url: http:\\192.168.0.126\C:\temp.xls
本机IP:192.168.0.136
服务器:192.168.0.126
从服务器下载文件
运行时出现"不支持URI格式 "

Answer 1

url= http:\\192.168.0.126\C:\temp.xls 
那里错了啊?
关键

Answer 2

http:\\192.168.0.126\C:\temp.xls 
你在192.168.0.126中有C:这个虚拟目录?

Answer 3

是不是正确的url,很简单,你先在ie地址栏里输一下,看是不是出现下载对话框就知道了

Answer 4

http:\\192.168.0.126\C:\temp.xls 
这种中间加个C:的,,,不知道可不可以,你是要下C盘下的吧,要下载也要是发布了的,放到一个虚拟目录下,如建个虚拟目录,指向文件temp.xls,假设虚拟目录名为tthttp:\\192.168.0.126\C:\temp.xls  中的\\应该换成//吧,?

Answer 5

先在iis里建个虚拟目录,指向c盘,虚拟目录名为test
生成的url就是http://192.168.0.126/test/temp.xls
