修改客户端配置文件:

在客户端的配置文件中添加<appSettings>,方便获取更改.

        /// <summary>
        /// 更改配置文件
        /// </summary>
        /// <param name="serverIp"></param>
        public static void ChanageConfig(string serverIp) 
        { 
            Configuration config = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath); 
            ConfigurationSectionGroup sct = config.SectionGroups["system.serviceModel"]; 
            ServiceModelSectionGroup serviceModelSectionGroup = sct as ServiceModelSectionGroup; 
            ClientSection clientSection = serviceModelSectionGroup.Client; 
            
            foreach (ChannelEndpointElement item in clientSection.Endpoints)
            {
                string[] str = item.Address.ToString().Split('/');
                string pattern ="";
                for (int i = 0; i < str.Length-2; i++)
                    pattern += str[i] + '/';
                string address = item.Address.ToString();
                string replacement = string.Format("{0}", serverIp);
                address = Regex.Replace(address, pattern, replacement); 
                item.Address = new Uri(address);
            } 
            config.Save(ConfigurationSaveMode.Modified); 
            ConfigurationManager.RefreshSection("system.serviceModel");
        }

修改服务端配置文件:

在服务端的配置文件中也添加<appSettings>,方便获取更改.

        /// <summary>
        /// 更改服务配置文件
        /// </summary>
        /// <param name="serverIp"></param>
        public static void ChangeServiceConfig(string serverIp)
        {
            Configuration config = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath);
            ConfigurationSectionGroup sct = config.SectionGroups["system.serviceModel"];
            ServiceModelSectionGroup serviceModelSectionGroup = sct as ServiceModelSectionGroup;
            ServicesSection serviceSection = serviceModelSectionGroup.Services;

            foreach (ServiceElement item in serviceSection.Services)
            {
                string address = item.Host.BaseAddresses[0].BaseAddress;
                string[] str = address.Split('/');
                string pattern = "";
                for (int i = 0; i < str.Length - 2; i++)
                    pattern += str[i] + '/';
                string replacement = string.Format("{0}", serverIp);
                address = Regex.Replace(address, pattern, replacement);
                item.Host.BaseAddresses[0].BaseAddress = address;
            }
            config.Save(ConfigurationSaveMode.Modified);
            ConfigurationManager.RefreshSection("system.serviceModel");
        }

WCF中容易出现的错误:在服务“Service1”实现的协定列表中找不到协定名称

出错的原因有两个:

1. 看契约是否写对, 这个一般不会写错

2.看配置文件:service name="空间名+服务名称"    endpoint contract="空间名+契约名称"

(这里有个小细节要注意, ""中不能出现空格,否则依然报错)
