C# 中的 SortedDictionary.Values 属性
C# 中的 SortedDictionary.Value 属性用于获取集合,其中包含 SortedDictionary<TKey, TValue> 中的值。
语法
语法如下 −
public System.Collections.Generic.SortedDictionary<TKey,TValue>.ValueCollection Values { get; }
示例
下面来看一个示例 −
using System; using System.Collections; using System.Collections.Generic; public class Demo { public static void Main(){ SortedDictionary<int, string>sortedDict = new SortedDictionary<int, string>(); sortedDict.Add(1, "Ultrabook"); sortedDict.Add(2, "Alienware"); sortedDict.Add(3, "Notebook"); sortedDict.Add(4, "Connector"); sortedDict.Add(5, "Flash Drive"); sortedDict.Add(6, "SSD"); sortedDict.Add(7, "HDD"); sortedDict.Add(8, "Earphone"); Console.WriteLine("SortedDictionary key-value pairs..."); IDictionaryEnumerator demoEnum = sortedDict.GetEnumerator(); while (demoEnum.MoveNext()) Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); Console.WriteLine("
Key 7 removed from SortedDictionary? = "+sortedDict.Remove(7)); Console.WriteLine("
SortedDictionary key-value pairs...UPDATED"); demoEnum = sortedDict.GetEnumerator(); while (demoEnum.MoveNext()) Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); SortedDictionary<int, string>.KeyCollection keyList = sortedDict.Keys; Console.WriteLine("
Keys...list"); foreach( int i in keyList ){ Console.WriteLine(i); } SortedDictionary<int, string>.ValueCollection valList = sortedDict.Values; Console.WriteLine("
Values...list"); foreach( string s in valList ){ Console.WriteLine(s); } } }
输出
将生成以下输出 −
SortedDictionary key-value pairs... Key = 1, Value = Ultrabook Key = 2, Value = Alienware Key = 3, Value = Notebook Key = 4, Value = Connector Key = 5, Value = Flash Drive Key = 6, Value = SSD Key = 7, Value = HDD Key = 8, Value = Earphone Key 7 removed from SortedDictionary? = True SortedDictionary key-value pairs...UPDATED Key = 1, Value = Ultrabook Key = 2, Value = Alienware Key = 3, Value = Notebook Key = 4, Value = Connector Key = 5, Value = Flash Drive Key = 6, Value = SSD Key = 8, Value = Earphone Keys...list 1 2 3 4 5 6 8 Values...list Ultrabook Alienware Notebook Connector Flash Drive SSD Earphone
示例
下面再来看另一个示例 −
using System; using System.Collections; using System.Collections.Generic; public class Demo { public static void Main(){ SortedDictionary<int, string> sortedDict = new SortedDictionary<int, string>(); sortedDict.Add(1, "SUV"); sortedDict.Add(2, "MUV"); sortedDict.Add(3, "Hatchback"); sortedDict.Add(4, "AUV"); sortedDict.Add(5, "Covertible"); sortedDict.Add(6, "Crossover"); sortedDict.Add(7, "Utility Vehicle"); Console.WriteLine("SortedDictionary key-value pairs..."); IDictionaryEnumerator demoEnum = sortedDict.GetEnumerator(); while (demoEnum.MoveNext()) Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); Console.WriteLine("
Key 2 removed from SortedDictionary? = "+sortedDict.Remove(2)); Console.WriteLine("
SortedDictionary key-value pairs...UPDATED"); demoEnum = sortedDict.GetEnumerator(); while (demoEnum.MoveNext()) Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); SortedDictionary<int, string>.KeyCollection keyList = sortedDict.Keys; Console.WriteLine("
Keys...list"); foreach( int i in keyList ){ Console.WriteLine(i); } SortedDictionary<int, string>.ValueCollection valList = sortedDict.Values; Console.WriteLine("
Values...list"); foreach( string s in valList ){ Console.WriteLine(s); } } }
输出
将生成以下输出 −
SortedDictionary key-value pairs... Key = 1, Value = SUV Key = 2, Value = MUV Key = 3, Value = Hatchback Key = 4, Value = AUV Key = 5, Value = Covertible Key = 6, Value = Crossover Key = 7, Value = Utility Vehicle Key 2 removed from SortedDictionary? = True SortedDictionary key-value pairs...UPDATED Key = 1, Value = SUV Key = 3, Value = Hatchback Key = 4, Value = AUV Key = 5, Value = Covertible Key = 6, Value = Crossover Key = 7, Value = Utility Vehicle Keys...list 1 3 4 5 6 7 Values...list SUV Hatchback AUV Covertible Crossover Utility Vehicle
