    string propertyName
)

        propertyName:string -> Object

) : Object

Parameters

propertyName
Type: System.String

The name of the property whose value is to be retrieved.

Return Value

Type: System.Object
The value of the data source information property, or nulla null reference (Nothing in Visual Basic) if the property is not supported.

Exceptions

Exception	Condition
ArgumentNullException	The propertyName parameter is nulla null reference (Nothing in Visual Basic).

Remarks

The base class keeps a cache of values that have been retrieved, and therefore only calls this method once per data source information property. Thus, the implementation of this method need not cache values itself.

Notes to Inheritors

The base implementation of this method returns nulla null reference (Nothing in Visual Basic).
