WCF 动态调用（动态创建实例接口）

 

 

wcf binding string url bing null

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：

 

[csharp]  view plain copy

 

1. using System;  
2. using System.Collections.Generic;  
3. using System.Linq;  
4. using System.Web;  
5. using System.ServiceModel;  
6. using System.ServiceModel.Channels;  
7.   
8.   
9. /// <summary>  
10. /// 动态调用WCF的工具类库  
11. /// </summary>  
12. public class InvokeContext  
13. {  
14.  
15.     #region Wcf服务工厂  
16.     public static T CreateWCFServiceByURL<T>(string url)  
17.     {  
18.         return CreateWCFServiceByURL<T>(url, "wsHttpBinding");  
19.     }  
20.   
21.   
22.     public static T CreateWCFServiceByURL<T>(string url, string bing)  
23.     {  
24.         if (string.IsNullOrEmpty(url)) throw new NotSupportedException("this url isn`t Null or Empty!");  
25.         EndpointAddress address = new EndpointAddress(url);  //终结点地址
26.         Binding binding = CreateBinding(bing);  返回一个包含在当前绑定中的已排序的绑定元素集合
27.         ChannelFactory<T> factory = new ChannelFactory<T>(binding, address);  //由通道工厂生成的通道类型。此类型必须
28. //为 IOutputChannel 或 IRequestChannel。
29.         return factory.CreateChannel();  //创建 TChannel 类型（类的泛型参数）的通道。
30.     }  
31.     #endregion  
32.

IWCFserver 是通过 

svcutil.exe http://localhost:8034/WCFserver.svc?wsdl

 自动生成的。

[csharp]  view plain copy

 

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