ArrayExpression Constructor

Visual Basic
C#

'Declaration
 
Public Function New( _
   ByVal values(,) As Object _
)

'Usage
 
Dim values() As Object
 
Dim instance As New ArrayExpression(values)

public ArrayExpression( 
   object[,] values
)

Parameters

values: Array of constant values

Exception	Description
System.ArgumentNullException	values is a null reference (Nothing in Visual Basic)

This example creates an expression with an array of constant values.

C#

object[,] knownY = {{2.0, 3.0, 9.0, 1.0, 8.0, 7.0, 5.0}};
object[,] knownX = {{6.0, 5.0, 11.0, 7.0, 5.0, 4.0, 4.0}};
FarPoint.CalcEngine.Expression arg1 = new FarPoint.CalcEngine.ArrayExpression(knownY);
FarPoint.CalcEngine.Expression arg2 = new FarPoint.CalcEngine.ArrayExpression(knownX);
FarPoint.CalcEngine.Expression[] args = new FarPoint.CalcEngine.Expression[] {arg1, arg2};
FarPoint.CalcEngine.Expression func = new FarPoint.CalcEngine.FunctionExpression(FarPoint.CalcEngine.FunctionInfo.SlopeFunction,args);
//Spread for Windows Forms
((FarPoint.Win.Spread.Model.IExpressionSupport)fpSpread1.ActiveSheet.Models.Data).SetExpression(0, 0, func);
//Spread for Web Forms
((FarPoint.Web.Spread.Model.IExpressionSupport)FpSpread1.Sheets[0].DataModel).SetExpression(0, 0, func);

Visual Basic

Dim x As Object(,) = {{2.0, 3.0, 9.0, 1.0, 8.0, 7.0, 5.0}}
Dim y As Object(,) = {{6.0, 5.0, 11.0, 7.0, 5.0, 4.0, 4.0}}
Dim arg1 As New FarPoint.CalcEngine.ArrayExpression(x)
Dim arg2 As New FarPoint.CalcEngine.ArrayExpression(y)
Dim args() As FarPoint.CalcEngine.Expression = {arg1, arg2}
Dim func As New FarPoint.CalcEngine.FunctionExpression(FarPoint.CalcEngine.FunctionInfo.SlopeFunction, args)
'Spread for Windows Forms
CType(FpSpread1.ActiveSheet.Models.Data, FarPoint.Win.Spread.Model.IExpressionSupport).SetExpression(0, 0, func)
'Spread for Web Forms
CType(FpSpread1.Sheets(0).DataModel, FarPoint.Web.Spread.Model.IExpressionSupport).SetExpression(0, 0, func)
