动态调用WCF服务

动态调用WCF服务，只需要提供*.svc地址，

1:命名空间：

using System.ServiceModel.Channels;
using System.ServiceModel;

2:创建访问类InvokeContext

public class InvokeContext
    {

#region Wcf服务工厂
        public static T CreateWCFServiceByURL<T>(string url)
        {
            return CreateWCFServiceByURL<T>(url, "wsHttpBinding");
        }
        public static T CreateWCFServiceByURL<T>(string url,string bing)
        {
            if (string.IsNullOrEmpty(url)) throw new NotSupportedException("this url isn`t Null or Empty!");
            EndpointAddress address = new EndpointAddress(url);
            Binding binding = CreateBinding(bing);
            ChannelFactory<T> factory = new ChannelFactory<T>(binding, address);
            return factory.CreateChannel();
        }
        #endregion

        #region 创建传输协议
        /// <summary>
        /// 创建传输协议
        /// </summary>
        /// <param name="binding">传输协议名称</param>
        /// <returns></returns>
        private static Binding CreateBinding(string binding)
        {
            Binding bindinginstance = null;
            if (binding.ToLower() == "basichttpbinding")
            {
                BasicHttpBinding ws = new BasicHttpBinding();
                ws.MaxReceivedMessageSize = 65535000;
                bindinginstance = ws;
            }
            else if (binding.ToLower() == "netnamedpipebinding")
            {
                NetNamedPipeBinding ws = new NetNamedPipeBinding();
                ws.MaxReceivedMessageSize = 65535000;
                bindinginstance = ws;
            }
            else if (binding.ToLower() == "netpeertcpbinding")
            {
                NetPeerTcpBinding ws = new NetPeerTcpBinding();
                ws.MaxReceivedMessageSize = 65535000;
                bindinginstance = ws;
            }
            else if (binding.ToLower() == "nettcpbinding")
            {
                NetTcpBinding ws = new NetTcpBinding();
                ws.MaxReceivedMessageSize = 65535000;
                ws.Security.Mode = SecurityMode.None;
                bindinginstance = ws;
            }
            else if (binding.ToLower() == "wsdualhttpbinding")
            {
                WSDualHttpBinding ws = new WSDualHttpBinding();
                ws.MaxReceivedMessageSize = 65535000;

                bindinginstance = ws;
            }
            else if (binding.ToLower() == "webhttpbinding")
            {
                WebHttpBinding ws = new WebHttpBinding();
                ws.MaxReceivedMessageSize = 65535000;
                bindinginstance = ws;
            }
            else if (binding.ToLower() == "wsfederationhttpbinding")
            {
                WSFederationHttpBinding ws = new WSFederationHttpBinding();
                ws.MaxReceivedMessageSize = 65535000;
                bindinginstance = ws;
            }
            else if (binding.ToLower() == "wshttpbinding")
            {
                WSHttpBinding ws = new WSHttpBinding(SecurityMode.None);
                ws.MaxReceivedMessageSize = 65535000;
                ws.Security.Message.ClientCredentialType = System.ServiceModel.MessageCredentialType.Windows;
                ws.Security.Transport.ClientCredentialType = System.ServiceModel.HttpClientCredentialType.Windows;
                bindinginstance = ws;
            }
            return bindinginstance;

        }
        #endregion

}

3.T为调用的接口类型，就是WCF返回的类的实例，由于我的WCF是基于接口的，所以加了一个接品类型判断，调用时直接写：Interface iface = InvokeContext.CreateWCFServiceByURL<Interface>(url);
