Verifiera att cellvärde uppfyller datavalideringsregler med C++

Introduktion

Aspose.Cells tillhandahåller metoden Cell.GetValidationValue() för att validera cellvärden programmässigt. Om värdet i en cell inte uppfyller datavalideringsregeln som tillämpats på den cellen, returnerar den False, annars True.

Följande exempel visar hur metoden Cell.GetValidationValue() fungerar. Först anger den värdet 3 i C1. Eftersom detta inte uppfyller datavalideringsregeln, returnerar metoden False. Sedan anger den värdet 15 i C1. Eftersom detta värde uppfyller datavalideringsregeln, returnerar den True. På samma sätt returnerar den False för värdet 30.

#include <iostream>
#include "Aspose.Cells.h"
using namespace Aspose::Cells;

int main()
{
    Aspose::Cells::Startup();

    // Source directory path
    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");

    // Instantiate the workbook from sample Excel file
    Workbook workbook(srcDir + u"sample.xlsx");

    // Access the first worksheet
    Worksheet worksheet = workbook.GetWorksheets().Get(0);

    // Access Cell C1
    // Cell C1 has the Decimal Validation applied on it.
    // It can take only the values Between 10 and 20
    Cell cell = worksheet.GetCells().Get(u"C1");

    // Enter 3 inside this cell
    // Since it is not between 10 and 20, it should fail the validation
    cell.PutValue(3);

    // Check if number 3 satisfies the Data Validation rule applied on this cell
    std::cout << "Is 3 a Valid Value for this Cell: " << cell.GetValidationValue() << std::endl;

    // Enter 15 inside this cell
    // Since it is between 10 and 20, it should succeed the validation
    cell.PutValue(15);

    // Check if number 15 satisfies the Data Validation rule applied on this cell
    std::cout << "Is 15 a Valid Value for this Cell: " << cell.GetValidationValue() << std::endl;

    // Enter 30 inside this cell
    // Since it is not between 10 and 20, it should fail the validation again
    cell.PutValue(30);

    // Check if number 30 satisfies the Data Validation rule applied on this cell
    std::cout << "Is 30 a Valid Value for this Cell: " << cell.GetValidationValue() << std::endl;

    Aspose::Cells::Cleanup();
}

Output

Is 3 a Valid Value for this Cell: False

Is 15 a Valid Value for this Cell: True

Is 30 a Valid Value for this Cell: False
