要将指定的键和值添加到ListDictionary中,代码如下-
using System; using System.Collections; using System.Collections.Specialized; public class Demo { public static void Main(){ ListDictionary dict = new ListDictionary(); dict.Add("1", "One"); dict.Add("2", "Two"); dict.Add("3", "Three"); dict.Add("4", "Four"); dict.Add("5", "Five"); Console.WriteLine("ListDictionary key-value pairs..."); IDictionaryEnumerator demoEnum = dict.GetEnumerator(); while (demoEnum.MoveNext()) Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); } }
输出结果
这将产生以下输出-
ListDictionary key-value pairs... Key = 1, Value = One Key = 2, Value = Two Key = 3, Value = Three Key = 4, Value = Four Key = 5, Value = Five
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(){ ListDictionary listDict = new ListDictionary(); listDict.Add("1", 100); listDict.Add("2", 200); listDict.Add("3", 300); listDict.Add("4", 400); listDict.Add("5", 500); listDict.Add("6", 600); listDict.Add("7", 700); listDict.Add("8", 800); listDict.Add("9", 900); listDict.Add("10", 1000); ICollection col = listDict.Keys; Console.WriteLine("Display all the keys..."); foreach(String s in col){ Console.WriteLine(s); } } }
输出结果
这将产生以下输出-
Display all the keys... 1 2 3 4 5 6 7 8 9 10
