.NET 动态调用WCF

发布时间：2023-09-06 02:05责任编辑：沈小雨关键词：.NET

写在前面

接触WCF还是它在最初诞生之处，一个分布式应用的巨作。从开始接触到现在断断续续，真正使用的项目少之又少，更谈不上深入WCF内部实现机制和原理去研究，最近自己做一个项目时用到了WCF。从这个小项目中我学会了两个地方： 1、利用IIS部署WCF服务，也就是大家接触到的发布SVC文件。2、动态调用WCF接口。

在这个项目中接触WCF时遇到的其实不仅仅是这两个问题，甚至连IIS支持SVC文件也让我折腾了好几把，IIS都重新卸载了两次。我在这篇文章里用两种方式来实现。

如何使用

1、第一种方式比较简单，而且也是大家喜欢的，因为不需要任何配置文件就可解决，只需知道服务契约接口和服务地址就可以调用。

2、使用Invoke的方式，但是需要在调用客户端配置WCF，配置后在Invoke类里封装服务契约接口即可。

客户端调用DEMO

//第一种方式

stringurl ="http://localhost:3000/DoubleService.svc";

IDoubleService proxy = WcfInvokeFactory.CreateServiceByUrl<IDoubleService>(url);

intresult = proxy.Add(1, 3);

//第二种方式<br><br>int result1 = WCFInvoke.Invoke(t => t.Add(1, 3));<br><br>

{

returnCreateServiceByUrl<T>(url,"basicHttpBinding");

}

publicstaticT CreateServiceByUrl<T>(stringurl,stringbing)

{

try

{

if(string.IsNullOrEmpty(url))thrownewNotSupportedException("This url is not Null or Empty!");

EndpointAddress address =newEndpointAddress(url);

Binding binding = CreateBinding(bing);

ChannelFactory<T> factory =newChannelFactory<T>(binding, address);

returnfactory.CreateChannel();

}

catch(Exception ex)

{

thrownewException("创建服务工厂出现异常.");
