Count | Gets the number of Member objects in the collection. | |
IsSynchronized | Gets a value indicating whether access to the collection is synchronized (thread safe). | |

Comentarios
Although the MemberCollection externally represents a collection of Member objects, the collection is internally loaded and managed in one of two ways, depending on the parent of the collection:
If the parent object was referenced as a result of a query, as in the case of a Tuple, the collection represents the members referenced by that query.
If the parent object was referenced as a result of a request for metadata, the collection represents the members referenced by the definition of the parent object.
Ejemplos
The following subroutine, given a Level, iterates through the MemberCollection and displays information for each member.
Public Overloads Sub ListMembers(ByRef LevelToCheck As Level)
' Check the parameter before performing actions on it.
If LevelToCheck Is Nothing Then
Throw New System.ArgumentNullException("LevelToCheck")
Else
' Iterate through the Members collection of the
' Level object.
Try
Dim memberToCheck As Member
Debug.WriteLine("Found " & LevelToCheck.GetMembers().Count& _
" member(s) in level:")
For Each memberToCheck In LevelToCheck.GetMembers()
Debug.WriteLine("Member: " & memberToCheck.Name)
Debug.WriteLine(" Caption: " & _
memberToCheck.Caption)
Debug.WriteLine(" UniqueName: " & _
memberToCheck.UniqueName)
' Note that the Children property loads a collection
' of Member objects on demand and
' therefore, slows performance when first
' referenced--you should instead use the
' ChildCount property.
Debug.WriteLine(" No. of children: " & _
memberToCheck.ChildCount)
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' A cached version of an ADOMD.NET object is no longer valid.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
