Syntax

'Declaration
<SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel := True)> _
Public NotInheritable Class ManagedProperty

'Usage
Dim instance As ManagedProperty

[SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel = true)]
public sealed class ManagedProperty

Remarks

Managed properties are the set of properties that are available to the search user experience. For more information about managed properties, see Managing Metadata.

Use the AllManagedProperties property of the Schema class to get the collection of managed properties in the Shared Service Provider's search schema.

Use an indexer to return a single managed property from the ManagedPropertyCollection object. For example, assuming the collection is assigned to a variable named mProperties, use mProperties[index] in Microsoft Visual C# or mProperties(index) in Microsoft Visual Basic, where index is a string containing the name of the managed property.

To create a managed property, use the Create() method of the ManagedPropertyCollection class. For steps on how to do this, see How to: Create a Managed Property.

To delete a managed property, use the Delete method of the ManagedProperty class. For steps on how to do this, see How to: Delete a Managed Property.

Examples

The following code example writes out the full list of managed properties to the console window. For a complete, step-by-step walkthrough of this sample code, see How to: Retrieve the Managed Properties for a Shared Services Provider.

Prerequisites
