Contains a read-only, on-demand collection of Dimension objects contained in a CubeDef.

Inheritance Hierarchy

System.Object
Microsoft.AnalysisServices.AdomdClient.DimensionCollection

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

Syntax

'Declaration
Public NotInheritable Class DimensionCollection _
    Implements ICollection, IEnumerable
'Usage
Dim instance As DimensionCollection

public sealed class DimensionCollection : ICollection, 
    IEnumerable

public ref class DimensionCollection sealed : ICollection, 
    IEnumerable

[<SealedAttribute>]
type DimensionCollection =  
    class
        interface ICollection
        interface IEnumerable
    end

public final class DimensionCollection implements ICollection, IEnumerable

The DimensionCollection type exposes the following members.

Properties

	Name	Description
	Count	Gets the number of Dimension objects in the collection.
	IsSynchronized	Gets a value indicating whether access to the collection is synchronized (thread safe).
	Item[Int32]	Gets the specified Dimension from the collection by its index. In C#, this property is the indexer for the DimensionCollection class.
	Item[String]	Gets the specified Dimensionfrom the collection by its name. In C#, this property is the indexer for the DimensionCollection class.
	SyncRoot	Gets an object that can be used to synchronize access to the collection.

Methods

	Name	Description
	CopyTo	Copies the elements of the collection to the specified array.
	Equals	(Inherited from Object.)
	Finalize	(Inherited from Object.)
	Find	Gets the specified Dimension from the collection by its name.
	GetEnumerator	Gets an Enumerator for iterating through the collection.
	GetHashCode	(Inherited from Object.)
	GetType	(Inherited from Object.)
	MemberwiseClone	(Inherited from Object.)
	ToString	(Inherited from Object.)

Examples

The following subroutine, given a CubeDef, iterates through the DimensionCollection collection and displays information about each dimension:

Public Sub ListDimensionCollection(ByRef CubeToCheck As CubeDef)

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

        Try
            Dim dimToCheck As Dimension

            Debug.WriteLine("Found " & CubeToCheck.Dimensions.Count & _
                " dimensions in cube:")

            For Each dimToCheck In CubeToCheck.Dimensions
                Debug.WriteLine("Dimension:  " & dimToCheck.Name)
                Debug.WriteLine("  Caption:        " & _
                    dimToCheck.Caption)
                Debug.WriteLine("  Description:    " & _
                    dimToCheck.Description)
                Debug.WriteLine("  UniqueName:     " & _
                    dimToCheck.UniqueName)
                Debug.WriteLine("  The dimension " & _
                    IIf(dimToCheck.WriteEnabled = True, "is", "is not") & _
                    " write-enabled.")
            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
