Check if ListDictionary is synchronized in C#

To check if ListDictionary is synchronized, the code is as follows −

Example

 Live Demo

using System; using System.Collections; using System.Collections.Specialized; public class Demo {    public static void Main(){       ListDictionary dict = new ListDictionary();       dict.Add("1", "SUV");       dict.Add("2", "Sedan");       dict.Add("3", "Utility Vehicle");       dict.Add("4", "Compact Car");       dict.Add("5", "SUV");       dict.Add("6", "Sedan");       dict.Add("7", "Utility Vehicle");       dict.Add("8", "Compact Car");       dict.Add("9", "Crossover");       dict.Add("10", "Electric Car");       Console.WriteLine("ListDictionary elements...");       foreach(DictionaryEntry d in dict){          Console.WriteLine(d.Key + " " + d.Value);       }       Console.WriteLine("
Is the ListDictionary having fixed size? = "+dict.IsFixedSize);       Console.WriteLine("If ListDictionary read-only? = "+dict.IsReadOnly);       Console.WriteLine("Is ListDictionary synchronized = "+dict.IsSynchronized);       Console.WriteLine("The ListDictionary has the key K? = "+dict.Contains("K"));       Console.WriteLine("The ListDictionary has the key 9? = "+dict.Contains("9"));    } }

Output

This will produce the following output −

ListDictionary elements... 1 SUV 2 Sedan 3 Utility Vehicle 4 Compact Car 5 SUV 6 Sedan 7 Utility Vehicle 8 Compact Car 9 Crossover 10 Electric Car Is the ListDictionary having fixed size? = False If ListDictionary read-only? = False Is ListDictionary synchronized = False The ListDictionary has the key K? = False The ListDictionary has the key 9? = True

Example

Let us see another example −

 Live Demo

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 key-value pairs...");       IDictionaryEnumerator demoEnum = dict2.GetEnumerator();       while (demoEnum.MoveNext())          Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);       Console.WriteLine("Is the ListDictionary having fixed size? = "+dict2.IsFixedSize);       Console.WriteLine("If ListDictionary read-only? = "+dict2.IsReadOnly);       Console.WriteLine("Is ListDictionary synchronized = "+dict2.IsSynchronized);       Console.WriteLine("The ListDictionary has the key 5? = "+dict2.Contains("5"));    } }

Output

This will produce the following output −

ListDictionary1 elements... A Books B Electronics C Smart Wearables D Pet Supplies E Clothing F Footwear ListDictionary2 key-value pairs... Key = 1, Value = One Key = 2, Value = Two Key = 3, Value = Three Key = 4, Value = Four Key = 5, Value = Five Key = 6, Value = Six Is the ListDictionary having fixed size? = False If ListDictionary read-only? = False Is ListDictionary synchronized = False The ListDictionary has the key 5? = True
