C# ICollection.IsSynchronized Property with Examples

Last Updated : 18 Feb, 2022

ICollection is an interface that contains size, enumerations, and synchronization methods for all nongeneric collections. It is the base interface for classes in System.Collections namespace. IsSynchronized is also a property of the ICollection interface. This property in C# is defined under System.Collections namespace and a part of System.Runtime.dll assembly. It is used to check whether the access to the ICollection is thread-safe i.e, synchronized or not. It will return true if the access to the IsCollection is thread-safe. Otherwise, it will return false.

Syntax:

public bool IsSynchronized { get; }

Return type: The return type of this property is Boolean, i.e. either true or false. It will return true if the access to the IsCollection is thread-safe (or synchronized). Or it will return false when the access to the IsCollection is not thread-safe (or non-synchronized)

Example: In this example, we have initialized str with string literals. Then, we are passing it to the Display() function as a parameter. Display() method accepts it as an ICollection interface. Finally, we have used ICollection.IsSynchronized property on it.

C#

// C# program to demonstrate the working of 
// ICollection.IsSynchronized property 
using System; 
using System.Collections; 
  
class GFG { 
      
// Display function 
public static void Display(ICollection iCollection) 
{ 
      
    // Apply iCollection.IsSynchronized property  
    // on the ICollection interface 
    Console.WriteLine("IsSynchronized: {0}", 
                      iCollection.IsSynchronized); 
} 
  
// Driver code 
static public void Main() 
{ 
      
    // Initializing a string array 
    string[] str = { "Bhuwanesh", "Nainwal",  
                     "Harshit", "Nainwal" }; 
      
    // Calling display function  
    Display(str); 
    Console.ReadLine(); 
} 
}
