У меня есть этот код, который я сейчас использую:
CreateExcelFile.CreateExcelDocument(Start.ToList(), fileFolder + @"ExcelFiles/Start.xlsx");
CreateExcelFile.CreateExcelDocument(DateCPU1.ToList(), fileFolder + @"ExcelFiles/DateCPU1.xlsx");
CreateExcelFile.CreateExcelDocument(Start2.ToList(), fileFolder + @"ExcelFiles/Start2.xlsx");
Подпись для CreateExcelDocument такова:
public static void CreateExcelDocument<T>(List<T> list, string filepath)
Может кто-нибудь сказать мне, как я могу вызвать CreateExcelDocument со списком списков, чтобы я мог вывести всю информацию о моем списке в один документ Excel вместо трех.
Для справки я приведу копию кода, использованного для создания Excel ниже:
