asp.net实现 EXCEL数据导入到数据库功能
注意：EXCEL中的第一行不能导入。
下面是源码：

Data Source=" + savePath + "; // 数据库地址
Extended Properties='Excel 8.0; // 连接的是Excel8.0
HDR=YES;// 有两个值:YES/ NO, 这2个值，说了你是否能直接读列名，NO，只可以读下标
IMEX=1;//解决数字与字符混合时,识别不正常的情况.
这个读入数据库的方式不是最佳的，应该用office组件
select * from [Sheet1$] //引用EXCLE文件中sheet1工作表的内容
OleDB控件用的是OleDb的驱动程序，可以访问各种数据库
数据库中的字段：
[sql]
create table IntoExcel
(
Tid int identity(1,1) primary key,
Tname varchar(50),
Tage int,
Taddress varchar(200),
)
SQL控件用的是专用的驱动程序，能高效的访问SQL Server数据库
SQLConnection只能访问SQL Server，而OleDbConnection则可以访问所有数据库。
如果只是访问SQL Server的话，SQL比OleDb更快。
