具有相似签名的多个webmethods

代码来重现问题：

using System; 
using System.Web; 
using System.Web.Services; 
using System.Web.Services.Protocols; 

namespace TestWebService 
{ 

    public class SomeClass 
    { 
     public int Number; 
    } 

    public class SomeClassRet 
    { 
     public string AString; 
    } 


    [WebService(Namespace = "http://MyNamespace")] 
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] 
    [System.ComponentModel.ToolboxItem(false)] 
    public class MyTestService : System.Web.Services.WebService 
    { 

     [WebMethod] 
     [SoapDocumentMethod("http://MyNamespace/MyMeth", ParameterStyle = SoapParameterStyle.Bare, Use = System.Web.Services.Description.SoapBindingUse.Literal)] 
     public SomeClassRet MyMeth1(SomeClass requestParams) 
     { 
      return null; 
     } 

     [WebMethod] 
     [SoapDocumentMethod("http://AotherNamespace/MyMeth", ParameterStyle = SoapParameterStyle.Bare, Use = System.Web.Services.Description.SoapBindingUse.Literal)] 
     public SomeClassRet MyMeth2(SomeClass requestParams) 
     { 
      return null; 
     } 
    } 
}

我试图做的是有具有相同的签名，除了具有不同SOAPActions 2个webMethods的。上面的代码编译，但试图生成WSDL时，我得到这样一个错误：

Source Error:

上午我试图做一些错误的或不支持？任何解决方法？我无法更改输入或输出参数的名称。目标是除SOAPAction之外具有相同的签名，如果可能的话。

谢谢。

编辑：经过一些进一步的实验后，我决定将复制方法（使用不同的SOAPAction）放在另一个.asmx文件中。

要重载webservice中的方法，您需要提供消息名称属性，或者您可能需要删除关闭一致性检查。

[WebMethod] 
[SoapDocumentMethod("http://MyNamespace/MyMeth",MessageName="MyMeth1" ParameterStyle = SoapParameterStyle.Bare, Use = System.Web.Services.Description.SoapBindingUse.Literal)] 
public SomeClassRet MyMeth1(SomeClass requestParams) 
{ 
return null; 
} 

[WebMethod] 
[SoapDocumentMethod("http://AotherNamespace/MyMeth",MessageName="MyMeth1Overload" ParameterStyle = SoapParameterStyle.Bare, Use = System.Web.Services.Description.SoapBindingUse.Literal)] 
public SomeClassRet MyMeth2(SomeClass requestParams) 
{ 
return null; 
}

而且您可以通过向service.cs文件添加以下行来关闭一致性。

[WebServiceBinding(ConformsTo = WsiProfiles.None)]
