示例

下面的示例演示SortedSet<T>使用IComparer<T>采用作为参数的构造函数创建的类。The following example demonstrates a SortedSet<T> class that is created with the constructor that takes an IComparer<T> as a parameter. 此比较器ByFileExtension()用于按文件扩展名对文件名列表进行排序。This comparer (ByFileExtension) is used to sort a list of file names by their extensions.

此示例演示如何创建一组排序的媒体文件名称、删除不需要的元素、查看某个范围内的元素,并将该集与其他排序集进行比较。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.
