摘要：string[] sss = Directory.GetFiles("D:\\价格导入", "*.mp3", SearchOption.AllDirectories) // 获取目录下.mp…
string[] sss = Directory.GetFiles("D:\\价格导入", "*.mp3", SearchOption.AllDirectories) // 获取目录下.mp3格式文件 包含子目录
//遍历子目录包含.xlsx和.xls的
var flist = Directory.GetFiles("D:\\价格导入", "*.*", SearchOption.AllDirectories).Where(s => s.EndsWith(".xlsx") || s.EndsWith(".xls"));
//List<FileInfo> flist = getFile("D:\\KSM价格导入", ".xlsx.xls");
foreach (string filepath in flist)
{
Workbook workbook = new Workbook(filepath);
Worksheet worksheet = workbook.Worksheets[0];
DataTable dt = worksheet.Cells.ExportDataTable(0, 0, worksheet.Cells.MaxRow + 1, worksheet.Cells.MaxColumn + 1);
mainThreadSynContext.Post(new SendOrPostCallback(OnConnected), "");//通知主线程
