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。
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());
