用OLEDB进行Excel文件数据读取并返DataSet数据集其几点需要注意:
1.连接字符串参数IMEX 值:
0 is Export mode
1 is Import mode
2 is Linked mode (full update capabilities)
IMEX3值:IMEX=2 EXCEL文档同含字符型数字型比第C列3值2数值型 1231字符型 ABC导入
页面报错库显示数值型123字符型ABC则呈现空值IMEX=1述情况发库确呈现 123 ABC.
2.参数HDR值:销判
HDR=Yes代表第行标题做数据使用 用HDR=NO则表示做旦第行标题做数据使用系统默认YES
3.参数Excel 8.0
于Excel 97版本都用Excel 8.0

#region 获取excel dataset ,即名excel_ds
string excelFilePath = openFileDialog1.FileName;//弹文件选取窗口获取EXCEL文件纯斗扰路径
string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + excelFilePath + ";Extended Properties=\"Excel 8.0;HDR=YES;IMEX=1\"";
OleDbConnection Oleconn = new OleDbConnection(strConn);
