WebServiceAttribute.Namespace Property

Definition

Gets or sets the default XML namespace to use for the XML Web service.

public:
 property System::String ^ Namespace { System::String ^ get(); void set(System::String ^ value); };
public string Namespace { get; set; }
member this.Namespace : string with get, set
Public Property Namespace As String

Property Value

The default XML namespace to use for the XML Web service. The default is specified in the DefaultNamespace property.

Examples

The following example sets Namespace to http://www.contoso.com and overrides that namespace for the Action property by adding a SoapDocumentMethodAttribute to the Time XML Web service method.

<%@ WebService Language="C#" class= "ServerVariables"%>
 
 using System;
 using System.Web.Services;
 using System.Web.Services.Protocols;
 
 [ WebService(Description="Server Variables",
 Namespace="http://www.contoso.com/")]
 public class ServerVariables: WebService {
    [ SoapDocumentMethod(Action="http://www.contoso.com/Time")]
    [ WebMethod(Description="Returns the time as stored on the Server",EnableSession=false)]
    public string Time() {
       return Context.Timestamp.TimeOfDay.ToString();
    }
 }
<%@ WebService Language="VB" class= "ServerVariables"%>
 
Imports System
Imports System.Web.Services
Imports System.Web.Services.Protocols

<WebService(Description := "Server Variables", _
    Namespace := "http://www.contoso.com/")> _
Public Class ServerVariables
    Inherits WebService

    <SoapDocumentMethod(Action := "http://www.contoso.com/Time"), _
        WebMethod(Description := "Returns the time as stored on the Server", _
        EnableSession := False)> _
    Public Function Time() As String
        
        Return Context.Timestamp.TimeOfDay.ToString()
    End Function
End Class

Remarks

XML namespaces offer a way to create names in an XML document that are identified by a Uniform Resource Identifier (URI). By using XML namespaces you can uniquely identify elements or attributes in a XML document. The service description for a XML Web service is defined in XML, specifically in Web Services Description Language (WSDL).

Within the Service Description for an XML Web service, Namespace is used as the default namespace for XML elements directly pertaining to the XML Web service. For example, the name of the XML Web service and its XML Web service methods pertain to the namespace specified in the Namespace property. Elements that are specific to WSDL pertain to the http://schemas.xmlsoap.org/wsdl/ namespace.

For XML Web service clients using SOAP to call an XML Web service, you can optionally add the SoapDocumentMethodAttribute or SoapRpcMethodAttribute to call an XML Web service method. If the client is calling an XML Web service created using ASP.NET, the RequestNamespace, ResponseNamespace and Action properties are all derived from the Namespace property by default. For instance, given an XML Web service method name of Time and a Namespace property of http://www.contoso.com/, the Action property is http://www.contoso.com/Time by default. To change the default settings for RequestNamespace, ResponseNamespace, and Action for an XML Web service method, you can add a SoapDocumentMethodAttribute to the XML Web service method.

Note

An XML namespace is different from the namespace the class resides in, in terms of the Windows SDK. To specify the namespace for the class, see Namespace Keywords if you writing in C#.
