public final class PropertyCollection implements ICollection, IEnumerable

備註

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.

[!附註]

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.

範例

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            ' A cached version of an ADOMD.NET object is no longer valid.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
