Hi,

I am using web services to access sharepoint list,sites and documents. Like: List.asmx,Site.asmx e.t.c.

My question is that:

Do we need to disconnect from sharepoint when using above services? And if yes then How?

Example:

GetSiteCollection(String login, String password, String url)
{

Webs ws = new Webs();                
try
{
 ws.Credentials     = new NetworkCredential(login, password);                    
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
ws.Url              = url + @"/_vti_bin/webs.asmx";
ws.PreAuthenticate  = true;
XmlNode websiteNode = ws.GetWebCollection();
XmlNodeList nodes   = websiteNode.SelectNodes("*"); 

// getting list set of sites

//Now here after this is there any way to disconnect from server? 

}
