C# | SortedDictionary。价值属性
原文:https://www . geeksforgeeks . org/c-sharp-sorted dictionary-values-property/
此属性用于获取包含 SortedDictionary 中的值的集合。
语法:
public System.Collections.Generic.SortedDictionary<TKey,TValue>.ValueCollection Values { get; }
返回值:它返回一个包含 SortedDictionary 中的值的集合。
下面是说明上述属性使用的程序:
例 1:
// C# code to get the values
// in the SortedDictionary
using System;
using System.Collections.Generic;
class GFG {
// Driver code
public static void Main()
{
// Create a new SortedDictionary
// of strings, with string keys.
SortedDictionary<string, string> myDict =
new SortedDictionary<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.
SortedDictionary<string, string>.ValueCollection valColl =
myDict.Values;
// The elements of the ValueCollection
// are strongly typed with the type
// that was specified for dictionary
// values
foreach(string s in valColl)
{
Console.WriteLine("Value = {0}", s);
}
}
}
Output:
Total key/value pairs in myDict are : 6
Value = Canberra
Value = Brussels
Value = Beijing
Value = New Delhi
Value = Amsterdam
Value = Moscow
例 2:
// C# code to get the values
// in the SortedDictionary
using System;
using System.Collections.Generic;
class GFG {
// Driver code
public static void Main()
{
// Create a new SortedDictionary
// of ints, with int keys.
SortedDictionary<int, int> myDict =
new SortedDictionary<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.
SortedDictionary<int, int>.ValueCollection valColl =
myDict.Values;
// The elements of the ValueCollection
// are strongly typed with the type
// that was specified for dictionary
// values
foreach(int s in valColl)
{
Console.WriteLine("Value = {0}", s);
}
}
}
Output:
Total key/value pairs in myDict are : 4
Value = 7
Value = 4
Value = 7
Value = 8
