我如何调用WCF服务

本文介绍了我如何调用WCF服务的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 每一个 i有一个wcf服务（Chat_Server） 我用命令做了一个web.config和callback类：Hi every onei have a wcf service (Chat_Server)and i made a web.config and callback class with command :svcutil.exe http://localhost:1462/Service_Chat.svc?wsdl 这是我的配置：this is my config :<?xml version="1.0" encoding="utf-8"?><configuration> <system.serviceModel> <bindings> <wsDualHttpBinding> <binding name="WSDualHttpBinding_IService_Chat"> <reliableSession inactivityTimeout="00:01:00" /> <security mode="None" /> </binding> </wsDualHttpBinding> </bindings> <client> <endpoint address="http://localhost:1462/Service_Chat.svc" binding="wsDualHttpBinding" bindingConfiguration="WSDualHttpBinding_IService_Chat" contract="IService_Chat" name="WSDualHttpBinding_IService_Chat" /> </client> </system.serviceModel></configuration> 这是我的班级（Service_ChatClient）名称：and this is my class with (Service_ChatClient) name :'------------------------------------------------------------------------------' <auto-generated>' This code was generated by a tool.'
