Represents a collection of ManagedProperty objects.

Inheritance hierarchy


Namespace:  Microsoft.Office.Server.Search.Administration
Assembly:  Microsoft.Office.Server.Search (in Microsoft.Office.Server.Search.dll)


<SharePointPermissionAttribute(SecurityAction.Demand, ObjectModel := True)> _
Public NotInheritable Class ManagedPropertyCollection _
    Implements IEnumerable
Dim instance As ManagedPropertyCollection
[SharePointPermissionAttribute(SecurityAction.Demand, ObjectModel = true)]
public sealed class ManagedPropertyCollection : IEnumerable


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

To add a new managed property to the collection, use the Create() method.

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.


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 Service Provider.


Ensure a Shared Service Provider is already created.
