C# 中的 SortedSet 类

The SortedSet class in C# represents a collection of objects that is maintained in sorted order.

Following are the properties of the SortedSet class −

以下是SortedSet类的一些方法：

Removes all elements from the set.

Determines whether the set contains a specific element.

Copies the complete SortedSet<T> to a compatible onedimensional array, starting at the beginning of the target array.

Copies the complete SortedSet<T> to a compatible onedimensional array, starting at the specified array index.

Copies a specified number of elements 从SortedSet<T>转换为兼容的一维数组 array, starting at the specified array index.

Returns an IEqualityComparer object that can be used to 创建一个包含个别集合的集合。

示例

现在让我们看一些示例 −

要检查 SortedSet 是否包含特定元素，代码如下 −

实时演示

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);
      }
      Console.WriteLine("Does the SortedSet1 contains the element DE? = "+set1.Contains("DE"));
      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));
   }
}

Output

This will produce the following output −

Elements in SortedSet1...
CD
Does the SortedSet1 contains the element DE? = False
Elements in SortedSet2...
AB
BC
CD
DE
EF
HI
JK
SortedSet2 is a superset of SortedSet1? = True

要获得一个遍历SortedSet的枚举器，代码如下 −

   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 (Enumerator for SortedSet)...");
      SortedSet<string>.Enumerator demoEnum = set2.GetEnumerator();
      while (demoEnum.MoveNext()) {
         string res = demoEnum.Current;
         Console.WriteLine(res);
      }
   }
}

Output

This will produce the following output −

Elements in SortedSet1...
AB
BC
CD
EF
Elements in SortedSet2 (Enumerator for SortedSet)...
AB
BC
CD
DE
EF
HI
JK
