aspose - Aspose-Cells：如何评估公式？

Question

给定以下代码：

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

如何评估单元格 [0,0] 中的公式？

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

在运行时获取/检索计算值之前，调用 Workbook.CalculateFormula() 方法计算工作簿中的所有公式，例如

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;
