MemberCollection Class

 

Gets a read-only, on-demand collection of Member objects contained by a Position, a Level, or a Tuple.

Namespace:   Microsoft.AnalysisServices.AdomdClient
Assembly:  Microsoft.AnalysisServices.AdomdClient (in Microsoft.AnalysisServices.AdomdClient.dll)

System.Object
  Microsoft.AnalysisServices.AdomdClient.MemberCollection

public sealed class MemberCollection : ICollection, IEnumerable

NameDescription
System_CAPS_pubpropertyCount

Gets the number of Member objects in the collection.

System_CAPS_pubpropertyIsSynchronized

Gets a value indicating whether access to the collection is synchronized (thread safe).

System_CAPS_pubpropertyItem[Int32]

Gets the specified Member from the collection by its index. In C#, this property is the indexer for the MemberCollection class.

System_CAPS_pubpropertyItem[String]

Gets the specified Member from the collection by its name. In C#, this property is the indexer for the MemberCollection class.

System_CAPS_pubpropertySyncRoot

Gets an object that can be used to synchronize access to the collection.

NameDescription
System_CAPS_pubmethodCopyTo(Member[], Int32)

Copies the elements of the collection to the specified array.

System_CAPS_pubmethodEquals(Object)

(Inherited from Object.)

System_CAPS_pubmethodFind(String)

Returns the specified Member from the collection by its name.

System_CAPS_pubmethodGetEnumerator()

Gets an Enumerator for iterating through the collection.

System_CAPS_pubmethodGetHashCode()

(Inherited from Object.)

System_CAPS_pubmethodGetType()

(Inherited from Object.)

System_CAPS_pubmethodToString()

(Inherited from Object.)

NameDescription
System_CAPS_pubinterfaceSystem_CAPS_privmethodICollection.CopyTo(Array, Int32)

Copies the elements of the MemberCollection to the destination array, starting at a particular array index.

System_CAPS_pubinterfaceSystem_CAPS_privmethodIEnumerable.GetEnumerator()

Gets the enumerator that iterates through the MemberCollection.

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.

Legacy Code Example

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

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
