WCF 调用webservice

问题： 假设有一个大型系统新版本使用wcf 作为服务端，生成wcf client 调用可以调用正常。 那如果当wcf 服务端出现问题或其他的原因我想再用回以前老版本的webservice或是jms server ，但客户端调用还是通过wcf client 调用。只通过更改配置来实现。

?一、web service项目，添加一个普通service class .代码如下：

-->Code
[WebService(Namespace="http://Microsoft.ServiceModel.Samples")]
????public?class?CalculatorService?:?System.Web.Services.WebService
????{????????
????????[WebMethod]
????????public?double?Add(double?n1,?double?n2)
????????{
????????????return?n1?+?n2;
????????}
????????[WebMethod]
????????public?double?Subtract(double?n1,?double?n2)
????????{
????????????return?n1?-?n2;
????????}
????????[WebMethod]
????????public?double?Multiply(double?n1,?double?n2)
????????{
????????????return?n1?*?n2;
????????}
????????[WebMethod]
????????public?double?Divide(double?n1,?double?n2)
????????{
????????????return?n1?/?n2;
????????}
????}?

webservice配置文件无需更改。运行。记录服务地址。

?

二、打开路径C:Program FilesMicrosoft SDKsWindowsv6.0Abin：找到svcutil.exe文件。开始菜单-->run --> input cmd --->cd C:Program FilesMicrosoft SDKsWindowsv6.0Abin -->回车;

输入svcutil http://localhost:8080/service/service.asmx,将会在C:Program FilesMicrosoft SDKsWindowsv6.0Abin生成一个webservice的代理类。注意：此代理类是wcf client形式的。（在后面只需将这个代理类小作改动，便可用于wcf sevice.）

生成的代理类：

????????public?double?Divide(double?n1,?double?n2)
????????{
????????????return?base.Channel.Divide(n1,?n2);
????????}
????}

三、添加Console Application,将上面生成的代理类加入项目中，并在Main方法中调用。

???????????//???Service1Client?client?=?new?Service1Client();
????????????//?Call?the?Add?service?operation.
????????????double?value1?=?100.00D;
????????????double?value2?=?15.99D;
????????????
????????????
????????????
????????????
????????????double?result?=?client.Add(value1,?value2);
????????????Console.WriteLine("Add({0},{1})?=?{2}",?value1,?value2,?result);

????????????//?Call?the?Subtract?service?operation.
????????????value1?=?145.00D;
????????????value2?=?76.54D;
????????????result?=?client.Subtract(value1,?value2);
????????????Console.WriteLine("Subtract({0},?result);

????????????//?Call?the?Multiply?service?operation.
????????????value1?=?9.00D;
????????????value2?=?81.25D;
????????????result?=?client.Multiply(value1,?value2);
????????????Console.WriteLine("Multiply({0},?result);

????????????//?Call?the?Divide?service?operation.
????????????value1?=?22.00D;
????????????value2?=?7.00D;
????????????result?=?client.Divide(value1,?value2);
????????????Console.WriteLine("Divide({0},?result);

????????????//Closing?the?client?gracefully?closes?the?connection?and?cleans?up?resources
????????????client.Close();

????????????Console.WriteLine();
????????????Console.WriteLine("Press?<ENTER>?to?terminate?client.");
????????????Console.ReadLine();

添加配置文件：App.config.此配置文件在二步生成代理类的时候会有Out.config同时产生。config里面的内容拷过来即可。

?

?将webservice运行起来，（也可host到iis 里去。）debug console application.即可看到结果。

回家吃饭了。

细节和要注意的地方在第二节中写出来。
