Using SystemService to Find Companies

  • 项目

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 Business Central 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 in Visual Studio.

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/BC130/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 BCSOAPService;  

    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 (select Ctrl+F6) and compile (select F6) the FindingCompanies application.

  9. Select F5to run the application in debug mode.

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