计算工作簿公式

计算工作簿公式

请用IWorkbook->计算公式()计算工作簿公式的方法。下面的示例代码解释了该方法的用法。

示例代码

//For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C

//Create a new workbook
intrusive_ptr<IWorkbook> wb = Factory::CreateIWorkbook();

//Get first worksheet which is created by default
intrusive_ptr<IWorksheet> ws = wb->GetIWorksheets()->GetObjectByIndex(0);

//Adding a value to "A1" cell
intrusive_ptr<ICell> cell = ws->GetICells()->GetObjectByIndex(new String("A1"));
cell->PutValue(5);

//Adding a value to "A2" cell
cell = ws->GetICells()->GetObjectByIndex(new String("A2"));
cell->PutValue(15);

//Adding a value to "A3" cell
cell = ws->GetICells()->GetObjectByIndex(new String("A3"));
cell->PutValue(25);

//Adding SUM formula to "A4" cell
cell = ws->GetICells()->GetObjectByIndex(new String("A4"));
cell->SetFormula(new String("=SUM(A1:A3)"));

//Calculating the results of formulas
wb->CalculateFormula();

//Get the calculated value of the cell "A4" and print it on console
cell = ws->GetICells()->GetObjectByIndex(new String("A4"));
StringPtr sCalcuInfo = new String(L"Calculated Value of Cell A4: ");
Console::WriteLine(sCalcuInfo->StringAppend(cell->GetStringValue()));

控制台输出

这是上述示例代码的控制台输出。

 Calculated Value of Cell A4: 45
