在C#中的SortedList对象中获取指定值的索引
为了获得SortedList对象中指定值的索引,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 value 7 = "+list1.IndexOfValue(7));
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 value Books = "+list2.IndexOfValue("Books"));
}
}
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 value 7 = 5
SortedList2 elements...
A Accessories
B Books
C Smart Wearable Tech
D Home Appliances
Index at value Books = 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 value Marketing = "+list.IndexOfValue("Marketing"));
Console.WriteLine("Index at value Purchase = "+list.IndexOfValue("Purchase"));
Console.WriteLine("Index at value Sales = "+list.IndexOfValue("Sales"));
Console.WriteLine("Index at value IT = "+list.IndexOfValue("IT"));
Console.WriteLine("Index at value Operations = "+list.IndexOfValue("Operations"));
}
}
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 value Marketing = 5
Index at value Purchase = 1
Index at value Sales = 4
Index at value IT = 3
Index at value Operations = 0
