Visual Basic
C#

'宣言
 
Function EvaluateExpression( _
   ByVal row As Integer, _
   ByVal column As Integer, _
   ByVal expression As Expression _
) As Object

object EvaluateExpression( 
   int row,
   int column,
   Expression expression
)

パラメータ

評価された式を含む Object

使用例

次のサンプルコードは、式を評価し、指定した行および列のセルに対する結果のオブジェクトを返します。

C#
Visual Basic

FarPoint.Win.Spread.Model.IExpressionSupport ems; 
FarPoint.CalcEngine.Expression one = new FarPoint.CalcEngine.DoubleExpression(1.0); 
FarPoint.CalcEngine.Expression two = new FarPoint.CalcEngine.DoubleExpression(2.0); 
FarPoint.CalcEngine.Expression oneplustwo = new FarPoint.CalcEngine.BinaryOperatorExpression(FarPoint.CalcEngine.BinaryOperatorInfo.AddOperator, one, two); 
ems = (FarPoint.Win.Spread.Model.IExpressionSupport)fpSpread1.ActiveSheet.Models.Data; 
ems.SetExpression(0, 0, oneplustwo); 
FarPoint.CalcEngine.Expression exp;
exp = ems.GetExpression(0, 0);
FarPoint.Win.Spread.Model.IExpressionSupport2 es;
es = (FarPoint.Win.Spread.Model.IExpressionSupport2)fpSpread1.ActiveSheet.Models.Data;
MessageBox.Show("The evaluated expression is " + es.EvaluateExpression(0, 0, exp).ToString());

ems = FpSpread1.ActiveSheet.Models.Data
ems.SetExpression(0, 0, oneplustwo)
Dim exp As FarPoint.CalcEngine.Expression
exp = ems.GetExpression(0, 0)
Dim es As FarPoint.Win.Spread.Model.IExpressionSupport2
es = FpSpread1.ActiveSheet.Models.Data
MessageBox.Show("The evaluated expression is " & es.EvaluateExpression(0, 0, exp).ToString())
