从 C# 中的 HybridDictionary 中删除所有条目


要从 HybridDictionary 中删除所有条目,代码如下 −

示例

 实战演示

using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
   public static void Main(){
      HybridDictionary dict1 = new HybridDictionary();
      dict1.Add("A", "Books");
      dict1.Add("B", "Electronics");
      dict1.Add("C", "Smart Wearables");
      dict1.Add("D", "Pet Supplies");
      dict1.Add("E", "Clothing");
      dict1.Add("F", "Footwear");
      Console.WriteLine("HybridDictionary1 elements...");
      foreach(DictionaryEntry d in dict1){
         Console.WriteLine(d.Key + " " + d.Value);
      }
      Console.WriteLine("Count of Key/value pairs in Dictionary1 = "+dict1.Count);
      HybridDictionary dict2 = new HybridDictionary();
      dict2.Add("1", "One");
      dict2.Add("2", "Two");
      dict2.Add("3", "Three");
      dict2.Add("4", "Four");
      dict2.Add("5", "Five");
      dict2.Add("6", "Six");
      Console.WriteLine("
HybridDictionary2 elements...");       foreach(DictionaryEntry d in dict2){          Console.WriteLine(d.Key + " " + d.Value);       }       Console.WriteLine("Count of Key/value pairs in Dictionary2 = "+dict1.Count);       dict2.Clear();       Console.WriteLine("Count of Key/value pairs in Dictionary2 (Updated) = "+dict2.Count);    } }

输出

这将生成以下输出 −

HybridDictionary1 elements...
A Books
B Electronics
C Smart Wearables
D Pet Supplies
E Clothing
F Footwear
Count of Key/value pairs in Dictionary1 = 6

HybridDictionary2 elements...
1 One
2 Two
3 Three
4 Four
5 Five
6 Six
Count of Key/value pairs in Dictionary2 = 6
Count of Key/value pairs in Dictionary2 (Updated) = 0

示例

我们来看另一个示例 −

 实战演示

using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
   public static void Main(){
      HybridDictionary dict = new HybridDictionary();
      dict.Add("One", "Accessories");
      dict.Add("Two", "Pet Supplies");
      Console.WriteLine("HybridDictionary elements...");
      foreach(DictionaryEntry d in dict){
         Console.WriteLine(d.Key + " " + d.Value);
      }
      Console.WriteLine("Count of Key/value pairs in Dictionary = "+dict.Count);
   }
}

输出

这将生成以下输出 −

HybridDictionary elements...
One Accessories
Two Pet Supplies
Count of Key/value pairs in Dictionary = 2
