EvaluateExpression メソッド (IExpressionSupport2)

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。

構文

Visual Basic
C#

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

'使用法
 
Dim instance As IExpressionSupport2
Dim row As Integer
Dim column As Integer
Dim expression As Expression
Dim value As Object
 
value = instance.EvaluateExpression(row, column, expression)

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

パラメータ

row: 基本セルの行インデックス
column: 基本セルの列インデックス
expression: 評価する式

戻り値の型

評価された式を含む Object

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());

Dim ems As FarPoint.Win.Spread.Model.IExpressionSupport
Dim one As FarPoint.CalcEngine.Expression
Dim two As FarPoint.CalcEngine.Expression
Dim oneplustwo As FarPoint.CalcEngine.Expression
one = New FarPoint.CalcEngine.DoubleExpression(1.0)
two = New FarPoint.CalcEngine.DoubleExpression(2.0)
oneplustwo = New FarPoint.CalcEngine.BinaryOperatorExpression(FarPoint.CalcEngine.BinaryOperatorInfo.AddOperator, one, two)
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())
