我这里错在哪了?来帮我看看!!!
是将Excel导入到数据库的


private   void   Button1_Click(object   sender,   System.EventArgs   e)
{
SqlConnection   con=new   SqlConnection( "server=.;database=ExcelToSql;uid=sa;pwd=; ");
con.Open();
SqlCommand   cmd=new   SqlCommand( "insert   into   test   select   *   from   OPENROWSET( 'MICROSOFT.JET.OLEDB.4.0 ', 'Excel   5.0;HDR=YES;DATABASE=c:\test.xls ',sheet1$) ",con);
cmd.ExecuteReader();
}


应该怎么改才对??????谢谢!!!

cmd.ExecuteNonQuery();
