Link(Of T) Structure
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Used to enable deferred loading of individual properties (similar to EntityRef(Of TEntity)).
Assembly: System.Data.Linq (in System.Data.Linq.dll)
The Link(Of T) type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | Link(Of T)(T) | Initializes a new instance of the Link(Of T) structure by referencing the value of the property. |
![]() | Link(Of T)(IEnumerable(Of T)) | Initializes a new instance of the Link(Of T) structure by referencing the source. |
![]() | Link(Of T)(Link(Of T)) | Initializes a new instance of the Link(Of T) structure by copying the internal state from another Link(Of T) instance. |
| Name | Description | |
|---|---|---|
![]() | HasLoadedOrAssignedValue | Specifies whether the Link(Of 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(Of T). |
| Name | Description | |
|---|---|---|
![]() | Equals | Indicates whether this instance and a specified object are equal. (Inherited from ValueType.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Returns the hash code for this instance. (Inherited from ValueType.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns the fully qualified type name of this instance. (Inherited from ValueType.) |
If you assign a deferred source (IEnumerable(Of T)) to Link(Of T), Link(Of T) loads the value by enumerating the source the first time the Value property is accessed.
