Gets the number of Hierarchy objects in the collection.
Gets a value indicating whether access to the collection is synchronized (thread safe).
Gets the specified Hierarchy from the collection by its index. In C#, this property is the indexer for the class.
Gets the Hierarchy from the collection by its specified name. In C#, this property is the indexer for the class.
Gets an object that can be used to synchronize access to the collection.
Copies the elements of the collection to the specified array.
Gets the specified Hierarchy from the collection by its name.
Gets an enumerator for iterating through the collection.
While the Hierarchy objects, the collection is internally loaded and managed in one of two ways, depending on the parent of the collection:externally represents a collection of
If the parent object was referenced as a result of a request for metadata, as in the case of a Dimension referenced from a CubeDef, the collection represents the members referenced by the definition of the parent object.
The following subroutine, given a Dimension, iterates through the collection and displays information about each hierarchy:
Public Overloads Sub ListHierarchies(ByRef DimToCheck As Dimension) ' Check the parameter before performing actions on it. If DimToCheck Is Nothing Then Throw New System.ArgumentNullException("DimToCheck") Else ' Iterate through the Hierarchies collection of the ' Dimension object. Try Dim hierToCheck As Hierarchy Debug.WriteLine("Found " & DimToCheck.Hierarchies.Count & _ " hierarchies in dimension:") For Each hierToCheck In DimToCheck.Hierarchies Debug.WriteLine("Hierarchy: " & hierToCheck.Name) Debug.WriteLine(" Caption: " & _ hierToCheck.Caption) Debug.WriteLine(" Description: " & _ hierToCheck.Description) Debug.WriteLine(" UniqueName: " & _ hierToCheck.UniqueName) Next Catch ex As AdomdConnectionException ' The connection could not be opened or was disconnected. ' This error can occur at any time, if the provider is ' disconnected from the server. Debug.WriteLine(ex) Throw ex Catch ex As AdomdErrorResponseException ' A response is received from a provider which indicates an error. Debug.WriteLine(ex) Throw ex Catch ex As AdomdUnknownResponseException ' A response has been returned from the provider that ' was not understood. Debug.WriteLine(ex) Throw ex Catch ex As AdomdCacheExpiredException ' A cached version of an ADOMD.NET object is no longer valid. ' This error is typically raised when reviewing metadata. Debug.WriteLine(ex) Throw ex Catch ex As AdomdException ' Any other error raised by ADOMD.NET. Debug.WriteLine(ex) Throw ex Catch ex As Exception ' Any other error. Debug.WriteLine(ex) Throw ex End Try End If End Sub
