WeakReference<T> Class

.NET Framework (current version)
 

Represents a typed weak reference, which references an object while still allowing that object to be reclaimed by garbage collection.

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

System::Object
  System::WeakReference<T>

generic<typename T>
where T : ref class
[SerializableAttribute]
public ref class WeakReference sealed : ISerializable

Type Parameters

T

The type of the object referenced.

NameDescription
System_CAPS_pubmethodWeakReference<T>(T)

Initializes a new instance of the WeakReference<T> class that references the specified object.

System_CAPS_pubmethodWeakReference<T>(T, Boolean)

Initializes a new instance of the WeakReference<T> class that references the specified object and uses the specified resurrection tracking.

NameDescription
System_CAPS_pubmethodEquals(Object^)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Discards the reference to the target that is represented by the current WeakReference<T> object.(Overrides Object::Finalize().)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetObjectData(SerializationInfo^, StreamingContext)

Populates a SerializationInfo object with all the data necessary to serialize the current WeakReference<T> object.

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodSetTarget(T)

Sets the target object that is referenced by this WeakReference<T> object.

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubmethodTryGetTarget(T%)

Tries to retrieve the target object that is referenced by the current WeakReference<T> object.

A weak reference enables the garbage collector to collect an object while still allowing an application to access the object. If you need the object, you can obtain a strong reference to it and prevent it from being collected.
