📅  最后修改于: 2021-05-29 21:45:18             🧑  作者: Mango

此属性用于获取SortedDictionary 包含的键/值对的数量。

句法:

public int Count { get; }

返回值:返回SortedDictionary中包含的键/值对的数量。

下面是说明上述财产的使用的程序:

范例1:

// C# code to count the number of
// key/value pairs in SortedDictionary
using System;
using System.Collections.Generic;
  
class GFG {
  
    // Driver code
    public static void Main()
    {
  
        // Create a new SortedDictionary of
        // int, with int keys.
        SortedDictionary myDict = 
           new SortedDictionary();
  
        // Adding key/value pairs in myDict
        myDict.Add(9, 8);
        myDict.Add(3, 4);
        myDict.Add(4, 7);
        myDict.Add(1, 7);
  
        // To get count of key/value pairs in myDict
        Console.WriteLine("Total key/value pairs "
              + "in myDict are : " + myDict.Count);
    }
}
输出:
Total key/value pairs in myDict are : 4

范例2:

// C# code to count the number of
// key/value pairs in  SortedDictionary
using System;
using System.Collections.Generic;
  
class GFG {
  
    // Driver code
    public static void Main()
    {
  
        // Create a new dictionary of
        // strings, with string keys.
        SortedDictionary myDict = 
          new SortedDictionary();
  
        // Adding key/value pairs in myDict
        myDict.Add("Australia", "Canberra");
        myDict.Add("Belgium", "Brussels");
        myDict.Add("Netherlands", "Amsterdam");
        myDict.Add("China", "Beijing");
        myDict.Add("Russia", "Moscow");
        myDict.Add("India", "New Delhi");
  
        // To get count of key/value pairs in myDict
        Console.WriteLine("Total key/value pairs "
              + "in myDict are : " + myDict.Count);
    }
}
输出:
Total key/value pairs in myDict are : 6
