Remove all entries from the ListDictionary in C#
To remove all entries from the ListDictionary, the code is as follows −
Example
using System; using System.Collections; using System.Collections.Specialized; public class Demo { public static void Main(){ ListDictionary dict1 = new ListDictionary(); dict1.Add("A", "Books"); dict1.Add("B", "Electronics"); dict1.Add("C", "Smart Wearables"); dict1.Add("D", "Pet Supplies"); dict1.Add("E", "Clothing"); dict1.Add("F", "Footwear"); Console.WriteLine("ListDictionary1 elements..."); foreach(DictionaryEntry d in dict1){ Console.WriteLine(d.Key + " " + d.Value); } ListDictionary dict2 = new ListDictionary(); dict2.Add("1", "One"); dict2.Add("2", "Two"); dict2.Add("3", "Three"); dict2.Add("4", "Four"); dict2.Add("5", "Five"); dict2.Add("6", "Six"); Console.WriteLine("
ListDictionary2 elements..."); foreach(DictionaryEntry d in dict2){ Console.WriteLine(d.Key + " " + d.Value); } Console.WriteLine("Count of key/value pairs in Dictionary 2 = "+dict2.Count); ListDictionary dict3 = new ListDictionary(); dict3 = dict2; Console.WriteLine("
Is ListDictionary3 equal to ListDictionary2? = "+(dict3.Equals(dict2))); dict3.Clear(); Console.WriteLine("Count of key/value pairs in Dictionary 3 = "+dict3.Count); } }
Output
This will produce the following output −
ListDictionary1 elements... A Books B Electronics C Smart Wearables D Pet Supplies E Clothing F Footwear ListDictionary2 elements... 1 One 2 Two 3 Three 4 Four 5 Five 6 Six Count of key/value pairs in Dictionary 2 = 6 Is ListDictionary3 equal to ListDictionary2? = True Count of key/value pairs in Dictionary 3 = 0
Example
Let us see another example −
using System; using System.Collections; using System.Collections.Specialized; public class Demo { public static void Main(){ ListDictionary dict1 = new ListDictionary(); dict1.Add("A", "Books"); dict1.Add("B", "Electronics"); dict1.Add("C", "Smart Wearables"); dict1.Add("D", "Pet Supplies"); dict1.Add("E", "Clothing"); dict1.Add("F", "Footwear"); Console.WriteLine("ListDictionary1 elements..."); foreach(DictionaryEntry d in dict1){ Console.WriteLine(d.Key + " " + d.Value); } Console.WriteLine("Count of key/value pairs in Dictionary 1 = "+dict1.Count); } }
Output
This will produce the following output −
ListDictionary1 elements... A Books B Electronics C Smart Wearables D Pet Supplies E Clothing F Footwear Count of key/value pairs in Dictionary 1 = 6
