C# | Check if the StringCollection is read-only

C# | Check if StringCollection is synchronized (thread safe)

Last Updated : 01 Feb, 2019

StringCollection class is a new addition to the .NET Framework class library that represents a collection of strings. StringCollection class is defined in the System.Collections.Specialized namespace. StringCollection.IsSynchronized property is used to get a value indicating whether access to the StringCollection is synchronized (thread safe) or not. Syntax:

public bool IsSynchronized { get; }

Return Value: This property always returns false. Note: Retrieving the value of this property is an O(1) operation. Example:

CSHARP

// C# code to check if StringCollection
// is synchronized (thread safe)
using System;
using System.Collections;
using System.Collections.Specialized;

class GFG {

    // Driver code
    public static void Main()
    {

        // creating a StringCollection named myCol
        StringCollection myCol = new StringCollection();

        // creating a string array named myArr
        String[] myArr = new String[] { "A", "B", "C", "D", "E" };

        // Copying the elements of a string
        // array to the end of the StringCollection.
        myCol.AddRange(myArr);

        // checking if StringCollection is
        // synchronized (thread safe)
        Console.WriteLine(myCol.IsSynchronized);
    }
}

Output:

False
