'用途
Dim instance As Expression
Dim tuple As Tuple
Dim returnValue As MDXValue

returnValue = instance.Calculate(tuple)

        tuple:Tuple -> MDXValue 

public function Calculate(
    tuple : Tuple
) : MDXValue

參數

• tuple
  型別：Microsoft.AnalysisServices.AdomdServer. . :: . .Tuple
  The tuple under which to evaluate the MDX expression.

傳回值

型別：Microsoft.AnalysisServices.AdomdServer. . :: . .MDXValue
An MDXValue that contains the scalar result of the MDX expression.

備註

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.
