   ByVal row As Integer, _
   ByVal column As Integer _
) As Object

'Usage
 
Dim instance As CalcArray
Dim row As Integer
Dim column As Integer
Dim value As Object

Example

This example returns the number of columns and rows in the array.

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.ArrayExpression arg1 = new FarPoint.CalcEngine.ArrayExpression(knownY);
FarPoint.CalcEngine.ArrayExpression arg2 = new FarPoint.CalcEngine.ArrayExpression(knownX);
FarPoint.CalcEngine.Expression[] args = {arg1, arg2};
FarPoint.CalcEngine.Expression func = new FarPoint.CalcEngine.FunctionExpression(FarPoint.CalcEngine.FunctionInfo.SlopeFunction,args);

((FarPoint.Win.Spread.Model.IExpressionSupport)fpSpread1.ActiveSheet.Models.Data).SetExpression(0, 0, func);
FarPoint.CalcEngine.CalcArray ca = arg1.ArrayValue;
MessageBox.Show("The value in the cell is " + ca.GetValue(0, 0).ToString());
MessageBox.Show("The number of rows is " + ca.RowCount.ToString() + " and the number of columns is " + ca.ColumnCount.ToString());

((FarPoint.Web.Spread.Model.IExpressionSupport)FpSpread1.Sheets[0].DataModel).SetExpression(0, 0, func);
FarPoint.CalcEngine.CalcArray ca = arg1.ArrayValue;
TextBox1.Text = "The value in the cell is " + ca.GetValue(0, 0).ToString();
TextBox2.Text = "The number of rows is " + ca.RowCount.ToString() + " and the number of columns is " + ca.ColumnCount.ToString();
