How to: Use SystemService to Find Companies

You can use the SystemService service in a SOAP web service application to retrieve a list of companies available in a specific database. A company name is typically part of the URI when you access a Dynamics NAV web service, and the system service lets you retrieve names of available companies. If you do not specify a company name in a URI, then the default company is used.

In this procedure, you use the SystemService service to retrieve and print a list of companies. You must use Visual Studio 2012 or Visual Studio 2010.

To use the SystemService service to find companies

1. In Visual Studio, on the File menu, point to New, and then choose Project.

2. Expand the Visual C# node, select Windows, and then select Console Application.

   Caution

   Do not double-click or otherwise dismiss the New Project dialog box.

3. Enter FindingCompanies as the Name for the application, and then choose OK.

4. In Solution Explorer, right-click the References node in the project, and then choose Add Service Reference.

5. In the Add Service Reference dialog box, choose the Advanced button, choose the Add Web Reference button, type or paste the URL that you used when checking the WSDL, such as https://localhost:7047/DynamicsNAV/WS/Services, and then choose the green arrow to visit the URL.

6. When the SystemService service is displayed, choose View Service, wait for the service to be displayed, and then choose Add Reference. Rename the Web reference name from localhost to NavSOAPService.

7. On the Program.cs tab, replace the stub code with the following.

   using System;  
   using System.Collections.Generic;  
   using System.Linq;  
   using System.Text;  
   
   namespace FindingCompanies  
   {  
       using System;  
       using NavSOAPService;  
   
       public class Program  
       {  
           static void Main(string[] args)  
           {  
               // Creates instance of service and set credentials.  
               var systemService = new SystemService  
               {  
                   UseDefaultCredentials = true  
               };  
   
               // Loads all companies into an array.  
               var companies = systemService.Companies();  
   
               // Runs through and print all companies.  
               // Also prints company name in encoded form.  
               foreach (string company in companies)  
               {  
                   Console.WriteLine(company);  
                   Console.WriteLine((Uri.EscapeDataString(company)));  
               }  
               Console.ReadLine();  
           }  
       }  
   }  
   
   

8. Save (press Ctrl+F6) and compile (press F6) the FindingCompanies application.

9. Press F5 to run the application in debug mode.

   A list of all companies in the current database is presented in a command session.
