Syntax
public class PageReference : ContentReference, IComparable, IReadOnly<ContentReference>, IComparable<ContentReference>, IEquatable<ContentReference>, IReadOnly<PageReference>, IReadOnly
Remarks

Instead of using raw integer IDs, the ID is packaged in a PageReference structure. A page can have several versions and even be located on another physical server. This information is also stored inside the structure.

PageReference(String)

Initialize a new PageReference from a string in the format pageID[_workID[_remoteSite]] or - throws EPiServerException on invalid argument

Declaration
public PageReference(string complexReference)
Parameters
Type Name Description

Returns a PageReference that references the current page.

Declaration
public static readonly PageReference SelfReference
Field Value

PageReference

Properties

RemoteSite

A string that identifies a remote site as defined in the list of remote sites for this installation.

Declaration
[Obsolete("Use ProviderName property instead")]
public string RemoteSite { get; set; }
Property Value
Type Description
System.String

True if it is a remote reference.
Remarks

To see if the PageReference is a remote link, use the IsRemote() method rather than looking at the RemoteSite.

Exceptions
Type Condition
System.NotSupportedException

Thrown if the instance is read-only.

Methods

Copy()

Copies this instance.

Declaration
public PageReference Copy()
Returns
Type Description
PageReference

CreateReferenceToPublishedPage()

Creates a new reference to the published version of page. That is with same ID and ProviderName but without WorkID.

Declaration
[Obsolete("This method has performance implications since it always clones objects, use ToReferenceWithoutVersion extension method instead")]
public PageReference CreateReferenceToPublishedPage()
Returns
Type Description
PageReference

CreateWritableClone()

Create a copy of the current object instance that is writable.

Declaration
public PageReference CreateWritableClone()
Returns
Type Description
PageReference

A new copy of the object.
Remarks

The cloning is a deep-copy.

IsAnyVersion()

Indicates if the PageReference references a specific version or may be used to load any available version.

Declaration
[Obsolete("Use property GetPublishedOrLatest instead")]
public bool IsAnyVersion()
Returns
Type Description
System.Boolean

true if AnyVersion; otherwise, false.
Remarks

This method only returns true if the PageReference object was created via the PageReference(Int32, Boolean) constructor. Typically, that constructor is used when you want to load the latest version a page regardless if it's published or not.

When a PageReference with GetAnyVersion is set to true is passed to GetPage(PageReference) the returned PageData object will be, in order of preference:

If AnyVersion is set to true, any value assigned to WorkID will be ignored.

IsNullOrEmpty(PageReference)

Determines whether the specified page link is null or empty.

Declaration
public static bool IsNullOrEmpty(PageReference pageLink)

public bool IsRemote()
Returns
Type Description
System.Boolean

True if it is a remote reference.
Remarks

A PageReference can point to an external site as indicated by the RemoteSite property.

IsValue(PageReference)

Determines whether the passed PageReference is initiated with a value.

Declaration
public static bool IsValue(PageReference pageLink)
Parameters
Type Name Description
PageReference pageLink

The PageReference object to be checked.
Returns
Type Description
System.Boolean

true if the passed PageReference is not null and does not equal EmptyReference or SelfReference; otherwise, false.

Parse(String)

Parse and return a PageReference from a string.

Declaration
public static PageReference Parse(string s)
Parameters
Type Name Description
System.String s

The string, in the format pageID[_workID[_remoteSite]].

In order to successfully parse a FURL with ParserUrl, first convert the FURL to an internal url - use the UrlRewriteProvider.ConvertToInternal method.

TryParse(String, out PageReference)

Create a new PageReference from a string in the format pageID[_workID[_remoteSite]]

Declaration
public static bool TryParse(string complexReference, out PageReference result)
