Link<T> Structure

.NET Framework (current version)

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)

Syntax

generic<typename T>
public value struct Link

Type Parameters

T: The type of the elements in the deferred source.

Constructors

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

Properties

	Name	Description
	HasLoadedOrAssignedValue	Specifies whether the Link<T> has loaded or assigned a value.
	HasValue	Gets a value that specifies whether the source has a value.
	Value	Gets or sets the value assigned to or loaded by the Link<T>.

Methods

	Name	Description
	Equals(Object^)	Indicates whether this instance and a specified object are equal.(Inherited from ValueType.)
	GetHashCode()	Returns the hash code for this instance.(Inherited from ValueType.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	ToString()	Returns the fully qualified type name of this instance.(Inherited from ValueType.)

Remarks

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.
