将容量设置为C#中SortedList对象中元素的实际数量？
要将容量设置为SortedList对象中元素的实际数量，代码如下-
示例
using System;
using System.Collections;
public class Demo {
public static void Main(String[] args) {
SortedList sortedList = new SortedList();
sortedList.Add("A", "1");
sortedList.Add("B", "2");
sortedList.Add("C", "3");
sortedList.Add("D", "4");
sortedList.Add("E", "5");
sortedList.Add("F", "6");
sortedList.Add("G", "7");
sortedList.Add("H", "8");
sortedList.Add("I", "9");
sortedList.Add("J", "10");
Console.WriteLine("SortedList elements...");
foreach(DictionaryEntry d in sortedList) {
Console.WriteLine("Key = "+d.Key + ", Value = " + d.Value);
}
Console.WriteLine("\nEnumerator to iterate through the SortedList...");
IDictionaryEnumerator demoEnum = sortedList.GetEnumerator();
while (demoEnum.MoveNext())
Console.WriteLine("Key = " + demoEnum.Key + ", Value = "+ demoEnum.Value);
Console.WriteLine("Count of SortedList key-value pairs = "+sortedList.Count);
Console.WriteLine("Capacity of SortedList = "+sortedList.Capacity);
sortedList.TrimToSize();
Console.WriteLine("Capacity of SortedList (Updated) = "+sortedList.Capacity);
}
}输出结果
这将产生以下输出-
SortedList elements... Key = A, Value = 1 Key = B, Value = 2 Key = C, Value = 3 Key = D, Value = 4 Key = E, Value = 5 Key = F, Value = 6 Key = G, Value = 7 Key = H, Value = 8 Key = I, Value = 9 Key = J, Value = 10 Enumerator to iterate through the SortedList... Key = A, Value = 1 Key = B, Value = 2 Key = C, Value = 3 Key = D, Value = 4 Key = E, Value = 5 Key = F, Value = 6 Key = G, Value = 7 Key = H, Value = 8 Key = I, Value = 9 Key = J, Value = 10 Count of SortedList key-value pairs = 10 Capacity of SortedList = 16 Capacity of SortedList (Updated) = 10
示例
现在让我们来看另一个示例-
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);
Console.WriteLine("Capacity of SortedList1 = "+list1.Capacity);
list1.TrimToSize();
Console.WriteLine("Capacity of SortedList1 (Updated) = "+list1.Capacity);
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);
Console.WriteLine("Capacity of SortedList2 = "+list2.Capacity);
list2.TrimToSize();
Console.WriteLine("Capacity of SortedList2 (Updated) = "+list2.Capacity);
}
}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 Capacity of SortedList1 = 16 Capacity of SortedList1 (Updated) = 10 SortedList2 elements... A Accessories B Books C Smart Wearable Tech D Home Appliances List of keys...SortedList2 A B C D Capacity of SortedList2 = 16 Capacity of SortedList2 (Updated) = 4 L
