服务器无法处理服务器不承认HTTP头SOAPAction的价值：

这是例外，当我试图来调用Web服务的方法流：

An exception flows when I was trying to call a method on web service:

System.Web.Services.Protocols.SoapException: Server did not recognize the value of HTTP Header SOAPAction: http://localhost:53460/3Development/MyWebService.asmx/GetBasePath.
   at System.Web.Services.Protocols.Soap11ServerProtocolHelper.RouteRequest()
   at System.Web.Services.Protocols.SoapServerProtocol.RouteRequest(SoapServerMessage message)
   at System.Web.Services.Protocols.SoapServerProtocol.Initialize()
   at System.Web.Services.Protocols.ServerProtocolFactory.Create(Type type, HttpContext context, HttpRequest request, HttpResponse response, Boolean& abortProcessing)

Web服务的命名空间：

The web service's namespace:

[WebService(Namespace = "http://internaltest.temp.us/MyWebService.asmx")]

我做了一些研究，发现了这个异常流入，因为在这个项目中引用的Web服务的命名空间是从服务器Web服务的命名空间的不同，但我试着删除Web引用，并在项目重新添加，但结果还是一样。

I did some research and found out that this exception flows because the web service's namespace referenced in the project was different from the server web service's namespace, but I've tried removing web reference and add it again in the project, but the result was still the same.

我的情况是类似以下文章：

My situation was similar to the below article:

http://bluebones.net/2003/07/server-did-not-recognize-http-header-soapaction/

从文章：

所以基本上Web服务从 http://foo.com/servicename 感动
  到 http://bar.com/servicename 但Web服务的空间
  留校 http://foo.com/servicename 因为没有人改变了它。

So basically the web service was moved from http://foo.com/servicename to http://bar.com/servicename but the "namespace" of the web service stayed as http://foo.com/servicename because no one changed it.

问题是：

如何改变Web引用的命名空间？

How to change the namespace of the web reference?
