C＃| Dictionary.Values属性

此属性用于获取包含Dictionary 中的值的集合。

句法：

public System.Collections.Generic.Dictionary.KeyCollection Values{ get; }

返回值：该属性返回一个包含Dictionary中的Values的集合。

下面的程序说明了Dictionary .Values属性的用法：

范例1：

// C# code to get the Values
// in the Dictionary
using System;
using System.Collections.Generic;
  
class GFG {
  
    // Driver code
    public static void Main()
    {
  
        // Create a new dictionary
        // of strings, with string keys.
        Dictionary myDict = 
           new Dictionary();
  
        // 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);
  
        // To get the values alone,
        // use the Values property.
        Dictionary.ValueCollection valueColl = 
                                                myDict.Values;
  
        // The elements of the ValueCollection
        // are strongly typed with the type 
        // that was specified for dictionary values.
        foreach(string s in valueColl)
        {
            Console.WriteLine("Value = {0}", s);
        }
    }
}

输出：

Total key/value pairs in myDict are : 6
Value = Canberra
Value = Brussels
Value = Amsterdam
Value = Beijing
Value = Moscow
Value = New Delhi

范例2：

// C# code to get the values
// in the Dictionary
using System;
using System.Collections.Generic;
  
class GFG {
  
    // Driver code
    public static void Main()
    {
  
        // Create a new dictionary of
        // strings, with string keys.
        Dictionary myDict = 
           new Dictionary();
  
        // 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);
  
        // To get the values alone, 
        // use the Values property.
        Dictionary.ValueCollection valueColl =  
                                           myDict.Values;
  
        // The elements of the ValueCollection
        // are strongly typed with the type 
        // that was specified for dictionary values.
        foreach(int s in valueColl)
        {
            Console.WriteLine("Values = {0}", s);
        }
    }
}

输出：

Total key/value pairs in myDict are : 4
Values = 8
Values = 4
Values = 7
Values = 7
