Gets a read-only collection of Property objects contained by a CellSet.

Namespace: Microsoft.AnalysisServices.AdomdClient
Assembly: Microsoft.AnalysisServices.AdomdClient (in microsoft.analysisservices.adomdclient.dll)

Syntax

'Declaration
<DefaultMemberAttribute("Item")> _
Public NotInheritable Class PropertyCollection
    Implements ICollection, IEnumerable

[DefaultMemberAttribute("Item")] 
public sealed class PropertyCollection : ICollection, IEnumerable

[DefaultMemberAttribute(L"Item")] 
public ref class PropertyCollection sealed : ICollection, IEnumerable

/** @attribute DefaultMemberAttribute("Item") */ 
public final class PropertyCollection implements ICollection, IEnumerable

DefaultMemberAttribute("Item") 
public final class PropertyCollection implements ICollection, IEnumerable

Remarks

The PropertyCollection is used by a CellSet to represent the axes returned by a query. Each Property contained by an PropertyCollection represents a set of congruent tuples organized along one or more hierarchies.

Note

The filter Property is not contained in this collection. To access the filter Property, you must reference the OlapInfo.AxesInfo.FilterAxes property of the CellSet.

Example

The following subroutine, given a CellSet, iterates through the PropertyCollection (represented by the Axes property of the CellSet) and displays information for each Property.

Public Sub ListAxes(ByRef cellsetToCheck As CellSet)

    ' Check the parameter before performing actions on it.
    If cellsetToCheck Is Nothing Then
        Throw New System.ArgumentNullException("cellsetToCheck")
    Else
        ' Iterate through the axes of the
        ' CellSet object. The Axes property of the 
        ' CellSet object returns a reference to the
        ' PropertyCollection object.

        Try
            Dim PropertyToCheck As Property

            Debug.WriteLine("Found " & cellsetToCheck.Axes.Count & _
                " axes in cellset:")

            For Each PropertyToCheck In cellsetToCheck.Axes

                Debug.WriteLine("  Name:  " & _
                    PropertyToCheck.Name)
            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
