    public void SetCustomProperties( 
       IEnumerable<CIMStringMap> customProperties
    )
    Public Sub SetCustomProperties( _
       ByVal customProperties As IEnumerable(Of CIMStringMap) _
    )

    The collection of custom properties
    Exceptions
    ExceptionDescription

    Remarks
    This method was created so developers have a way to uniquely assign a value or multiple values to an element that can not be changed in the UI and therefore provides a predictable way to find an element. You can overwrite values simply be reentering the same key with a different value in the input collection. There are no methods to remove keys.
    Requirements
