在C#中获取SortedList对象中指定键的索引
要获取SortedList对象中指定键的索引，代码如下-
示例
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"));
}
}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
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 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"));
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 SortedList2 elements... A Accessories B Books C Smart Wearable Tech D Home Appliances Index at key B = 1
