要检查SortedSet是否是指定集合的超集,代码如下-
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(){
SortedSet<string> set1 = new SortedSet<string>();
set1.Add("CD");
set1.Add("CD");
set1.Add("CD");
set1.Add("CD");
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("SortedSet2 is a superset of SortedSet1? = "+set2.IsSupersetOf(set1));
}
}输出结果
这将产生以下输出-
Elements in SortedSet1... CD Elements in SortedSet2... AB BC CD DE EF HI JK SortedSet2 is a superset of SortedSet1? = True
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(10);
set1.Add(20);
set1.Add(30);
set1.Add(40);
set1.Add(50);
set1.Add(60);
Console.WriteLine("Elements in SortedSet1...");
foreach (int res in set1){
Console.WriteLine(res);
}
SortedSet<int> set2 = new SortedSet<int>();
set2.Add(10);
set2.Add(20);
set2.Add(30);
set2.Add(40);
set2.Add(50);
set2.Add(60);
set2.Add(70);
set2.Add(80);
set2.Add(90);
set2.Add(100);
Console.WriteLine("Elements in SortedSet2...");
foreach (int res in set2){
Console.WriteLine(res);
}
Console.WriteLine("SortedSet2 is a superset of SortedSet1? = "+set2.IsSupersetOf(set1));
}
}输出结果
这将产生以下输出-
Elements in SortedSet1... 10 20 30 40 50 60 Elements in SortedSet2... 10 20 30 40 50 60 70 80 90 100 SortedSet2 is a superset of SortedSet1? = True
