在C#中获取SortedList对象的键列表
要获取SortedList对象的键列表，代码如下-
示例
using System;
using System.Collections;
public class Demo {
public static void Main(String[] args) {
SortedList list1 = new SortedList();
list1.Add("One", 1);
list1.Add("Two ", 2);
list1.Add("Three ", 3);
list1.Add("Four", 4);
list1.Add("Five", 5);
list1.Add("Six", 6);
list1.Add("Seven ", 7);
list1.Add("Eight ", 8);
list1.Add("Nine", 9);
list1.Add("Ten", 10);
Console.WriteLine("SortedList1 elements...");
foreach(DictionaryEntry d in list1) {
Console.WriteLine(d.Key + " " + d.Value);
}
Console.WriteLine("\nList of keys...SortedList1");
IList list = list1.GetKeyList();
foreach(string res in list)
Console.WriteLine(res);
SortedList list2 = new SortedList();
list2.Add("A", "Accessories");
list2.Add("B", "Books");
list2.Add("C", "Smart Wearable Tech");
list2.Add("D", "Home Appliances");
Console.WriteLine("\nSortedList2 elements...");
foreach(DictionaryEntry d in list2) {
Console.WriteLine(d.Key + " " + d.Value);
}
Console.WriteLine("\nList of keys...SortedList2");
list = list2.GetKeyList();
foreach(string res in list)
Console.WriteLine(res);
}
}输出结果
这将产生以下输出-
SortedList1 elements... Eight 8 Five 5 Four 4 Nine 9 One 1 Seven 7 Six 6 Ten 10 Three 3 Two 2 List of keys...SortedList1 Eight Five Four Nine One Seven Six Ten Three Two SortedList2 elements... A Accessories B Books C Smart Wearable Tech D Home Appliances List of keys...SortedList2 A B C D
示例
让我们看另一个例子-
using System;
using System.Collections;
public class Demo {
public static void Main(String[] args) {
SortedList list = new SortedList();
list.Add("One", 1);
list.Add("Two ", 2);
list.Add("Three ", 3);
list.Add("Four", 4);
list.Add("Five", 5);
Console.WriteLine("SortedList elements...");
foreach(DictionaryEntry d in list) {
Console.WriteLine(d.Key + " " + d.Value);
}
Console.WriteLine("\nList of keys...SortedList");
IList col = list.GetKeyList();
foreach(string res in col)
Console.WriteLine(res);
}
}输出结果
这将产生以下输出-
SortedList elements... Five 5 Four 4 One 1 Three 3 Two 2 List of keys...SortedList Five Four One Three Two
