Aspose-Cells: How do I evaluate a formula?

Given the following code:

using Aspose.Cells
// {...}  
Workbook workbook = new Workbook();  
Worksheet virtualWorksheet = workbook.Worksheets[0];  
virtualWorksheet.Cells[0, 0].Formula ="=1<2";

How do I evaluate the formula in Cell [0,0]?

bool isCellTrue = virtualWorksheet.Cells[0, 0].BoolValue;开发者_StackOverflow // will generate an exception at run-time

Call Workbook.CalculateFormula() method to calculate all the formulas in the workbook before getting/retrieving the calculated value at runtime, e.g.

Workbook workbook = new Workbook(); 
Worksheet virtualWorksheet = workbook.Worksheets[0]; 
virtualWorksheet.Cells[0, 0].Formula ="=1<2";
workbook.CalculateFormula(); 
bool isCellTrue = virtualWorksheet.Cells[0, 0].BoolValue;
