Link(T) Structure

Link<T> Structure

Used to enable deferred loading of individual properties (similar to EntityRef<TEntity>).

Namespace:  System.Data.Linq
Assembly:  System.Data.Linq (in System.Data.Linq.dll)

generic<typename T>
public value class Link

Type Parameters


The type of the elements in the deferred source.

The Link<T> type exposes the following members.

Public methodLink<T>(T)Initializes a new instance of the Link<T> structure by referencing the value of the property.
Public methodLink<T>(IEnumerable<T>)Initializes a new instance of the Link<T> structure by referencing the source.
Public methodLink<T>(Link<T>)Initializes a new instance of the Link<T> structure by copying the internal state from another Link<T> instance.

Public propertyHasLoadedOrAssignedValueSpecifies whether the Link<T> has loaded or assigned a value.
Public propertyHasValueGets a value that specifies whether the source has a value.
Public propertyValueGets or sets the value assigned to or loaded by the Link<T>.

Public methodEqualsIndicates whether this instance and a specified object are equal. (Inherited from ValueType.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from ValueType.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodToStringReturns the fully qualified type name of this instance. (Inherited from ValueType.)

If you assign a deferred source (IEnumerable<T>) to Link<T>, Link<T> loads the value by enumerating the source the first time the Value property is accessed.
