要获取包含HybridDictionary中的键的ICollection,代码如下-
using System; using System.Collections.Specialized; public class Demo { public static void Main(){ HybridDictionary dict = new HybridDictionary(); dict.Add("One", "Katie"); dict.Add("Two", "Andy"); dict.Add("Three", "Gary"); dict.Add("Four", "Mark"); dict.Add("Five", "Marie"); dict.Add("Six", "Sam"); dict.Add("Seven", "Harry"); dict.Add("Eight", "Kevin"); dict.Add("Nine", "Ryan"); String[] strArr = new String[dict.Count]; dict.Keys.CopyTo(strArr, 0); for (int i = 0; i < dict.Count; i++) Console.WriteLine(strArr[i]); } }
输出结果
这将产生以下输出-
Eight Seven Four Three One Five Six Two Nine
让我们看另一个例子-
using System; using System.Collections.Specialized; public class Demo { public static void Main(){ HybridDictionary dict = new HybridDictionary(); dict.Add("1", "A"); dict.Add("2", "B"); dict.Add("3", "C"); dict.Add("4", "D"); dict.Add("5", "E"); dict.Add("6", "F"); String[] strArr = new String[dict.Count]; dict.Keys.CopyTo(strArr, 0); for (int i = 0; i < dict.Count; i++) Console.WriteLine(strArr[i]); } }
输出结果
这将产生以下输出-
1 2 3 4 5 6
