 using System.Web.Services.Protocols;

      public string GetUserName() {
       return User.Identity.Name;
      }

Imports System.Web.Services
Imports System.Web.Services.Protocols

Public Class MyUser
    Inherits WebService
        
    <SoapDocumentMethod(Action := "http://www.contoso.com/GetUserName")> _
    Public Function _
        GetUserName() As String
        
        Return User.Identity.Name
    End Function
End Class

Remarks

Typically, the Action property is a URI indicating the intent of the request. However, the SOAP specification places no restrictions on the format of the URI, or any rules about whether the URI is resolvable. The presence and content of the Action property can be used by Web servers, such as firewalls, to appropriately filter SOAP request messages in HTTP.

By default, the .NET Framework version 1.1 publishes the Action property in the soapAction attribute of the soap:operation element for each supported SOAP binding in WSDL documents generated for an XML Web service. For more information, see the SOAP specification on the W3C website.
