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("
Key/value pairs...");
foreach(KeyValuePair<string, string> res in dict){
Console.WriteLine("Key = {0}, Value = {1}", res.Key, res.Value);
}
Console.Write("
All the values..
");
Dictionary<string, string>.ValueCollection allValues=
dict.Values;
foreach(string str in allValues){
Console.WriteLine("Value = {0}", str);
}
}
}
输出
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
现在让我们看另一个实现 Dictionary.Values 属性的例子 −
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("
Key/value pairs...");
foreach(KeyValuePair<int, string> res in dict){
Console.WriteLine("Key = {0}, Value = {1}", res.Key, res.Value);
}
Console.Write("
All the values..
");
Dictionary<int, string>.ValueCollection allValues= dict.Values;
foreach(string str in allValues){
Console.WriteLine("Value = {0}", str);
}
}
}
输出
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
