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://10.29.68.32/WebService.asmx" binding="basicHttpBinding"
bindingConfiguration="WebServiceSoap" contract="ServiceReference.WebServiceSoap"
name="WebServiceSoap" />
<endpoint address="http://10.29.68.32/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");
