我需要在winform中实现识别功能，但是我根据wpf的demo进行配置，始终无法正确运行

每次运行到这里就报错

以下是我的测试代码

            engine = Engine.Create(MyScript.Certificate.MyCertificate.Bytes);

            string[] confDirs = new string[1];

            confDirs[0] = "conf";

            engine.Configuration.SetStringArray("configuration-manager.search-path", confDirs);

            var localFolder = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);

            var tempFolder = Path.Combine(localFolder, "MyScript", "tmp");

            engine.Configuration.SetString("content-package.temp-folder", tempFolder);

            engine.Configuration.SetString("text.configuration.name", "text");

            engine.Configuration.SetString("lang", "en_US");

            renderer = engine.CreateRenderer(150, 150, new RenderTargets());

            renderer.AddListener(new RendererListener());

            var toolController = engine.CreateToolController();

            toolController.SetToolForType(PointerType.PEN, PointerTool.PEN);

            // Create an editor

            var editor = engine.CreateEditor(renderer, toolController);

            editor.SetViewSize(615, 1412);

            editor.SetFontMetricsProvider(new FontMetricsProvider(150, 150, 1));

            // Create a new package

            string pk = MakeUntitledFilename();

            ContentPackage package;

            try

            {

                package = engine.CreatePackage(pk);

            }

            catch (Exception)

            {

                package = engine.OpenPackage(pk);

            }

            // Create a new part

            var part = package.CreatePart("Text");

            // Associate editor with the new part

            editor.Part = part;
