//Source directory path
StringPtr dirPath = new String("..\\Data\\LoadingSavingAndConverting\\");

//Output directory path
StringPtr outPath = new String("..\\Data\\Output\\");

//Path of input csv file
StringPtr srcReadWriteCSV = dirPath->StringAppend(new String(L"srcReadWriteCSV.csv"));

//Path of output csv file
StringPtr outReadWriteCSV = outPath->StringAppend(new String(L"outReadWriteCSV.csv"));

//Read source csv file
intrusive_ptr<IWorkbook> wb = Factory::CreateIWorkbook(srcReadWriteCSV);

//Access first worksheet
intrusive_ptr<IWorksheet> ws = wb->GetIWorksheets()->GetObjectByIndex(0);

//Access cell A1
intrusive_ptr<ICell> cell = ws->GetICells()->GetObjectByIndex(new String("A1"));

//Get the string value of cell A1
StringPtr strVal = cell->GetStringValue();

//Print the string value of cell A1
StringPtr cellValue = new String("Cell Value: ");
Console::WriteLine(cellValue->StringAppend(strVal));

//Access cell C4
cell = ws->GetICells()->GetObjectByIndex(new String("C4"));

//Put the string value of cell A1 into C4
intrusive_ptr<String> strValPtr = new String(strVal);
cell->PutValue(strValPtr);

//Save the workbook in csv format
wb->Save(outReadWriteCSV, SaveFormat_CSV);
