要从 SortedSet 中删除符合谓词的元素，代码如下 −
示例
using System;
using System.Collections.Generic;
public class Demo {
private static bool demo(int i) {
return ((i % 10) == 0);
}
public static void Main(String[] args) {
SortedSet<int> set1 = new SortedSet<int>();
set1.Add(200);
set1.Add(215);
set1.Add(310);
set1.Add(500);
set1.Add(600);
Console.WriteLine("SortedSet elements...");
foreach (int i in set1) {
Console.WriteLine(i);
}
Console.WriteLine(" ");
set1.RemoveWhere(demo);
Console.WriteLine("SortedSet after removing some elements...");
foreach (int i in set1) {
Console.WriteLine(i);
}
}
}
输出
这将产生以下输出 −
SortedSet elements... 200 215 310 500 600 SortedSet after removing some elements... 215
示例
让我们看另一个例子 −
using System;
using System.Collections.Generic;
public class Demo {
private static bool demo(int i) {
return (i == 500);
}
public static void Main(String[] args) {
SortedSet<int> set1 = new SortedSet<int>();
set1.Add(200);
set1.Add(215);
set1.Add(310);
set1.Add(500);
set1.Add(600);
Console.WriteLine("SortedSet elements...");
foreach (int i in set1) {
Console.WriteLine(i);
}
Console.WriteLine(" ");
set1.RemoveWhere(demo);
Console.WriteLine("SortedSet after removing an element...");
foreach (int i in set1) {
Console.WriteLine(i);
}
}
}
输出
这将产生以下输出 −
SortedSet elements... 200 215 310 500 600 SortedSet after removing an element... 200 215 310 600
