Metodi

  Nome Descrizione
Metodo pubblico Equals Determines whether two instances of Member are equal. Esegue l'override di Object. . :: . .Equals(Object).
Metodo pubblico FetchAllProperties Retrieves all member properties from the server.
Metodo protetto Finalize Ereditato da Object.
Metodo pubblico GetChildren() () () () Returns a MemberCollection that contains a collection of child members for the Member.
Metodo pubblico GetChildren(Int64, Int64) Returns a MemberCollection that contains a collection of child members for the Member. The returned object contains up to count members, and begins at the position indicated by start.
Metodo pubblico GetChildren(Int64, Int64, array<MemberFilter> [] () [] []) Returns a MemberCollection that contains a collection of child members for the Member. The returned object contains up to count members, begins at the position indicated by the start parameter, and is filtered by the filters parameters.
Metodo pubblico GetChildren(Int64, Int64, array<String> [] () [] [], array<MemberFilter> [] () [] []) Returns a MemberCollection that contains a collection of child members for the Member. The returned object contains up to count members, begins at the position indicated by the start parameter, and is filtered by the filters parameters. Each member caches the properties indicated by the Array passed into the properties parameter. Note   For performance reasons, this overload should be used only if non-default member properties are needed. Default member properties include Name, UniqueName, Caption, ChildCount, Description, LevelDepth, LevelName, Parent, ParentLevel, and Type.
Metodo pubblico GetHashCode Serves as a hash function for a particular type, for use in hashing algorithms and data structures such as hash tables. Esegue l'override di Object. . :: . .GetHashCode() () () ().
Metodo pubblico GetType Ereditato da Object.
Metodo protetto MemberwiseClone Ereditato da Object.
Metodo pubblico ToString A String that contains the name of the Member. Esegue l'override di Object. . :: . .ToString() () () ().

Osservazioni

A member is an item in a hierarchy that represents one or more records in the underlying relational database. A member is the lowest level of reference used when accessing cell data in a cube.

Members are used to construct tuples, which in turn are used to construct sets. Members are organized hierarchically; a member can have other members associated with it. For example, in a time dimension that contains three levels named Year, Month, and Day, the members of the Day level are leaf members because they have no child members. The members in the Year and Month levels are nonleaf members, because each member in the Month level has at least 28 child members from the Day level and each member in the Year level has 12 child members from the Month level.

The Member encapsulates the information necessary to describe a member, including a collection of Member objects that contain child members, if applicable.

The information available to a Member depends on the parent of the Members collection from which the Member was retrieved. While the Members collection externally represents a collection of Member objects for a specified Hierarchy, Tuple, Level, or Member, the collection is internally loaded and managed in one of two ways, depending on the parent of the Hierarchy, Tuple, Level, or Member:

  • If the parent object was referenced through a CubeDef in order to retrieve metadata from the server, the collection represents the members that are defined for the parent object.

  • If the parent object was referenced through a CellSet in order to retrieve metadata from a query, the collection represents the members that are retrieved for the set (or axis) that contains the parent object.

Esempi

The following subroutine, given a Hierarchy, iterates through the Members collection and displays information for each Member:

Public Overloads Sub ListMembers(ByRef HierarchyToCheck As Hierarchy)

    ' Check the parameter before performing actions on it.
    If HierarchyToCheck Is Nothing Then
        Throw New System.ArgumentNullException("HierarchyToCheck")
    Else
        ' Iterate through the Members collection of the
        ' Hierarchy object.

        Try
            Dim memberToCheck As Member

            Debug.WriteLine("Found " & HierarchyToCheck.Members.Count & _
                " member(s) in hierarchy:")

            For Each memberToCheck In HierarchyToCheck.Members
                Debug.WriteLine("Member:  " & memberToCheck.Name)
                Debug.WriteLine("  Caption:          " & _
                    memberToCheck.Caption)
                Debug.WriteLine("  UniqueName:       " & _
                    memberToCheck.UniqueName)

                Debug.WriteLine("  No. of children:  " & _
                    memberToCheck.Children.Count)
            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

Protezione dei thread

I membri static (Shared in Visual Basic) pubblici di questo tipo sono affidabili. Non è invece garantita la sicurezza dei membri dell'istanza.
