HybridDictionary()创建一个空的区分大小写的HybridDictionary。

句法:

public HybridDictionary ();

下面给出了一些示例,以更好地理解实现:

范例1:

// C# code to create an empty
// case-sensitive HybridDictionary.
using System;
using System.Collections;
using System.Collections.Specialized;
  
class GFG {
  
    // Driver code
    public static void Main()
    {
  
        // Creating an empty case-sensitive
        // HybridDictionary named myDict
        HybridDictionary myDict = new HybridDictionary();
  
        // Adding key/value pairs in myDict
        myDict.Add("I", "first");
        myDict.Add("II", "second");
        myDict.Add("III", "third");
        myDict.Add("IV", "fourth");
        myDict.Add("V", "fifth");
  
        // Displaying the key/value pairs in myDict
        foreach(DictionaryEntry de in myDict)
            Console.WriteLine(de.Key + " " + de.Value);
    }
}

输出:

I first
II second
III third
IV fourth
V fifth

范例2:

// C# code to create an empty
// case-sensitive HybridDictionary.
using System;
using System.Collections;
using System.Collections.Specialized;
  
class GFG {
  
    // Driver code
    public static void Main()
    {
  
        // Creating an empty case-sensitive
        // HybridDictionary named myDict
        HybridDictionary myDict = new HybridDictionary();
  
        // Adding key/value pairs in myDict
        myDict.Add("A", "Apple");
  
        // To show that the HybridDictionary is
        // case-sensitive
        myDict.Add("a", "Air");
        myDict.Add("B", "Banana");
        myDict.Add("C", "Cat");
        myDict.Add("D", "Dog");
        myDict.Add("d", "Dolphine");
        myDict.Add("E", "Elephant");
        myDict.Add("F", "Fish");
  
        // Displaying the key/value pairs in myDict
        foreach(DictionaryEntry de in myDict)
            Console.WriteLine(de.Key + " " + de.Value);
    }
}

输出:

A Apple
a Air
B Banana
C Cat
D Dog
d Dolphine
E Elephant
F Fish

笔记:

  • 默认情况下,该集合区分大小写。
  • 比较器确定两个键是否相等。 HybridDictionary中的每个键都必须是唯一的。
  • 此构造函数是O(1)操作。
