FileStream fileStream = new FileStream(@FileName, FileMode.Open, FileAccess.Read);
FileStream fileStream2;
if (FileName.IndexOf(".xlsx") > 0) // 2007版本
{
workbook1 = new XSSFWorkbook(fileStream); //xlsx数据读入workbook
}
else if (FileName.IndexOf(".xls") > 0) // 2003版本
{
workbook1 = new HSSFWorkbook(fileStream); //xls数据读入workbook
}
ISheet sheet = workbook1.GetSheetAt(0); //获取第一个工作表
IRow row = sheet.GetRow(0);
row.Height = 20 * 20;
using (fileStream2 = File.OpenWrite(FileName))
{
workbook1.Write(fileStream2);//向打开的这个xls文件中写入数据
}
fileStream.Close();
workbook1.Close();
fileStream2.Close();
fileStream2.Dispose();
用fileStream不知道为啥就是写不上？？修改FileAccess也不行，只能再定义一个这种笨办法了
