HybridDictionary.IsSynchronized Property

Definition

Gets a value indicating whether the HybridDictionary is synchronized (thread safe).

public bool IsSynchronized { get; }

Property Value

This property always returns false.

Implements

Examples

The following code example shows how to lock the collection using the SyncRoot during the entire enumeration.

HybridDictionary myCollection = new HybridDictionary();
lock(myCollection.SyncRoot)
{
    foreach (object item in myCollection)
    {
        // Insert your code here.
    }
}

Retrieving the value of this property is an O(1) operation.

Remarks

HybridDictionary implements the IsSynchronized property because it is required by the System.Collections.ICollection interface.

Derived classes can provide a synchronized version of the HybridDictionary using the SyncRoot property.

Enumerating through a collection is intrinsically not a thread-safe procedure. Even when a collection is synchronized, other threads can still modify the collection, which causes the enumerator to throw an exception. To guarantee thread safety during enumeration, you can either lock the collection during the entire enumeration or catch the exceptions resulting from changes made by other threads.
