本文实例讲述了asp.net中EXCEL数据导入到数据库的方法。分享给大家供大家参考。具体分析如下：
excel是办公中非常常用的一个办公表格了，但我们在开发中通常会需要直接把excel数据快速导入到数据库中了，这里整理了一个asp.net中EXCEL数据导入到数据库的例子供各位参考学习。
注意：EXCEL中的第一行不能导入。
下面是源码：IntoExcel.aspx：
复制代码代码如下:

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。
