Valeur de retour

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

Notes

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.
