Вопрос:
Я экспортирую данные C # DataTable в Excel, я получаю ошибку восстановления Excel для столбца boolean datatype. ниже приведен код, который я использую для логического типа данных.
var exception = true;
var cellDataRow = new Cell();
cellDataRow.CellValue = new CellValue(BooleanValue.FromBoolean(exception)); cellDataRow.DataType = CellValues.Boolean;
Ответ №1:
Используйте 0 или 1 для представления false или true соответственно.
