Namespace: Microsoft.SharePoint
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
Syntax
'Declaration
Public Sub RestoreByID ( _
vid As Integer _
)
'Usage
Dim instance As SPFileVersionCollection
Dim vid As Integer
instance.RestoreByID(vid)
public void RestoreByID(
int vid
)
Parameters
vid
Type: System.Int32The version to restore.
Remarks
If versioning is enabled for the document library and the file is not checked out, the current file becomes the most recent version when a version is restored.
Using the RestoreByID method is the same as using a combination of the OpenBinary method of the SPFileVersion class and the SaveBinary method of the SPFile class, as in myVersion.File.SaveBinary(myVersions[5].OpenBinary). However, the RestoreByID method is more efficient.
