要创建SortedList对象的浅表副本,代码如下-
using System; using System.Collections; public class Demo { public static void Main(String[] args){ SortedList list = new SortedList(); list.Add("A", "Jacob"); list.Add("B", "Sam"); list.Add("C", "Tom"); list.Add("D", "John"); list.Add("E", "Tim"); list.Add("F", "Mark"); list.Add("G", "Gary"); list.Add("H", "Nathan"); list.Add("I", "Shaun"); list.Add("J", "David"); Console.WriteLine("SortedList elements..."); foreach(DictionaryEntry d in list){ Console.WriteLine(d.Key + " " + d.Value); } ICollection col1 = list.Values; Console.WriteLine("\nValues..."); foreach(string s in col1) Console.WriteLine(s); ICollection col2 = list.Keys; Console.WriteLine("\nKeys..."); foreach(string s in col2) Console.WriteLine(s); SortedList list2 = (SortedList)list.Clone(); Console.WriteLine("\nResultant SortedList...cloned from above list"); foreach(DictionaryEntry d in list){ Console.WriteLine(d.Key + " " + d.Value); } } }
输出结果
这将产生以下输出-
SortedList elements... A Jacob B Sam C Tom D John E Tim F Mark G Gary H Nathan I Shaun J David Values... Jacob Sam Tom John Tim Mark Gary Nathan Shaun David Keys... A B C D E F G H I J Resultant SortedList...cloned from above list A Jacob B Sam C Tom D John E Tim F Mark G Gary H Nathan I Shaun J David
现在让我们来看另一个示例-
using System; using System.Collections; public class Demo { public static void Main(String[] args){ SortedList list = new SortedList(); list.Add("One", "IT"); list.Add("Two ", "Operations"); list.Add("Three", "Marketing"); list.Add("Four", "Purchase"); list.Add("Five", "Sales"); list.Add("Six", "Finance"); Console.WriteLine("SortedList elements..."); foreach(DictionaryEntry d in list){ Console.WriteLine(d.Key + " " + d.Value); } Console.WriteLine("\nList of values...SortedList"); IList col = list.GetValueList(); foreach(string res in col) { Console.WriteLine(res); } Console.WriteLine("\nSortedList is read-only? = "+list.IsReadOnly); SortedList list2 = (SortedList)list.Clone(); Console.WriteLine("\nResultant SortedList...cloned from above list"); foreach(DictionaryEntry d in list){ Console.WriteLine(d.Key + " " + d.Value); } } }
输出结果
这将产生以下输出-
SortedList elements... Five Sales Four Purchase One IT Six Finance Three Marketing Two Operations List of values...SortedList Sales Purchase IT Finance Marketing Operations SortedList is read-only? = False Resultant SortedList...cloned from above list Five Sales Four Purchase One IT Six Finance Three Marketing Two Operations
