检查 SortedList 对象是否在 C# 中包含特定值
若要检查 SortedList 对象是否包含特定值,代码如下 −
示例
using System; using System.Collections; public class Demo { public static void Main(){ SortedList list = new SortedList(); list.Add("1", "One"); list.Add("2", "Two"); list.Add("3", "Three"); list.Add("4", "Four"); list.Add("5", "Five"); list.Add("6", "Six"); list.Add("7", "Seven"); list.Add("8", "Eight"); Console.WriteLine("Key and Value of SortedList...."); foreach(DictionaryEntry k in list ) Console.WriteLine("Key: {0}, Value: {1}", k.Key , k.Value ); Console.WriteLine("Is the SortedList having the value? "+list.ContainsValue("Five")); } }
输出
这会产生以下输出 −
Key and Value of SortedList.... Key: 1, Value: One Key: 2, Value: Two Key: 3, Value: Three Key: 4, Value: Four Key: 5, Value: Five Key: 6, Value: Six Key: 7, Value: Seven Key: 8, Value: Eight Is the SortedList having the value? True
示例
我们来看看另一个示例 −
using System; using System.Collections; public class Demo { public static void Main(){ SortedList list = new SortedList(); list.Add("1", "One"); list.Add("2", "Two"); list.Add("3", "Three"); list.Add("4", "Four"); list.Add("5", "Five"); list.Add("6", "Six"); list.Add("7", "Seven"); list.Add("8", "Eight"); Console.WriteLine("Key and Value of SortedList...."); foreach(DictionaryEntry k in list ) Console.WriteLine("Key: {0}, Value: {1}", k.Key , k.Value ); Console.WriteLine("Is the SortedList having the value? "+list.ContainsValue("Tenth")); } }
输出
这会产生以下输出 −
Key and Value of SortedList.... Key: 1, Value: One Key: 2, Value: Two Key: 3, Value: Three Key: 4, Value: Four Key: 5, Value: Five Key: 6, Value: Six Key: 7, Value: Seven Key: 8, Value: Eight Is the SortedList having the value? False
