Microsoft Visual Studio includes a wizard that generates a Web Service client proxy that you can use to call Web Service methods. The wizard is launched
               via 
               . 
               
            
 
            
            
               -  
                  Type the URL of your Web Service into the top text box, for example, 
                     http://demo.borland.com/BorlandSampleService/BorlandSampleService.asmx?WSDL, and click 
                     Enter. 
                      
                   The 
                  Add Web Reference button is enabled when the wizard loads the WSDL document from the specified URL. 
                   
                  
               
-  
                   Click 
                     Add Web Reference. 
                      
                   The wizard generates a proxy class in a namespace that is the reverse of the name of the Web server that hosts the service
                  (for example, 
                  demo.host.com becomes 
                  com.host.demo). 
                   
                  
               
-  
                  Explore objects to see which classes have been generated. Each Web Service, and all complex data types used by the Web Service
                     methods, are represented as classes. 
                      
                   In the generated proxy code, the proxy class takes its name from the Web Service. The namespace of the class is the reverse
                  of the name of the Web server that hosts the service. All files that are generated by the 
                  Add Web Reference wizard are displayed on the 
                  Solution Explorer tab. 
                   
                    
                  
                  注: The 
                     Show All Files option must be activated to display all generated files.
