Parametri

tuple
The tuple under which to evaluate the MDX expression.

Valore restituito

An MDXValue that contains the scalar result of the MDX expression.

Osservazioni

The type of the MDXValue is a scalar value, such as an integer, a double, or a string. The MDXValue that is returned can be cast using one of the To methods, such as ToInt32, ToDouble, or ToString. The MDXValue can also be cast by language-specific casting.

To retrieve a non-scalar value, such as a Set, Tuple, or Member, after evaluating an MDX expression, use the CalculateMdxObject method.
