获取C#中SortedSet中的元素数
要获取SortedSet中的元素数量，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);
}
Console.WriteLine("Count of elements in SorteSet1 = "+set1.Count);
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);
}
Console.WriteLine("Count of elements in SorteSet2 = "+set2.Count);
}
}输出结果
这将产生以下输出-
Elements in SortedSet1... AB BC CD EF Count of elements in SorteSet1 = 4 Elements in SortedSet2 (Enumerator for SortedSet)... AB BC CD DE EF HI JK Count of elements in SorteSet2 = 7
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.Clear();
Console.WriteLine("Count of elements in SortedSet (updated) = " + set1.Count);
}
}输出结果
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) = 0
