C# | Check if StringDictionary is synchronized (thread safe) Last Updated : 11 Jul, 2025 Comments Improve Suggest changes Like Article Like Report StringDictionary.IsSynchronized property is used to get a value indicating whether access to the StringDictionary is synchronized (thread-safe). Syntax: public virtual bool IsSynchronized { get; } Return Value: This method returns True if access to the StringDictionary is synchronized (thread safe), otherwise it returns False. Example: CSHARP // C# code to check if StringDictionary // is synchronized (thread safe) using System; using System.Collections; using System.Collections.Specialized; class GFG { // Driver code public static void Main() { // Creating a StringDictionary named myDict StringDictionary myDict = new StringDictionary(); // Adding key and value into the StringDictionary myDict.Add("A", "Apple"); myDict.Add("B", "Banana"); myDict.Add("C", "Cat"); myDict.Add("D", "Dog"); myDict.Add("E", "Elephant"); // Checking if StringDictionary // is synchronized (thread safe) Console.WriteLine(myDict.IsSynchronized); } } Output: False Note: Retrieving the value of this property is an O(1) operation. A StringDictionary instance is not synchronized. Derived classes can provide a synchronized version of the StringDictionary using the SyncRoot property.
