing a sequence of the results.(Defined by Enumerable.)

A SortedSet<T> object maintains a sorted order without affecting performance as elements are inserted and deleted. Duplicate elements are not allowed. Changing the sort values of existing items is not supported and may lead to unexpected behavior.

For a thread safe alternative to SortedSet<T>, see ImmutableSortedSet<T>

The following example demonstrates a SortedSet<T> class that is created with the constructor that takes an IComparer<T> as a parameter. This comparer (ByFileExtension) is used to sort a list of file names by their extensions.

This example demonstrates how to create a sorted set of media file names, remove unwanted elements, view a range of elements, and compare the set with another sorted set.
