原因是在web.config 文件中多次引用了“添加外部引用”
<system.serviceModel> <bindings> <basicHttpBinding> <binding name="WebServiceSoap" /> <binding name="WebServiceSoap1" /> </basicHttpBinding> </bindings> <client> <endpoint address="http://localhost:8054/WebService.asmx" binding="basicHttpBinding" bindingConfiguration="WebServiceSoap" contract="ServiceReference.WebServiceSoap" name="WebServiceSoap" /> <endpoint address="http://localhost:8054/WebService.asmx" binding="basicHttpBinding" bindingConfiguration="WebServiceSoap1" contract="ServiceReference.WebServiceSoap" name="WebServiceSoap1" /> </client> </system.serviceModel>
所以删掉一个节点既可(如查引用的是WebServiceSoap,删掉WebServiceSoap1的有关节点,反之~)
也可以在页面引用的时候指定bindingConfiguration名字:
如:ServiceReference.WebServiceSoap web = new WebServiceSoapClient("WebServiceSoap");
