WeakReference Constructor (Object, Boolean)

.NET Framework 4.5

Initializes a new instance of the WeakReference class, referencing the specified object and using the specified resurrection tracking.

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

Syntax

C++

public WeakReference(
	Object target,
	bool trackResurrection
)

Parameters

target: Type: System.Object
An object to track.

trackResurrection: Type: System.Boolean
Indicates when to stop tracking the object. If true, the object is tracked after finalization; if false, the object is only tracked until finalization.

Remarks

If trackResurrection is false, a short weak reference is created. If trackResurrection is true, a long weak reference is created.

Examples

The following example creates a cache of data objects with short weak references. This example is part of a larger example provided for the WeakReference class.

 // Add data objects with a  
 // short weak reference to the cache. 
for (int i = 0; i < count; i++)
 {
     _cache.Add(i, new WeakReference(new Data(i), false));
 }
