Syntax

'Declaration

    propertyName As String _
) As Object

    string propertyName
)

virtual Object^ RetrieveValue(
    String^ propertyName

override RetrieveValue : 
        propertyName:string -> Object 
protected function RetrieveValue(

Parameters

  • propertyName
    Type: System.String
    The name of property whose value is retrieved.

Return Value

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

Exceptions

Exception Condition
ArgumentNullException

The propertyName parameter is null.

Remarks

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

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