Inheritance Hierarchy

System.Object
  Microsoft.SharePoint.SPFileVersion

Namespace:  Microsoft.SharePoint
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)

Syntax

<SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel := True)> _
<SharePointPermissionAttribute(SecurityAction.InheritanceDemand, ObjectModel := True)> _
Public Class SPFileVersion

Dim instance As SPFileVersion
[SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel = true)]
[SharePointPermissionAttribute(SecurityAction.InheritanceDemand, ObjectModel = true)]
public class SPFileVersion

Remarks

When a file becomes a version, its properties are maintained with the version. This includes the check-in comment and other information for the file.

Use the Versions property of the SPFile class to return an SPFileVersionCollection object that represents the collection of versions for a file. Use an indexer to return a single version from the collection. For example, if the collection is assigned to a variable named collVersions, use collVersions[index] in C#, or collVersions(index) in Visual Basic, where index is the index number of the version in the collection. Otherwise, use the GetVersionFromID method to return a single version from the collection.

If file versioning is enabled for a document library, calling the CheckIn method of the SPFile class after using the CheckOut method creates a version of the file. In the same way, calling the SaveBinary method of the SPFile class also creates a version.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
