要从SortedSet中删除与谓词匹配的元素,代码如下-
using System; using System.Collections.Generic; public class Demo { private static bool demo(int i) { return ((i % 10) == 0); } public static void Main(String[] args) { SortedSet<int> set1 = new SortedSet<int>(); set1.Add(200); set1.Add(215); set1.Add(310); set1.Add(500); set1.Add(600); Console.WriteLine("SortedSet elements..."); foreach (int i in set1) { Console.WriteLine(i); } Console.WriteLine(" "); set1.RemoveWhere(demo); Console.WriteLine("SortedSet after removing some elements..."); foreach (int i in set1) { Console.WriteLine(i); } } }
输出结果
这将产生以下输出-
SortedSet elements... 200 215 310 500 600 SortedSet after removing some elements... 215
让我们看另一个例子-
using System; using System.Collections.Generic; public class Demo { private static bool demo(int i) { return (i == 500); } public static void Main(String[] args) { SortedSet<int> set1 = new SortedSet<int>(); set1.Add(200); set1.Add(215); set1.Add(310); set1.Add(500); set1.Add(600); Console.WriteLine("SortedSet elements..."); foreach (int i in set1) { Console.WriteLine(i); } Console.WriteLine(" "); set1.RemoveWhere(demo); Console.WriteLine("SortedSet after removing an element..."); foreach (int i in set1) { Console.WriteLine(i); } } }
输出结果
这将产生以下输出-
SortedSet elements... 200 215 310 500 600 SortedSet after removing an element... 200 215 310 600
