SetElement.SetAttribute("link", "EquipmentInActive.aspx?" + Para);//Error on this line

请帮我.

谢谢

plzzz help me.

thanks

link =''EquipmentActive.aspx?EquipmentID = 21&Section = 2&StartDate = 5/25/2014&EndDate = 6/3/2014&Status = 1&label = 40-303''/>
&是xml中的非法字符.
使用和代替.

link=''EquipmentActive.aspx?EquipmentID=21&Section=2&StartDate=5/25/2014&EndDate=6/3/2014&Status=1&label=40-303'' />
& is an illegal character in the xml.
Use &amp; instead.
