我正在使用wsdl，它会自动在xml中添加额外的元素。为了使其符合不使用这些元素的外部Web服务。见下图： http://img406.imageshack.us/img406/1307/differencese.png 左=红色元素需要删除 - 右=我需要它输出
我附上了创建信封和有效负载的代码。
Dim content As myProxy.Content = New myProxy.Content
Dim inputguid As String = Guid.NewGuid.ToString
Dim service As myProxy.WebService = New myProxy.WebService
Dim str As New System.Xml.XmlDocument
Dim payload As myProxy.Payload = New myProxy.Payload
'payload
str.LoadXml(xmlstr)
'manifest
service.payloadManifest = New myProxy.PayloadManifest
service.payloadManifest.manifest = New myProxy.Manifest() {New myProxy.Manifest}
service.payloadManifest.manifest(0).element = "GetVehicleServiceHistory"
service.payloadManifest.manifest(0).namespaceURI = ""
service.payloadManifest.manifest(0).contentID = "Content0"
service.payloadManifest.manifest(0).version = "2.01"
service.SoapVersion = SoapProtocolVersion.Soap11
service.UserAgent = "Jakarta Commons-HttpClient/3.1"
Dim usertoken As New Microsoft.Web.Services3.Security.Tokens.UsernameToken("userid", "password", Microsoft.Web.Services3.Security.Tokens.PasswordOption.SendPlainText)
service.RequestSoapContext.Security.Tokens.Add(usertoken)
service.RequestSoapContext.Security.MustUnderstand = False
payload.content = New myProxy.Content() {content}
ReDim Preserve payload.content(0)
payload.content(0).Any = str.DocumentElement
payload.content(0).id = "Content0"
service.Url = "http://localhost:8080"
service.ProcessMessage(payload)
非常感谢任何帮助。

你可以写一个SoapExtension。我过去已经这样做了，以清除SOAP响应中的非法字符，但您也可以使用它来修改您的请求。基本上它会在发送之前拦截SOAP包，或者在收到它之前拦截它，但在.Net反序列化它之前。
StefanGoßner有一篇旧帖子，其中解释了how build a SoapExtension。您可以将代码放在ProcessOutput方法中。
缺点是您正在将SOAP消息解析为文本，但当然可以在XDocument或XmlDocument中加载它，如果效果更好的话。但是你之后也将它传递给了文本。
如果您正在使用WCF，那么请查看Intercept messages in a WCF Client，因为您必须为SOAP拦截实现IClientMessageInspector。
希望这会对你有所帮助。

Dim content As blah.Content = New blah.Content
Dim inputguid As String = Guid.NewGuid.ToString
Dim service As blah.WebService = New blah.WebService
Dim str As New System.Xml.XmlDocument
Dim payload As blah.Payload = New blah.Payload
'payload
str.LoadXml(xmlstr)
'manifest
service.payloadManifest = New blah.PayloadManifest
service.payloadManifest.manifest = New blah.Manifest() {New blah.Manifest}
service.payloadManifest.manifest(0).element = "GetVehicleServiceHistory"
service.payloadManifest.manifest(0).namespaceURI = ""
service.payloadManifest.manifest(0).contentID = "Content0"
service.payloadManifest.manifest(0).version = "2.01"
service.SoapVersion = SoapProtocolVersion.Soap11
service.UserAgent = "Jakarta Commons-HttpClient/3.1"
payload.content = New blah.Content() {content}
ReDim Preserve payload.content(0)
payload.content(0).Any = str.DocumentElement
payload.content(0).id = "Content0"
service.ProcessMessage(payload)
注意到我已经删除了WSE编码： -
在网络参考reference.vb中，我在pcublic sub new中添加了以下代码 -
Dim policy As New Policy()
policy.Assertions.Add(New MyAssertion())
Me.SetPolicy(policy)
然后
Public Class MyPolicy
Inherits SoapFilter
Public Overrides Function ProcessMessage(ByVal envelope As SoapEnvelope) As SoapFilterResult
'creating the <wsse:Security> element in the outgoing message
Dim securityNode As XmlNode = envelope.CreateNode(XmlNodeType.Element, "wsse:Security", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd")
Dim securityAttr As XmlAttribute = envelope.CreateAttribute("soap:mustunderstand")
securityAttr.Value = "1"

usernameTokenNode.AppendChild(userNameNode)
