HybridDictionary.IsSynchronized Property

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

[Visual Basic]
Public Overridable ReadOnly Property IsSynchronized As Boolean  _
   Implements ICollection.IsSynchronized
[C#]
public virtual bool IsSynchronized {get;}
[C++]
public: __property virtual bool get_IsSynchronized();
[JScript]
public function get IsSynchronized() : Boolean;

Property Value

This property always returns false.

Implements

ICollection.IsSynchronized

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 could 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.

[Visual Basic, C#] The following code example shows how to lock the collection using the SyncRoot during the entire enumeration:

[C#] 
HybridDictionary myCollection = new HybridDictionary();
 lock( myCollection.SyncRoot ) {
 foreach ( Object item in myCollection ) {
 // Insert your code here.
 }
}
[Visual Basic] 
Dim myCollection As New HybridDictionary()
Dim item As Object
SyncLock myCollection.SyncRoot
 For Each item In myCollection
 ' Insert your code here.
 Next item
End SyncLock
