在C#中的SortedList对象的指定索引处获取键
要在SortedList对象的指定索引处获取密钥,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.Write("Index at key Five = "+list1.IndexOfKey("Five"));
Console.Write("\nKey at index 2 = "+list1.GetKey(2));
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("\n\nSortedList2 elements...");
foreach(DictionaryEntry d in list2) {
Console.WriteLine(d.Key + " " + d.Value);
}
Console.Write("Index at key B = "+list2.IndexOfKey("B"));
}
}
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
Index at key Five = 1
Key at index 2 = Four
SortedList2 elements...
A Accessories
B Books
C Smart Wearable Tech
D Home Appliances
Index at key B = 1
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", "Finance");
list.Add("Two", "Marketing");
list.Add("Three", "Sales");
list.Add("Four", "Purchase");
list.Add("Five", "Operations");
list.Add("Six", "IT");
Console.WriteLine("SortedList elements...");
foreach(DictionaryEntry d in list) {
Console.WriteLine(d.Key + " " + d.Value);
}
Console.WriteLine("\nIndex at key One = "+list.IndexOfKey("One"));
Console.Write("\nKey at index 5 = "+list.GetKey(5));
}
}
输出结果
这将产生以下输出-
SortedList elements...Five Operations
Four Purchase
One Finance
Six IT
Three Sales
Two Marketing
Index at key One = 2
Key at index 5 = Two
