要将HybridDictionary条目复制到数组实例,代码如下-
using System; using System.Collections; using System.Collections.Specialized; public class Demo { public static void Main(){ HybridDictionary dict = new HybridDictionary(); dict.Add("1", "SUV"); dict.Add("2", "AUV"); dict.Add("3", "Utility Vehicle"); dict.Add("4", "MUV"); dict.Add("5", "Compact Car"); dict.Add("6", "Convertible"); Console.WriteLine("HybridDictionary Key and Value pairs..."); foreach(DictionaryEntry entry in dict){ Console.WriteLine("{0} and {1} ", entry.Key, entry.Value); } DictionaryEntry[] dictArr = new DictionaryEntry[10]; Console.WriteLine("\nCopied to Array Instance..."); dict.CopyTo(dictArr, 2); for (int i = 0; i < dictArr.Length; i++) Console.WriteLine("Key = "+dictArr[i].Key + ", Value = " + dictArr[i].Value); } }
输出结果
这将产生以下输出-
HybridDictionary Key and Value pairs... 1 and SUV 2 and AUV 3 and Utility Vehicle 4 and MUV 5 and Compact Car 6 and Convertible Copied to Array Instance... Key = , Value = Key = , Value = Key = 1, Value = SUV Key = 2, Value = AUV Key = 3, Value = Utility Vehicle Key = 4, Value = MUV Key = 5, Value = Compact Car Key = 6, Value = Convertible Key = , Value = Key = , Value =
现在让我们来看另一个示例-
using System; using System.Collections; using System.Collections.Specialized; public class Demo { public static void Main(){ HybridDictionary dict = new HybridDictionary(10); dict.Add("1", "SUV"); dict.Add("2", "AUV"); dict.Add("3", "Utility Vehicle"); dict.Add("4", "MUV"); Console.WriteLine("HybridDictionary Key and Value pairs..."); foreach(DictionaryEntry entry in dict){ Console.WriteLine("{0} and {1} ", entry.Key, entry.Value); } DictionaryEntry[] dictArr = new DictionaryEntry[10]; Console.WriteLine("\nCopied to Array Instance..."); dict.CopyTo(dictArr, 0); for (int i = 0; i < dictArr.Length; i++) Console.WriteLine("Key = "+dictArr[i].Key + ", Value = " + dictArr[i].Value); } }
输出结果
这将产生以下输出-
HybridDictionary Key and Value pairs... 1 and SUV 2 and AUV 3 and Utility Vehicle 4 and MUV Copied to Array Instance... Key = 1, Value = SUV Key = 2, Value = AUV Key = 3, Value = Utility Vehicle Key = 4, Value = MUV Key = , Value = Key = , Value = Key = , Value = Key = , Value = Key = , Value = Key = , Value =
