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
