要在SortedList中添加键/值对,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"); ICollection col1 = list.Values; Console.WriteLine("Values..."); foreach(string s in col1) Console.WriteLine(s); ICollection col2 = list.Keys; Console.WriteLine("\nKeys..."); foreach(string s in col2) Console.WriteLine(s); } }
这将产生以下输出-
Values... Jacob Sam Tom John Tim Mark Gary Nathan Shaun David Keys... A B C D E F G H I J
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 sortedList = new SortedList(); sortedList.Add("A", "1"); sortedList.Add("B", "2"); sortedList.Add("C", "3"); sortedList.Add("D", "4"); sortedList.Add("E", "5"); sortedList.Add("F", "6"); sortedList.Add("G", "7"); sortedList.Add("H", "8"); sortedList.Add("I", "9"); sortedList.Add("J", "10"); Console.WriteLine("SortedList elements..."); foreach(DictionaryEntry d in sortedList){ Console.WriteLine("Key = "+d.Key + ", Value = " + d.Value); } Console.WriteLine("Count of SortedList key-value pairs = "+sortedList.Count); sortedList.RemoveAt(3); Console.WriteLine("\nEnumerator to iterate through the SortedList..."); IDictionaryEnumerator demoEnum = sortedList.GetEnumerator(); while (demoEnum.MoveNext()) Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); Console.WriteLine("Count of SortedList key-value pairs (Updated) = "+sortedList.Count); } }
输出结果
这将产生以下输出-
SortedList elements... Key = A, Value = 1 Key = B, Value = 2 Key = C, Value = 3 Key = D, Value = 4 Key = E, Value = 5 Key = F, Value = 6 Key = G, Value = 7 Key = H, Value = 8 Key = I, Value = 9 Key = J, Value = 10 Count of SortedList key-value pairs = 10 Enumerator to iterate through the SortedList... Key = A, Value = 1 Key = B, Value = 2 Key = C, Value = 3 Key = E, Value = 5 Key = F, Value = 6 Key = G, Value = 7 Key = H, Value = 8 Key = I, Value = 9 Key = J, Value = 10 Count of SortedList key-value pairs (Updated) = 9
