C# ICollection.IsSynchronized Property with Examples

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.

IsSynchronized: False
