LinkedListNode(Of T) Class
Represents a node in a LinkedList(Of T). This class cannot be inherited.
Assembly: System (in System.dll)
| Name | Description | |
|---|---|---|
![]() | LinkedListNode(Of T)(T) | Initializes a new instance of the LinkedListNode(Of T) class, containing the specified value. |
| Name | Description | |
|---|---|---|
![]() | List | Gets the LinkedList(Of T) that the LinkedListNode(Of T) belongs to. |
![]() | Next | Gets the next node in the LinkedList(Of T). |
![]() | Previous | Gets the previous node in the LinkedList(Of T). |
![]() | Value | Gets the value contained in the node. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified object is equal to the current object.(Inherited from Object.) |
![]() | GetHashCode() | Serves as the default hash function. (Inherited from Object.) |
![]() | GetType() | |
![]() | ToString() | Returns a string that represents the current object.(Inherited from Object.) |
Each element of the LinkedList(Of T) collection is a LinkedListNode(Of T). The LinkedListNode(Of T) contains a value, a reference to the LinkedList(Of T) that it belongs to, a reference to the next node, and a reference to the previous node.
The following code example creates a LinkedListNode(Of T), adds it to a LinkedList(Of T), and tracks the values of its properties as the LinkedList(Of T) changes.
