Element.GetParameter

Description:
Retrieves a parameter from the element given identifier.

Remarks:
Parameters are a generic form of data storage within elements. The parameters are visible through the Autodesk Revit user interface in the Element Properties dialog. This method uses a built in parameter identifier to access the parameter. Autodesk Revit has a large number of built in parameters that are available via static properties.
