SoapRpcMethodAttribute.Binding Property

Definition

Namespace:

System.Web.Services.Protocols

Assembly:

System.Web.Services.dll

Gets or sets the binding that an XML Web service method implements an operation for.

public:
 property System::String ^ Binding { System::String ^ get(); void set(System::String ^ value); };

public string Binding { get; set; }

member this.Binding : string with get, set

Public Property Binding As String

Property Value

String

The binding an XML Web service method implements an operation for. The default is the name of the XML Web service with "Soap" appended.

Examples

The following code example demonstrates how to implement multiple bindings within an XML Web service.

<%@ WebService Language="C#" class="BindingSample" %>
 using System;
 using System.Web.Services;
 using System.Web.Services.Protocols;

 // Binding is defined in this XML Web service and uses the default namespace.
 [ WebServiceBinding(Name="LocalBinding")]
 // Binding is defined in this XML Web service, but not a part of the default namespace.
 [ WebServiceBinding(Name="LocalBindingNonDefaultNamespace", Namespace="http://www.contoso.com/MyBinding")]
 // Binding is defined on a remote server, but this XML Web service implements at least one operation in that binding.
 [ WebServiceBinding(Name="RemoteBinding",Namespace="http://www.contoso.com/MyBinding",Location="http://www.contoso.com/MySevice.asmx?wsdl")]
 public class BindingSample  {

      [ SoapRpcMethod(Binding="LocalBinding")]
      [ WebMethod ]
      public string LocalBindingMethod() {
            return "Member of binding defined in this XML Web service and member of the default namespace";
      }
      [ SoapRpcMethodAttribute(Binding="LocalBindingNonDefaultNamespace")] 
      [ WebMethod ]
      public string LocalBindingNonDefaultNamespaceMethod() {
            return "Member of binding defined in this XML Web service, but a part of a different namespace";
      }

     [ SoapRpcMethodAttribute(Binding="RemoteBinding")] 
     [ WebMethod ]
      public string RemoteBindingMethod() {
            return "Member of a binding defined on another server";
      }

      [ WebMethod  ]
      public string DefaultBindingMethod() {
            return "Member of the default binding";
      }
 
 }

<%@ WebService Language="VB" class="BindingSample" %>
 Imports System.Web.Services
 Imports System.Web.Services.Protocols

 ' Three bindings are defined
   < WebServiceBinding(Name:="LocalBinding"), _
   WebServiceBinding(Name:="LocalBindingNonDefaultNamespace",Namespace:="http://www.contoso.com/MyBinding"), _
   WebServiceBinding(Name:="RemoteBinding",Namespace:="http://www.contoso.com/MyBinding",Location:="http://www.contoso.com/MySevice.asmx?wsdl")> _
 Public class BindingSample  

      < SoapRpcMethod(Binding:="LocalBinding"), WebMethod > _
      Public Function LocalBindingMethod() As String
            Return "Member of binding defined in this XML Web service and member of the default namespace"
          End Function

          < SoapRpcMethodAttribute(Binding:="LocalBindingNonDefaultNamespace"), WebMethod > _
      Public Function LocalBindingNonDefaultNamespaceMethod() As String
        Return "Member of binding defined in this XML Web service, but a part of a different namespace"
      End Function
    
          < SoapRpcMethodAttribute(Binding:="RemoteBinding"), WebMethod > _
      Public Function RemoteBindingMethod() As String
        Return "Member of a binding defined on another server"
      End Function

          < WebMethod > _
      Public Function DefaultBindingMethod() As String
        Return "Member of the default binding"
      End Function
End Class

Remarks

A binding, as defined by Web Services Description Language (WSDL), is similar to an interface in that it defines a concrete set of operations. With respect to ASP.NET, each XML Web service method is an operation within a binding. XML Web service methods are members of the default binding for an XML Web service or a binding specified within a WebServiceBindingAttribute applied to an XML Web service. An XML Web service can implement multiple bindings, if multiple WebServiceBindingAttribute attributes are applied to an XML Web service.

Once one or more WebServiceBindingAttribute attributes are applied to an XML Web service, a SoapDocumentMethodAttribute or SoapRpcMethodAttribute can be applied to individual XML Web service methods to indicate the binding operation implemented by a particular XML Web service method. Set the Binding property of SoapDocumentMethodAttribute or SoapRpcMethodAttribute to specify the binding an XML Web service method implements an operation for. Only one SoapDocumentMethodAttribute or SoapRpcMethodAttribute can be applied to an XML Web service method. Therefore, an XML Web service method can only implement an operation for one binding.
