C# |字典。价值属性
原文:https://www . geesforgeks . org/c-sharp-dictionary-values-property/
该属性用于获取包含字典中值的集合。
语法:
公共系统。集合。类属。词典。KeyCollection 值{ get}
返回值:该属性返回包含字典中值的集合。
以下是说明使用字典< TKey，TValue >的程序。值属性:
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<string, string> myDict =
new Dictionary<string, string>();
// 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<string, string>.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);
}
}
}
Output:
Total key/value pairs in myDict are : 6
Value = Canberra
Value = Brussels
Value = Amsterdam
Value = Beijing
Value = Moscow
Value = New Delhi
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<int, int> myDict =
new Dictionary<int, int>();
// 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<int, int>.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);
}
}
}
Output:
Total key/value pairs in myDict are : 4
Values = 8
Values = 4
Values = 7
Values = 7
