WeakReference.IsAlive Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

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

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

Syntax

'Declaration
Public Overridable ReadOnly Property IsAlive As Boolean
public virtual bool IsAlive { 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.

Remarks

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.
