Exemplos

The following subroutine, given a Level, iterates through the LevelPropertyCollection collection and displays information about each level property:

Public Overloads Sub ListLevelPropertyCollection(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 LevelProperties collection of the
        ' Level object.

        Try
            Dim propToCheck As LevelProperty

            Debug.WriteLine("Found " & LevelToCheck.LevelProperties.Count & _
                " level properties in level:")

            For Each propToCheck In LevelToCheck.LevelProperties
                Debug.WriteLine("Level Property:  " & propToCheck.Name)
                Debug.WriteLine("  Caption:        " & _
                    propToCheck.Caption)
                Debug.WriteLine("  Description:    " & _
                    propToCheck.Description)
            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            ' A cached version of an ADOMD.NET object is no longer valid.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
