WeakReference::IsAlive Property

Gets an indication whether the object referenced by the current WeakReference object has been garbage collected.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public:
virtual property bool IsAlive {
	bool get ();
}

Property Value

Type: System::Boolean
true if the object referenced by the current WeakReference object has not been garbage collected and is still accessible; otherwise, false.

Because an object could potentially be reclaimed for garbage collection immediately after the IsAlive property returns true, using this property is not recommended unless you are testing only for a false return value.
