如何使用通用参考使用 ASP.net Web 服务和 WCF Web 服务

Question

我正在编写一个 C# 控制台应用程序，该应用程序必须使用通用代理来使用 ASP.net Web 服务和 WCF 服务。 WCF 和 ASP.net Web 服务将实现相同的数据和服务契约以及相同的命名空间。 我需要知道它是如何实现的。

提前感谢您的建议和意见。

@Pertu 感谢您的输入，我正在使用相同的方法，但是同一消费者无法同时调用这两种服务。下面是代码截图

======= Consumer 用来调用 web 服务的代理==========

[System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl", "4.0.30319.1")]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Web.Services.WebServiceBindingAttribute(Name="BaseServiceSoap", 
Namespace="http://tempuri.org/")]

public partial class BaseService : System.Web.Services.Protocols.SoapHttpClientProtocol 
{

private System.Threading.SendOrPostCallback GetWeightOperationCompleted;

/// <remarks/>
public BaseService()
{
    this.Url = "http://localhost:53899/BaseService.asmx";
}
......

======== Consumer Code
//Below call to ASP.NEt webservice succeeds 

BaseService typeACalculator = new BaseService();
typeACalculator.Url = "http://localhost:54106/TypeA.asmx";
Console.WriteLine("Article for type A weighs: " +
    typeACalculator.GetWeight(articleForCalcA).ToString());

//Below call to WCF fails

BaseService WCFCalculator = new BaseService();

WCFCalculator.Url = "http://localhost:52224/TypeWCF35Calc.svc";
Console.WriteLine("Article for type WCF weighs: " +
    WCFCalculator.GetWeight(articleForCalcB).ToString());
Console.ReadKey();

======== Contract in WCF===============

 [ServiceContract]
 public interface IBaseServiceSoap 
 {
   [OperationContract]
    double GetWeight(Article article);
 }

====== Contract in ASP.NEt webservice================
/// <remarks/>


  [System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl", "4.0.30319.1")]
  [System.Web.Services.WebServiceBindingAttribute(Name="BaseServiceSoap", 
    Namespace="http://tempuri.org/")]
  public interface IBaseServiceSoap 
  {

   /// <remarks/>
   [System.Web.Services.WebMethodAttribute()]
   [System.Web.Services.Protocols.SoapDocumentMethodAttribute  
   ("http://tempuri.org/GetWeight",     
   RequestNamespace="http://tempuri.org/", ResponseNamespace="http://tempuri.org/",  
   Use=System.Web.Services.Description.SoapBindingUse.Literal, 
   ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]

   double GetWeight(Article article);
  }    

嗯，已经在路上一段时间了.... 这是wsdls

Answer 1

Web 服务的优点在于，客户端是什么或服务的底层实现是什么并不重要。

使用您所说的相同合同以您想要或可以的任何方式（许多人会说使用 WCF）构建您的代理，然后根据需要调用服务；我假设 SOAP 地址不同，因此请确保将其参数化（在命令行参数中）...

Answer 2

是的，您可以使用相同的代码使用 WCF 服务和 ASP.NET WebService。

步骤 1- 你需要先改变你的 WCF 服务来拦截肥皂头。使用WCFExtras。

步骤 2- 使用使用 ASP.NET Web 服务生成的代理。
