要从 SortedSet 中删除指定项，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
让我们看另一个例子 −
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
