导入xls/xlsx到DataTable:

HSSFWorkbook: http://www.cnblogs.com/songrun/p/3547738.html

OLEDB:

HDR=Yes，这代表第一行是标题，不做为数据使用；IMEX ( IMport EXport mode )设置
　　IMEX 有三种模式：
　　0 is Export mode
　　1 is Import mode
　　2 is Linked mode (full update capabilities)
　　我这里特别要说明的就是 IMEX 参数了，因为不同的模式代表著不同的读写行为：
　　当 IMEX=0 时为“汇出模式”，这个模式开启的 Excel 档案只能用来做“写入”用途。
　　当 IMEX=1 时为“汇入模式”，这个模式开启的 Excel 档案只能用来做“读取”用途。
　　当 IMEX=2 时为“连结模式”，这个模式开启的 Excel 档案可同时支援“读取”与“写入”用途。
