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：
复制代码 代码如下:
create table IntoExcel
(
Tid int identity(1,1) primary key,
Tname varchar(50),
Tage int,
Taddress varchar(200),
)
(
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。
希望本文所述对大家的asp.net程序设计有所帮助。
