Question

我正在编写一个C＃控制台应用程序，它必须使用公共代理来使用ASP.net webservice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。我需要知道如何实现它。

提前感谢您的建议和意见。

@Pertu感谢输入，我使用相同的方法，但是同一个消费者无法同时调用这两个服务。下面是代码快照

======= Consumer使用的代理来调用webservices ==========

[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，有一段时间在路上...... 这是wsdls

Answer 1

Web服务的美妙之处在于它与客户端无关，或者服务的底层实现是什么。

以您想要的方式构建您的代理或者可以（很多人会说使用WCF）使用您说的相同的合同然后根据需要调用服务;我假设SOAP地址不同，所以请确保参数化（在命令行参数中）...

Answer 2

是的，您可以使用WCF服务＆amp; ASP.NET WebService使用相同的代码。

第1步 - 您需要先更改您的WCF服务以拦截soap标头。使用WCFExtras即可。

第2步 - 使用使用ASP.NET Web Service生成的代理。

如何使用公共参考使用ASP.net Web服务和WCF Web服务
