从 C# 中的 SortedSet 中移除指定的项
要从 SortedSet 中移除指定的项,代码如下 −
示例
using System; using System.Collections.Generic; public class Demo { public static void Main(){ SortedSet<string> set1 = new SortedSet<string>(); set1.Add("AB"); set1.Add("BC"); set1.Add("CD"); set1.Add("EF"); Console.WriteLine("Elements in SortedSet1..."); foreach (string res in set1){ Console.WriteLine(res); } SortedSet<string> set2 = new SortedSet<string>(); set2.Add("BC"); set2.Add("CD"); set2.Add("DE"); set2.Add("EF"); set2.Add("AB"); set2.Add("HI"); set2.Add("JK"); Console.WriteLine("Elements in SortedSet2..."); foreach (string res in set2){ Console.WriteLine(res); } Console.WriteLine("Count of elements in SortedSet = " + set2.Count); set2.Remove("HI"); set2.Remove("JK"); Console.WriteLine("Count of elements in SortedSet (updated) = " + set2.Count); } }
输出
这将产生以下输出 −
Elements in SortedSet1... AB BC CD EF Elements in SortedSet2... AB BC CD DE EF HI JK Count of elements in SortedSet = 7 Count of elements in SortedSet (updated) = 5
示例
我们来看另一个示例 −
using System; using System.Collections.Generic; public class Demo { public static void Main(){ SortedSet<int> set1 = new SortedSet<int>(); set1.Add(100); set1.Add(200); set1.Add(300); set1.Add(400); Console.WriteLine("Elements in SortedSet..."); foreach (int res in set1){ Console.WriteLine(res); } Console.WriteLine("Count of elements in SortedSet = " + set1.Count); set1.Remove(100); Console.WriteLine("Count of elements in SortedSet (updated) = " + set1.Count); } }
输出
这将产生以下输出 −
Elements in SortedSet... 100 200 300 400 Count of elements in SortedSet = 4 Count of elements in SortedSet (updated) = 3
