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

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.

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

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 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));
 }
