RankParamCollection Class

Represents a collection of RankingParameter objects.


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

[SharePointPermissionAttribute(SecurityAction.Demand, ObjectModel = true)]
public sealed class RankParamCollection : IEnumerable

Use the RankingParameters() property of the Ranking class to get the collection of ranking parameters for a Shared Service Provider.

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


You cannot add new ranking parameters, or remove or change the names of existing parameters; you can modify only the ranking parameter's value.

The following code example writes out the ranking parameter names and built-in values to the console window.


Ensure a Shared Service Provider is already created.
