Notes
Although the MemberPropertyCollection collection externally represents a collection of MemberProperty objects for a specified Member, the collection is internally loaded and managed in one of two ways, depending on the parentage of the Member:
If the Member was referenced through the use of a CubeDef in order to retrieve metadata from the server, the collection represents the member properties that are defined for the level of the member represented by the Member.
If the Member was referenced through the use of a CellSet in order to retrieve metadata from a query, the collection represents the member properties that are retrieved for the set (or axis) containing the member represented by the Member.
Exemples
The following subroutine, given a Member, iterates through the MemberPropertyCollection collection and displays information for each member property:
Public Sub ListMemberPropertyCollection(ByRef MemberToCheck As Member)
' Check the parameter before performing actions on it.
If MemberToCheck Is Nothing Then
Throw New System.ArgumentNullException("MemberToCheck")
Else
' Iterate through the MemberProperties collection of the
' Member object.
Try
Dim propToCheck As MemberProperty
Debug.WriteLine("Found " & _
MemberToCheck.MemberProperties.Count & _
" member properties in member:")
For Each propToCheck In MemberToCheck.MemberProperties
Debug.WriteLine("Member Property: " & propToCheck.Name)
Debug.WriteLine(" Value: " & _
propToCheck.Value)
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' A cached version of an ADOMD.NET object is no longer valid.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
