Search in a SortedList object in C#
To search in a SortedList object, the code is as follows −
Example
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("Three")); Console.WriteLine("The SortedList object has a fixed size? = "+list.IsFixedSize); Console.WriteLine("Does the SortedList object contains key 10? = "+list.ContainsKey("10")); } }
Output
This will produce the following output −
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 The SortedList object has a fixed size? = False Does the SortedList object contains key 10? = False
Example
Let us see another example −
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); Console.WriteLine("
Enumerator to iterate through the SortedList..."); IDictionaryEnumerator demoEnum = sortedList.GetEnumerator(); while (demoEnum.MoveNext()) Console.WriteLine("Key = " + demoEnum.Key + ", Value = "+ demoEnum.Value); Console.WriteLine("Does the SortedList object contains key M? = "+sortedList.ContainsKey("M")); Console.WriteLine("Does the SortedList object contains key H? = "+sortedList.ContainsKey("H")); } }
Output
This will produce the following output −
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 = 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 Does the SortedList object contains key M? = False Does the SortedList object contains key H? = True
