上传excel到服务器端，并写入到mssql数据库

经常会有人问这个问题，所以整好一个就放上来！这里只涉及到实现，并不涉及到性能或者可拓展性！

本例子测试成功！（vs2008 +sql2005+office2007）

思路：先上传XLS文件，然后用OleDB连接Excel文件，将Excel数据导入Dataset，再将Dataset数据导入数据库。  
以下是主调入过程

以下是各个主要的函数。  
其中ImportXlsToData是使用OleDb链接Excel文件并将其数据导入Dataset中；  
UpdateXls是上传Xls文件  
AddDatasetToSQL是将Dataset导入数据库

web.config中需要添加数据库连接字符串
