Represents a collection of SPFeature objects.
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
Use the Features property of the Microsoft.SharePoint.Administration.SPWebApplication, Microsoft.SharePoint.Administration.SPWebService, SPSite, or SPWeb class to get the collection of Features that are activated in the Web application, Web service, site collection, or site. Use the SiteFeatures or WebFeatures property of the SPContext class to get the collection of activated Features for the current site collection or site.
The existence of a Feature object within one of these collections indicates that it has been activated within the given scope. To activate a Feature, you must install it in the server farm; to install a feature, use an Add method of the SPFeatureCollection class.
Use an indexer to return a single Feature object from the collection. For example, if the collection is assigned to a variable named collFeatures, use collFeatures[index] in C#, or collFeatures(index) in Visual Basic, where index is the GUID of the Feature object.
The following code example activates a Web site-scoped Feature with the specified title in all the subsites of a specific site collection.
Dim oCultureInfo As New System.Globalization.CultureInfo(1033) Dim collFeatureDefinitions As SPFeatureDefinitionCollection = SPFarm.Local.FeatureDefinitions For Each oFeatureDefinition As SPFeatureDefinition In collFeatureDefinitions If oFeatureDefinition.GetTitle(oCultureInfo) = "Feature_Title" Then Dim guidFeatureDefinitionID As Guid = oFeatureDefinition.Id Dim collWebsites As SPWebCollection = SPContext.Current.Site.AllWebs("Site").Webs For Each oWebsite As SPWeb In collWebsites If oFeatureDefinition.Scope = SPFeatureScope.Web Then Dim collFeatureCollection As SPFeatureCollection = oWebsite.Features Dim oFeature As SPFeature = collFeatureCollection.Add(guidFeatureDefinitionID) Response.Write(SPEncode.HtmlEncode(oFeature.Definition.GetTitle(oCultureInfo)) & " feature added on " & oWebsite.Title & "<BR>") End If oWebsite.Dispose() Next oWebsite End If Next oFeatureDefinition
Certain objects implement the IDisposable interface, and you must avoid retaining these objects in memory after they are no longer needed. For information about good coding practices, see Disposing Objects.
