Webservice能通过配置文件引用吗？？
现在我引用Webservice都是通过右键-添加Web引用然后输入地址，这样的话要改地址的话就得改程序，能不能通过把webserivce地址放在某个指定的文件里面，然后程序启动的时候读取啊，就像数据库连接那样的。

[解决办法]
wsdl地址可以放到配置文件里嘛，每次改动了地址，只要修改配置地址。

什么版本的vs?
vs2008应该已经把 url放到config文件中了。


[解决办法]
2005应该就自动加到配置文件中了，webservice自然是可以动态改变地址的，可以去设置的，有个属性
[解决办法]
可以的，在webconfig的这个地方：
 <applicationSettings>
   <SendFileTestSender.Properties.Settings>
     <setting name="StateChanged" serializeAs="Xml">
       <value>
         <ArrayOfString xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
           <string>er</string>
         </ArrayOfString>
       </value>
     </setting>
     <setting name="SendFileTestSender_WebReference_DataTransfer" serializeAs="String">
       <!--公司webservice地址-->
       <value>http://8888/888.asmx</value>
     </setting>
   </SendFileTestSender.Properties.Settings>
 </applicationSettings>
