       ByVal oper As BinaryOperatorInfo, _
       ByVal arg0 As Expression, _
       ByVal arg1 As Expression _
    )
    'Usage
     
    Dim oper As BinaryOperatorInfo
    Dim arg0 As Expression
    Dim arg1 As Expression
     
    Dim instance As New BinaryOperatorExpression(oper, arg0, arg1)

    Example
    This example creates a new expression with a binary operator applied to a pair of operands.
    FarPoint.CalcEngine.Expression arg1 = new FarPoint.CalcEngine.DoubleExpression(1.0);
    FarPoint.CalcEngine.Expression arg2 = new FarPoint.CalcEngine.DoubleExpression(2.0);
    FarPoint.CalcEngine.Expression oneplustwo = new FarPoint.CalcEngine.BinaryOperatorExpression(FarPoint.CalcEngine.BinaryOperatorInfo.AddOperator,arg1, arg2);
    //Spread for Windows Forms
    ((FarPoint.Win.Spread.Model.IExpressionSupport)fpSpread1.ActiveSheet.Models.Data).SetExpression(0, 0, oneplustwo);
    //Spread for Web Forms
    ((FarPoint.Web.Spread.Model.IExpressionSupport)FpSpread1.Sheets[0].DataModel).SetExpression(0, 0, oneplustwo);
    Dim arg1 As FarPoint.CalcEngine.Expression
    Dim arg2 As FarPoint.CalcEngine.Expression
    Dim oneplustwo As FarPoint.CalcEngine.Expression
    arg1 = New FarPoint.CalcEngine.DoubleExpression(1.0)
    arg2 = New FarPoint.CalcEngine.DoubleExpression(2.0)
