C#中的Dictionary.Values属性
C#中的Dictionary.Values属性用于获取Dictionary中的所有值。
语法
以下是语法-
public System.Collections.Generic.Dictionary<TKey, TValue>.KeyCollection Values{ get; }示例
现在让我们看一个实现Dictionary.Values属性的示例-
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(){
Dictionary<string, string> dict = new Dictionary<string, string>();
dict.Add("One", "Kagido");
dict.Add("Two", "Ngidi");
dict.Add("Three", "Devillers");
dict.Add("Four", "Smith");
dict.Add("Five", "Warner");
Console.WriteLine("Count of elements = "+dict.Count);
Console.WriteLine("\nKey/value pairs...");
foreach(KeyValuePair<string, string> res in dict){
Console.WriteLine("Key = {0}, Value = {1}", res.Key, res.Value);
}
Console.Write("\nAll the values..\n");
Dictionary<string, string>.ValueCollection allValues=
dict.Values;
foreach(string str in allValues){
Console.WriteLine("Value = {0}", str);
}
}
}输出结果
这将产生以下输出-
Count of elements = 5 Key/value pairs... Key = One, Value = Kagido Key = Two, Value = Ngidi Key = Three, Value = Devillers Key = Four, Value = Smith Key = Five, Value = Warner All the values.. Value = Kagido Value = Ngidi Value = Devillers Value = Smith Value = Warner
示例
现在让我们来看另一个实现Dictionary.Values属性的示例-
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(){
Dictionary<int, string> dict = new Dictionary<int, string>();
dict.Add(1, "Kagido");
dict.Add(2, "Ngidi");
dict.Add(3, "Devillers");
Console.WriteLine("Count of elements = "+dict.Count);
Console.WriteLine("\nKey/value pairs...");
foreach(KeyValuePair<int, string> res in dict){
Console.WriteLine("Key = {0}, Value = {1}", res.Key, res.Value);
}
Console.Write("\nAll the values..\n");
Dictionary<int, string>.ValueCollection allValues= dict.Values;
foreach(string str in allValues){
Console.WriteLine("Value = {0}", str);
}
}
}输出结果
这将产生以下输出-
Count of elements = 3 Key/value pairs... Key = 1, Value = Kagido Key = 2, Value = Ngidi Key = 3, Value = Devillers All the values.. Value = Kagido Value = Ngidi Value = Devillers
