PO.NET webservice client from WSDL
text
Body
copied!<p>I have a WSDL from which I generated the implementation of <a href="http://msdn.microsoft.com/en-us/library/ms576141.aspx" rel="nofollow">ClientBase</a> namely MyService </p> <pre><code> function void updateData(Data data){ BasicHttpBinding binding = new BasicHttpBinding(); // see there is naked username and password. EndpointAddress address = new EndpointAddress("http://qa.farwaha.com/eai_enu/start.swe?SWEExtSource=WebService&SWEExtCmd=Execute&UserName=john&Password=johspassword"); MyService service = new MyService(binding, address); try{ service.update(data); }finally{ service.close(); } } </code></pre> <p>Unfortunately, to call this web service I have to pass User name and password as shown in the code. so, my question is around best practices. </p> <p>Given that its a Winform Application.</p> <ol> <li><p>How memory / CPU intensive is creating MyService object? </p></li> <li><p>If you suggest cashing the service, it will hold on to the EndpointAddress; which intern has a string with Username and Password. Which is not a good idea .. any work arounds? </p></li> <li>If I keep the code as such, service object will be garbage collected .. and there will be no trace of user name or password (as soon as GC runs)</li> </ol> <p><strong>This is a sample code, I have User Object which stores password in SecureString and every time I have to access the password; I get string from SecureString in an instance private method, use it quickly and let it be garbage collected. I believe if I use a method something like above, it will be safe OR safe enough rather than holding on to reference of Service, What do you suggest !!</strong> </p>
