WCF 调用webservice
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

wcf client與webservice通信（-）只修改配置文件而改變服務端問題： 假設有一個大型系統新版本使用wcf 作為服務端，生成wcf client 調用可以調用正常。 那如果當wcf 服務端出現問題或其他的原因我想再用回以前老版本的webservice或是jms server ，但客戶端調用還是通過wcf client 調用。只通過更改配置來實現。
?一、web service項目，添加一個普通service class .代碼如下：

[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配置文件無需更改。運行。記錄服務地址。
?
二、打開路徑C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin：找到svcutil.exe文件。開始菜單-->run --> input cmd --->cd C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin -->回車;
輸入svcutil http://localhost:8080/service/service.asmx,將會在C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin生成一個webservice的代理類。注意：此代理類是wcf client形式的。（在后面只需將這個代理類小作改動，便可用于wcf sevice.）
生成的代理類：

三、添加Console Application,將上面生成的代理類加入項目中，并在Main方法中調用。

???????????//???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},{1})?=?{2}",?value1,?value2,?result);
????????????//?Call?the?Multiply?service?operation.
????????????value1?=?9.00D;
????????????value2?=?81.25D;
????????????result?=?client.Multiply(value1,?value2);
????????????Console.WriteLine("Multiply({0},{1})?=?{2}",?value1,?value2,?result);
????????????//?Call?the?Divide?service?operation.
????????????value1?=?22.00D;
????????????value2?=?7.00D;
????????????result?=?client.Divide(value1,?value2);
????????????Console.WriteLine("Divide({0},{1})?=?{2}",?value1,?value2,?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類的時候會有Out.config同時產生。config里面的內容拷過來即可。

?將webservice運行起來，（也可host到iis 里去。）debug console application.即可看到結果。
回家吃飯了。
細節和要注意的地方在第二節中寫出來。
