很多时候，服务地址都不止一个的，这个时候就要动态去配置地址。配置Web.config，很麻烦

下面就看看怎样实现动态调用WCF。

首先看看动态创建服务对象的代码：

 

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.ServiceModel;using System.ServiceModel.Channels;/// 
/// 动态调用WCF的工具类库/// 
public class InvokeContext{    #region Wcf服务工厂    public static T CreateWCFServiceByURL
     
      (string url)    {        return CreateWCFServiceByURL
      
       (url, "wsHttpBinding");    }    public static T CreateWCFServiceByURL
       
        (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
        
          factory = new ChannelFactory
         
          (binding, address);        return factory.CreateChannel();    }    #endregion    #region 创建传输协议    /// 
          
 /// 创建传输协议 /// 
    /// 
          传输协议名称    /// 
              private static Binding CreateBinding(string binding)    {        Binding bindinginstance = null;        if (binding.ToLower() == "basichttpbinding")        {            BasicHttpBinding ws = new BasicHttpBinding();            ws.MaxBufferSize = 2147483647;            ws.MaxBufferPoolSize = 2147483647;            ws.MaxReceivedMessageSize = 2147483647;            ws.ReaderQuotas.MaxStringContentLength = 2147483647;            ws.CloseTimeout = new TimeSpan(0, 10, 0);            ws.OpenTimeout = new TimeSpan(0, 10, 0);            ws.ReceiveTimeout = new TimeSpan(0, 10, 0);            ws.SendTimeout = new TimeSpan(0, 10, 0);            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}
         
        
       
      
     

IWCFserver 是通过 

svcutil.exe

 自动生成的。

IWCFserver dpser = InvokeContext.CreateWCFServiceByURL
     
      (Public.getXmlElementValue("LocalDpPathologySliceServ"), "basicHttpBinding");
