PHP SoapServer返回的字符串值未被.Net客户端接收

I am using the WSDL document automatically generated by Visual Studio 2010 (ie. from the "HelloWorld" application that is created when you create a new web service application in Visual Studio.) But I am needing to develop the web service in PHP, so I am using this WSDL document with PHP SoapServer. I will copy the WSDL document here:

</wsdl:definitions>

My PHP SoapServer code looks like this:

function HelloWorld()
{
   return "Hello world!";
}

$server = new SoapServer( 'helloworld.wsdl' );
$server->addFunction('HelloWorld');
try {
   $server->handle();
}
catch (Exception $e) {
   $server->fault('Sender', $e->getMessage());
}

When I try call this soap service with a .Net client, I am getting an empty string returned. Does anyone know what is going wrong with this simple example?

UPDATE:

This specifically seems to be a problem with communicating with a .Net client from the PHP server. I have tested with a PHP client and I get the message returned by the server in the PHP client. But for some reason the .Net client gets an empty string returned. For the .Net client, I created a simple WinForms application, added a web reference to the php soap server. The web reference gets added correctly and shows the API. I put one button on the form with the following click handle:

private void button1_Click(object sender, EventArgs e)
{
    WebReference.Service1 srv = new WebReference.Service1();
    string result = srv.HelloWorld();
    MessageBox.Show(result);
}

dougu1045 你应该这样做:return[“HelloWorldResult”=>“你的实际回应”];'在你的HelloWorld()函数中。
