この方法で OPC UA サーバーを起動しようとしました: http://documentation.unified-automation.com/uasdkdotnet/2.1.0/html/L3ServerTutGSLess01.html

ApplicationLicenseManager.AddProcessLicenses(Assembly.GetExecutingAssembly(), "License.lic");
MyServerManager server = new MyServerManager();
ApplicationInstance.Default.Start(server, null, server); //Start the server

次のエラーが表示されApplicationInstance.Default.Start(server, null, server)" ます: System.NullReferenceException: オブジェクト参照がオブジェクト インスタンスに設定されていません。UnifiedAutomation.UaServer.ServerSettings..ctor (ApplicationInstance アプリケーション) で UnifiedAutomation.UaServer.ServerManager.OnServerStarting (ApplicationInstance アプリケーション) で UnifiedAutomation.UaBase.ServerBase.Start (ApplicationInstance アプリケーション) で UnifiedAutomation.UaServer.ServerManager.Start (ApplicationInstance アプリケーション) でUnifiedAutomation.UaBase.ApplicationInstance.Start (ServerBase サーバー、WaitCallback コールバック、オブジェクト userData) は、TapakoServerStarter.cs: 行の VeitsServer.TapakoServerStarter.StartAkomiServer (IDevice testDeviceToLink) にあります。39 at Implementationstests.OpcUaServerTest.ServerShouldRun() in OpcUaServerTest.cs: 行 44

から内部的に開始された場合、同じコードは正常に機能しMain()ます。しかし、同じプロジェクト マップ (テスト プロジェクトなど) 内の外部プロジェクトで OpcUaServerStarter を呼び出そうとするとすぐに、NullReferenceException が表示されます。

プロジェクトを .dll としてコンパイルする必要があるか、参照を追加する必要がありますか? または、何らかの理由で、の可視性がMyServerManagerOPC internal-UA Web サイトにあるためです。

例外の前のデバッグ セッションは次のようになります。 ここに画像の説明を入力

MyServerManagerクラス (作業に対する唯一の重要な違いはカプセル化MyServerManagerである可能性があります):public

 public class MyServerManager : ServerManager
{

    private NodeManager _nodeManager;
    private ObjectModel _objectModel;

    /// <summary>
    /// Method is called (from SDK) when NodeManager starts up.
    /// </summary>
    /// <param name="rootNodeManager"></param>
    protected override void OnRootNodeManagerStarted(RootNodeManager rootNodeManager)
    {
        Console.WriteLine("Creating Node Manager.");

        _nodeManager = new NodeManager(this);
        _nodeManager.Startup();

        _objectModel = new ObjectModel(_nodeManager);
    }

    /// <summary>
    /// Creates an internal model of the given device and automatically creates nodes and callbacks
    /// </summary>
    /// <param name="device">AKOMI Device that will be shown on the Server</param>
    public void LinkObjectToModel(IDevice device)
    {
        if (_objectModel == null)
        {
            throw new NullReferenceException("hv: objectModel is not initilized, try starting the server first.");
        }

        Console.WriteLine("Register Device: " + device.GetType().Name);
        _objectModel.RegisterAkomiDevice(device, 0, 4);
    }

    /// <summary>
    /// Creates an internal model of the given entity and automatically creates nodes and callbacks
    /// </summary>
    public void LinkObjectToModel(object entity, string name, int curLvl, int maxLvl)
    {
        if (_objectModel == null)
        {
            throw new NullReferenceException("hv: objectModel is not initilized, try starting the server first.");
        }

        Console.WriteLine("Register Entity: " + name);
        _objectModel.RegisterEntity(entity, name, curLvl, maxLvl);
    }

}

ありがとう!

        Enabling this profile requires that you have a HTTPS certificate issued by a certificate authority
        in your root certificate store. You can create your own authority and add it to the root store or
        you can use authorities like VeriSign or Thawte.
